Description
The DM816x DaVinci video processors are a highly integrated, programmable platform that leverages TI's
DaVinci technology to meet the processing needs of the following applications: video encode, decode,
transcode, and transrate; video security; video conferencing; video infrastructure; media server; and digital
signage.
The device enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs)
to quickly bring to market devices featuring robust operating systems support, rich user interfaces, and
high processing performance through the maximum flexibility of a fully integrated mixed processor
solution. The device combines programmable video and audio processing with a highly integrated
peripheral set.
Key to the device are up to three high-definition video and imaging coprocessors (HDVICP2). Each
coprocessor can perform a single 1080p60 H.264 encode or decode or multiple lower resolution or frame
rate encodes and decodes. Multichannel HD-to-HD or HD-to-SD transcoding and multicoding are also
possible. With the ability to simultaneously process 1080p60 streams, the TMS320DM816x device is a
powerful solution for today's demanding HD video application requirements.
Programmability is provided by an ARM Cortex-A8 RISC CPU with NEON extension, TI C674x VLIW
floating-point DSP core, and high-definition video and imaging coprocessors. The ARM processor lets
developers keep control functions separate from audio and video algorithms programmed on the DSP and
coprocessors, thus reducing the complexity of the system software. The ARM Cortex-A8 32-bit RISC
processor with NEON floating-point extension includes: 32KB of instruction cache; 32KB of data cache;
256KB of L2 cache; 48KB of public ROM, and 64KB of RAM.
The rich peripheral set provides the ability to control external peripheral devices and communicate with
external processors. For details on each peripheral, see the related sections in this document and the
associated peripheral reference guides. The peripheral set includes: HD video processing subsystem
(HDVPSS), which provides output of simultaneous HD and SD analog video and dual HD video inputs; up
to two Gigabit Ethernet MACs (10 Mbps,100, Mbps, 1000 Mbps) with GMII and MDIO interface; two USB
ports with integrated 2.0 PHY; PCIe port x2 lanes GEN2 compliant interface, which allows the device to
act as a PCIe root complex or device endpoint; one 6-channel McASP audio serial port (with DIT mode);
two dual-channel McASP audio serial ports (with DIT mode); one McBSP multichannel buffered serial port;
three UARTs with IrDA and CIR support; SPI serial interface; SD and SDIO serial interface; two I2C
master and slave interfaces; up to 64 GPIO pins; seven 32-bit timers; system watchdog timer; dual DDR2
and DDR3 SDRAM interface; flexible 8-bit and 16-bit asynchronous memory interface; and up to two
SATA interfaces for external storage on two disk drives or more with the use of a port multiplier.
The device also includes an SGX530 3D graphics engine (available only on the TMS320DM8168 device)
to enable sophisticated GUIs and compelling user interfaces and interactions. Additionally, the device has
a complete set of development tools for both the ARM and DSP, including C compilers, a DSP assembly
optimizer to simplify programming and scheduling, and a Microsoft® Windows® debugger interface for
visibility into source code execution.
The C674x DSP core is the high-performance floating-point DSP generation in the TMS320C6000™ DSP
platform. The C674x floating-point DSP processor uses 32KB of L1 program memory and 32KB of L1 data
memory. Up to 32KB of L1P can be configured as program cache. The remaining is noncacheable nowait-state program memory. Up to 32KB of L1D can be configured as data cache. The remaining is
noncacheable no-wait-state data memory. The DSP has 256KB of L2 RAM, which can be defined as
SRAM, L2 cache, or a combination of both. All C674x L3 and off-chip memory accesses are routed
through a system MMU.

The device package has been specially engineered with Via Channel technology. This technology allows
use of 0.8-mm pitch PCB feature sizes in this 0.65-mm pitch package, and substantially reduces PCB
costs. Via Channel technology also allows PCB routing in only two signal layers due to the increased layer
efficiency of the Via Channel BGA technology.

C674x DSP CPU Description
The C674x central processing unit (CPU) consists of eight functional units, two register files, and two data
paths as shown in Figure 3-3. The two general-purpose register files (A and B) each contain 32 32-bit
registers for a total of 64 registers. The general-purpose registers can be used for data or can be data
address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in
register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 MSBs in the
next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one
instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units
perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from
memory to the register file and store results from the register file into memory.
The C674x CPU combines the performance of the C64x+ core with the floating-point capabilities of the
C67x+ core.
Each C674x .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x
32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add and
subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16
multiplies with add and subtract capabilities (including a complex multiply). There is also support for Galois
field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems
require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs and
produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding
capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The
32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms on
a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add and subtract operations on
a pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data
performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C674x core enhances the .S unit in several ways. On the previous cores, dual 16-bit MIN2 and MAX2
comparisons were only available on the .L units. On the C674x core they are also available on the .S unit
which increases the performance of algorithms that do searching and sorting. Finally, to increase data
packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit and
16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations.
Pack instructions return parallel results to output precision including saturation support.
Other new features include:
• SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size
associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.
• Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C674x
compiler can restrict the code to use certain registers in the register file. This compression is
performed by the code generation tools.
• Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.
• Exceptions Handling - Intended to aid the programmer in isolating bugs. The C674x CPU is able to
detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and
from system events (such as a watchdog time expiration).
• Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a
basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with
read, write, and execute permissions.

System Memory Management Unit (System MMU)
All C674x DSP accesses through the MDMA port are directed through the system memory management
unit (System MMU) module where they are remapped to physical system addresses. This protects the
ARM Cortex-A8 memory regions from accidental corruption by C674x code and allows for direct allocation
of buffers in user space without the need for translation between ARM and DSP applications.
In addition, accesses by the EDMA TC0 may optionally be routed through the System MMU. This allows
EDMA Channel 0 to be used by the DSP to perform transfers using only the known virtual addresses of
the associated buffers. The MMU_CFG register in the Control Module is used to enable and disable use of
the DSP EDMA MMU by the EDMA TC.
For details on the System MMU features and registers, see the System MMU chapter of the
TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (literature number
SPRUGX8).

3.6
Inter-Processor Communication
This device is a multi-core device that requires software to efficiently manage and communicate between
the cores. The following are the main features that need to be implemented by such software:
1. Device management of the slave processors from the host processor.
2. Inter-processor communication between the cores for transfer and exchange of information between
them.
On this device, the host processor is usually the ARM Cortex-A8. This processor is responsible for
bootloading the slave processors (C674x). Bootloading includes power management of the slaves
(powerup and powerdown and other power management), reset control (reset and release of the slave
processor) and setting the entry point of the slave executable into the appropriate register. This device has
a power-on reset (POR) and warm reset. For the POR reset, the ARM Cortex-A8 is taken out of reset and
it boots from its boot ROM. Once booted, the ARM Cortex-A8 bootloads the C674x processor.
For implementing efficient inter-processor communication between the multiple cores on the device, the
following hardware features are provided:
• Mailbox interrupts
• Hardware spinlocks
Mailboxes provide a mechanism for one processor to write a value to a register and send an interrupt to
another processor. Spinlocks facilitate access to shared resources in the system.
3.6.1
Mailbox Module
The device Mailbox module facilitates communication between the ARM Cortex-A8, C674x DSP, and the
Media Controller. It consists of twelve mailboxes, each supporting communication between two of the
above processors. The sender sends information to the receiver by writing a message to the mailbox
registers. Interrupt signaling is used to notify the receiver that a message has been queued or to notify the
sender about an overflow situation.
The Mailbox module supports the following features (see Figure 3-4):
• 12 mailboxes

through power-control signals. It integrates enhanced features to allow the device to adapt energy
consumption dynamically, according to changing application and performance requirements. The
innovative hardware architecture allows a substantial reduction in leakage current.
The PRCM module is composed of two main entities:
• Power reset manager (PRM): Handles the power, reset, wake-up management, and system clock
source control (oscillator)
• Clock manager (CM): Handles the clock generation, distribution, and management.
Table 3-7 lists the physical addresses of the PRM and CM modules. Table 3-8 through Table 3-25 provide
register mapping summaries of the PRM and CM registers.
For more details on the PRCM, see Section 8 of this data sheet, Power, Reset, Clocking and Interrupts,
and the PRCM chapter of the TMS320DM816x DaVinci Digital Media Processors Technical Reference
Manual (literature number SPRUGX8).

SGX530 (DM8168 only)
The SGX530 is a vector and 3D graphics accelerator for vector and 3-dimensional (3D) graphics
applications. The SGX530 graphics accelerator efficiently processes a number of various multimedia data
types concurrently:
• Pixel data
• Vertex data
• Video data.
This is achieved using a multi-threaded architecture using two levels of scheduling and data partitioning
enabling zero overhead task switching.
The SGX530 has the following major features:
• Vector graphics and 3D graphics.
• Tile-based architecture.
• Universal Scalable Shader Engine (USSE) - multi-threaded engine incorporating pixel and vertex
shader functionality. USSE™
• Advanced shader feature set - in excess of Microsoft VS3.0, PS3.0, and OpenGL 2.0.
• Industry standard API support - OpenGL ES 1.1 and 2.0, OpenVG v1.1.
• Fine-grained task switching, load balancing, and power management.
• Advanced geometry direct memory access (DMA) driven operation for minimum CPU interaction.
• Programmable high-quality image anti-aliasing.
• PowerVR® SGX core MMU for address translation from the core virtual address to the external
physical address (up to 4GB address range).
• Fully-virtualized memory addressing for OS operation in a unified memory architecture.
• Advanced and standard 2D operations [for example, vector graphics, block level transfers (BLTs),
raster operations (ROPs)].

SPRS614F – MARCH 2011 – REVISED MARCH 2015
Memory Map Summary
The device has multiple on-chip memories associated with its processors and various subsystems. To
help simplify software development a unified memory map is used where possible to maintain a consistent
view of device resources across all bus masters.
The device system memory mapping is broken into four 1-GB quadrants for target address spaces
allocation. The four quadrants are labeled Q0, Q1, Q2 and Q3 for a total of 4-GB 32-bit address space.
(HDVPSS includes a thirty-third address bit for an additional 4GB of address range; this is for virtual
addressing and not physical memory addressing.) Inside each quadrant, system targets are mapped on 4MB boundary (except EDMA targets which are decreased to 1-MB regions).
3.9.1
L3 Memory Map
The L3 high-performance interconnect is based on a Network-on-Chip (NoC) interconnect infrastructure.
The NoC uses an internal packet-based protocol for forward (read command, write command with data
payload) and backward (read response with data payload, write response) transactions. All exposed
interfaces of this NoC interconnect, both for targets and initiators, comply with the OCPIP2.2 reference
standard.
Table 3-26 shows the general device level-3 (L3) memory map. The table represents the physical
addresses used by the L3 infrastructure. Some processors within the device (such as Cortex™-A8 ARM,
C674x DSP) may re-map these targets to different virtual addresses through an internal or external MMU.
Processors without MMUs and other bus masters use these physical addresses to access L3 regions.
Note that not all masters have access to all L3 regions, but only those with defined connectivity, as shown
in Table 7-1. For a list of the specific peripherals attached to each of the Level-4 (L4) peripheral ports see
Section 7.2. The L3 interconnect returns an address-hole error if any initiator attempts to access a target
to which it has no connection.

(1) The first section of GPMC memory (0x0 - 0x00FF_FFFF) is reserved for BOOTROM. Accessible memory starts at location
0x0100_0000.
(2) For more information about McASP registers accessed through the DAT port, see Table 9-78.
(3) These accesses occur through the DDR DMM Tiler Ports. The DMM will split address ranges internally to address DDR EMIF and DDR
DMM control registers.
(4) DDR EMIF0 and DDR EMIF1 addresses may be contiguous or bank interleaved depending on configuration of the DDR DMM; for more
details, see the DDR DMM documentation.

TILER Extended Addressing Map
The Tiling and Isometric Lightweight Engines for Rotation (TILER) ports are mainly used for optimized 2-D
block accesses. The TILER also supports rotation of the image buffer at 0º, 90º, 180º, and 270º, with
vertical and horizontal mirroring.
The TILER includes an additional 4-GB addressing range to access the frame buffer in these rotated and
mirrored views. This range requires a thirty-third bit of address and is only accessible to peripherals that
require access to the multiple views. On the device, this is limited to the HD Video Processing Subsystem
(HDVPSS). (Other peripherals, based on ConnID, may access any one single view through the 512-MB
TILER window region located in the base 4-GB range.)
The HDVPSS may use the virtual address space of 4GB (0x1:0000:0000 – 0x1:FFFF:FFFF) since various
VPDMA clients of the HDVPSS may need to simultaneously access multiple 2-D images with different
orientations of the image buffers.
The top 4-GB address space is divided into eight sections of 512MB each. These eight sections
correspond to the eight different orientations as shown in Table 3-29.

Cortex™-A8 Memory Map
The Cortex™-A8 includes an memory management unit (MMU) to translate virtual addresses to physical
addresses which are then decoded within the Host ARM Subsystem. The subsystem includes its own
ROM and RAM, as well as configuration registers for its interrupt controller. These addresses are hardcoded within the subsystem. In addition, the upper 2GB of address space is routed to a special port
(Master 0) intended for low-latency access to DDR memory. All other physical addresses are routed to the
L3 port (Master 1) where they are decoded by the device infrastructure. The Cortex™-A8 memory map is
shown in Table 3-30.

C674x Memory Map
Because the C674x DSP has specific hardwired address decoding built in, the C674x memory map is
slightly different than that of the Cortex™-A8. The C674x has a separate CFG bus which is used to
access L4 peripherals and its UMAP1 bus has a direct connection into HDVICP2 SL2 (HDVICP2-0 and
HDVICP2-1 only) memories. All C674x MDMA port accesses are routed through the System MMU for
address translation.

Terminal Functions
The terminal functions tables identify the external signal names, the associated pin (ball) numbers along
with the mechanical package designator, the pin type, whether the pin has any internal pullup or pulldown
resistors, and a functional pin description. Bolded pin names denote the muxed pin function being
described in each table. For more detailed information on device configurations, peripheral selection,
multiplexed pin, and shared pin see Section 6, Device Configurations.

I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground, A = Analog signal.
PULL: A / B, where:
A is the state of the internal pull resistor during POR reset
B is the state of the internal pull resistor after POR and Warm reset are de-asserted and during Warm reset
IPD = Internal Pulldown Enabled, IPU = Internal Pullup Enabled, DIS = Internal Pull Disabled
DRIVE: A / B, where;
A is the driving state of the pin during POR reset
B is the driving state of the pin after POR and Warm reset are de-asserted and during Warm reset
H = Driving High, L = Driving Low, Z = 3-State
For more detailed information on pullup and pulldown resistors and situations where external pullup and pulldown resistors are required,
see Section 6.3.1, Pullup and Pulldown Resistors.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values are with respect to VSS.
For supply voltage pins, DVDD_DDRx:
• 1.5 V is used for DDR3 SDRAM.
• 1.8 V is used for DDR2 SDRAM.
A heat dissipation solution is required for proper device operation. Thermal performance of the overall system must be carefully
considered to ensure conformance with the recommended operating conditions. Heat generated by this device must be removed with
the help of heat sinks, heat spreaders, or airflow. SmartReflex can significantly lower the power consumption of this device and its use is

This device supports, and requires the use of, SmartReflex technology with Adaptive Voltage Scaling based on die temperature and
performance. The SmartReflex codes output from the device correspond to up to 32 linear voltage steps within the specified voltage
range (32 steps is the recommended software upper limit and is not constrained by the silicon design), with the option to use fewer
steps if desired, with a minimum of eight steps. TI requires that users design a supply that can handle multiple voltage steps within this
range with ± 5% tolerances. Not incorporating a flexible supply may limit the system's ability to use the power saving capabilities of the
SmartReflex technology. TI recommends using a fault-tolerant power supply design to protect against over-current conditions. For more
details about adaptive voltage scaling for this device, see the AVS FAQ. For AVS disable data to aid in design of robust power supplies
that may withstand momentary AVS control failure, see the device Power Estimation Spreadsheet (literature number SPRABK3).
The initial CVDD voltage at power on must be 1.00V nominal (for CYGA2 and CYG4 devices) or 1.05V nominal (for CYG and CYG2
devices) and it must transition to the AVS target value adjusted by a AVS driver. This is required to maintain full power functionality and
reliability targets specified by TI.
SRnom refers to the unique SmartReflex core supply voltage set from the factory for each individual device.
Upper range limit of 1.10 nominal value allowed.
For supply voltage pins, DVDD_DDRx:
• 1.5 V is used for DDR3 SDRAM.
• 1.8 V is used for DDR2 SDRAM.
Oscillator ground (DEVOSC_VSS) must be kept separate from other grounds and connected directly to the crystal load capacitor
ground.
DDR_VREF is expected to equal 0.5DVDD_DDRx of the transmitting device and to track variations in the DVDD_DDRx.

6 Device Configurations
6.1
Control Module
The device control module includes status and control logic not addressed within the peripherals or the
remainder of the device infrastructure. This module is the primary point of control for the following areas of
the device:
• Functional IO multiplexing
• Device status
• Static device configuration
• Open-core protocol (OCP) interface for standard and customer programmable e-Fuse bit shift
registers.
The control module primarily implements a bank of registers accessible (read and write) by the software
along with some read-only registers carrying status information. Most register bits are exported as control
signals for other logic blocks on the device. Certain control module registers have default values based
upon the device type as decoded from e-Fuse.
The read and write registers can be divided into the following classes:
• Static device configuration registers
• Status and configuration registers
• Boot registers
Table 6-1 shows the general register groupings and Table 6-2 through Table 6-4 provide register
summaries for each group.

Revision Identification
The silicon revision can be read in the DEVREV bit field value of the device identification (DEVICE_ID)
register (located at 0x4814 0600). The DEVREV field of the DEVICE_ID register changes between silicon
revisions. Table 6-5 lists the contents of the device revision (DEVREV) field value for each revision of the
device.

Debugging Considerations
Pullup and Pulldown Resistors
Proper board design should ensure that input pins to the device always be at a valid logic level and not
floating. This may be achieved via pullup and pulldown resistors. The device features internal pullup (IPU)
and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for
external pullup or pulldown resistors.
An external pullup or pulldown resistor needs to be used in the following situations:
• Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external pullup
or pulldown resistor is strongly recommended, even if the IPU or IPD matches the desired value or
state.
• Other Input Pins: If the IPU or IPD does not match the desired value or state, use an external pullup or
pulldown resistor to pull the signal to the opposite rail.
For the boot and configuration pins (listed in Table 4-1, Boot Terminal Functions), if they are both routed
out and 3-stated (not driven), it is strongly recommended that an external pullup or pulldown resistor be
implemented. Although, internal pullup and pulldown resistors exist on these pins and they may match the
desired configuration value, providing external connectivity can help ensure that valid logic levels are
latched on these device boot and configuration pins. In addition, applying external pullup or pulldown
resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in
switching operating modes.
Tips for choosing an external pullup or pulldown resistor:
• Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure
to include the leakage currents of all the devices connected to the net, as well as any internal pullup or
pulldown resistors.
• Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of
all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all
inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of
the limiting device; which, by definition, have margin to the VIL and VIH levels.
• Select a pullup or pulldown resistor with the largest possible value; but, which can still ensure that the
net will reach the target pulled value when maximum current from all devices on the net is flowing
through the resistor. The current to be considered includes leakage current plus, any other internal and
external pullup and pulldown resistors on the net.

SPRS614F – MARCH 2011 – REVISED MARCH 2015
For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance
value of the external resistor. Verify that the resistance is small enough that the weakest output buffer
can drive the net to the opposite logic level (including margin).
Remember to include tolerances when selecting the resistor value.
For pullup resistors, also remember to include tolerances on the DVDD rail.
For most systems, a 1-kΩ resistor can be used to oppose the IPU or IPD while meeting the above criteria.
Users should confirm this resistor value is correct for their specific application.
For most systems, a 20-kΩ resistor can be used to compliment the IPU or IPD on the boot and
configuration pins while meeting the above criteria. Users should confirm this resistor value is correct for
their specific application.
For most systems, a 20-kΩ resistor can also be used as an external pullup or pulldown on the pins that
have IPUs or IPDs disabled and require an external pullup or pulldown resistor while still meeting the
above criteria. Users should confirm this resistor value is correct for their specific application.
For more detailed information on input current (II), and the low-level or high-level input voltages (VIL and
VIH), see , Electrical Characteristics Over Recommended Ranges of Supply Voltage and Operating
Temperature.
For the internal pullup and pulldown resistors for all device pins, see the peripheral-specific or systemspecific terminal functions tables in Section 4.2.
6.4
Boot Sequence
The boot sequence is a process by which the device's memory is loaded with program and data sections,
and by which some of the device's internal registers are programmed with predetermined values. The boot
sequence is started automatically after each device-level global reset. For more details on device-level
global resets, see Section 8.2. There are several methods by which the memory and register initialization
can take place. Each of these methods is referred to as a boot mode. The boot mode to be used is
selected at reset. The device is booted through multiple means—primary bootloaders within internal ROM
or EMIF4, and secondary user bootloaders from peripherals or external memories. The maximum size of
the boot image is 255KB (ROM uses 1KB internally). Boot modes, pin configurations, and register
configurations required for booting the device, are described in the following subsections.
The following boot modes are supported:
• NOR Flash boot (muxed and non-muxed, 8-bit or 16-bit)
• NAND Flash boot (SLC and MLC with BCH ECC, 8-bit or 16-bit)
• SPI boot (EEPROM or Flash, SPI mode 3, 24-bit)
• SD boot (SD cards)
• EMAC boot (TFTP client)
• UART boot (X-modem client)
• PCIe boot (client mode, PCIe 32 and PCIe 64).
The state of the device after boot is determined by sampling the input states of the BTMODE[4:0] pins
when device reset (POR or RESET) is deasserted. The sampled values are latched into the
CONTROL_STATUS register, which is part of the system configuration (SYSCFG) module.
The BTMODE [4:0] values determine the boot mode order according to Table 6-6. The first boot mode
listed for each BTMODE[4:0] configuration is executed as the primary boot mode. If the primary boot
mode fails, the second, third, and fourth boot modes are executed, in that order, until a successful boot is
completed.
Additional boot configuration pins determine the following system boot settings as shown in Table 4-1:
• GPMC CS0 Default Bus Width
• GPMC Wait Enable

Pin Multiplexing Control
Device-level pin multiplexing is controlled on a pin-by-pin basis by the MUXMODE bits of the PINCTRL1 PINCTRL321 registers in the SYSCFG module. The default state for each multiplexed pin is MUXMODE =
0x000.
Pin multiplexing selects which of several peripheral pin functions control the pin's IO buffer output data
values.
The input from each pin is routed to all of the peripherals that share the pin, regardless of the MUXMODE
setting. For details, see the table below and the MUXED column in the each of the Terminal Functions
tables in Section 4.2.

How to Handle Unused Pins
When device signal pins are unused in the system, they can be left unconnected unless otherwise
instructed in the Terminal Functions tables. For unused input pins, the internal pull resistor should be
enabled, or an external pull resistor should be used, to prevent floating inputs. All supply pins must always
be connected to the correct voltage, even when their associated signal pins are unused, as instructed in
the Terminal Functions tables in Section 4.2.

7 System Interconnect
The L3 interconnect allows the sharing of resources, such as peripherals and external or on-chip
memories, between all the initiators of the platform. The L4 interconnects control access to the
peripherals.
Transfers between initiators and targets across the platform are physically conditioned by the chip
interconnect.
7.1
L3 Interconnect
The L3 topology is driven by performance requirements, bus types, and clocking structure. Figure 7-1
shows the interconnect of the device and the main modules and subsystems in the platform. Arrows
indicate the master-and-slave relationship, not data flow. Master-and-slave connectivity is shown in
Table 7-1.

L4 Interconnect
The L4 interconnect is a non-blocking peripheral interconnect that provides low-latency access to a large
number of low-bandwidth, physically-dispersed target cores. The L4 can handle incoming traffic from up to
four initiators and can distribute those communication requests to and collect related responses from up to
63 targets.
The device provides three interfaces with L3 interconnect for high-speed peripheral and standard
peripheral. Figure 7-2 and Table 7-2 show the L4 bus architecture and memory-mapped peripherals.

Power Supplies
8.1.1
Voltage and Power Domains
The device has the following voltage domains:
• 1-V adaptive voltage scaling (AVS) domain - Main voltage domain for all modules
• 1-V constant domain - Memories, PLLs, DACs, DDR IOs, HDMI, and USB PHYs
• 1.8-V constant domain - PLLs, DACs, HDMI, and USB PHYs
• 3.3-V constant domain - IOs and USB PHY
• 1.5-V constant domain - DDR IOs, PCIe, and SATA SERDES
• 0.9-V constant domain - USB PHY
These domains define groups of modules that share the same supply voltage for their core logic. Each
voltage domain is powered by dedicated supply voltage rails. For the mapping between voltage domains
and the supply pins associated with each, see Table 4-33.
Note: A regulated supply voltage must be supplied to each voltage domain at all times, regardless of the
power domain states.
8.1.2
Power Domains
The device's 1-V AVS and 1-V constant voltage domains have seven power domains that supply power to
both the core logic and SRAM within their associated modules. All other voltage domains have only
always-on power domain.
Within the 1-V AVS and 1-V constant voltage domains, each power domain, except for the always-on
domain, has an internal power switch that can completely remove power from that domain. At power-up,
all domains, except always-on, come-up as power gated. Since there is an always-on domain in each
voltage domain, all power supplies are expected to be ON all the time (as long as the device is in use).
For details on powering up or powering down the device power domains, see the TMS320DM816x
DaVinci Digital Media Processors Technical Reference Manual (SPRUGX8).
Note: All modules within a power domain are unavailable when the domain is powered OFF. For
instructions on powering ON or powering OFF the domains, see the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (SPRUGX8).

This power domain contains HDVICP2-1. If HDVICP2-1 is not used, it can be power gated.
HDVICP2-2 Domain
This power domain contains HDVICP2-2. If HDVICP2-2 is not used, it can be power gated.
Note: Three HDVICP2 modules are available on the DM8168 and DM8167 devices and two HDVICP2
modules (HDVICP2-0 and HDVICP2-1) are available on the DM8165 devices.
Graphics Domain
This domain contains the SGX530 (available only on the DM8168 device).
Active Domain
The active domain has all modules that are only needed when the system is in "active" state. In any of
the standby states, these modules are not needed. This domain contains the C674x DSP and
HDVPSS peripheral.

8.1.4
SPRS614F – MARCH 2011 – REVISED MARCH 2015
The default domain contains modules that might be required even in standby mode. Having them in a
separate power domain allows customers to power gate these modules when in standby mode. This
domain has the DDR, SATA, PCIe, Media Controller and USB peripherals.
Always-On Domain
The always-on domain contains all modules that are required even when the system goes to standby
mode. This includes the host ARM and modules that generate wake-up interrupts (for example, UART,
RTC, GPIO, EMAC) as well as other low-power IOs.
SmartReflex™
The device contains SmartReflex modules that are required to minimize power consumption on the
voltage domains using external variable-voltage power supplies. Based on the device process,
temperature, and desired performance, the SmartReflex modules advise the host processor to raise or
lower the supply voltage to each domain for minimal power consumption. The communication link between
the host processor and the external regulators is a system-level decision and can be accomplished using
GPIOs or I2C.
The major technique employed by SmartReflex in the device is adaptive voltage scaling (AVS). Based on
the silicon process and temperature, the SmartReflex modules guide software in adjusting the core 1-V
supply voltage within the desired range. This technique is called adaptive voltage scaling (AVS). AVS
occurs continuously and in real time, helping to minimize power consumption in response to changing
operating conditions.
NOTE
Implementation of SmartReflex AVS is required for proper device operation.
8.1.5
Memory Power Management
The device memories offer three different modes to save power when memories are not being used;
Table 8-1 provides the details.

The device provides a feature that allows the software to put the chip-level memories (C674x L2, OCMC
RAMs) in any of the three (LS, DS, and SD) modes. There are control registers in the control module to
control the power-down state of C674x L2, OCMC RAM0, and OCMC RAM1. There are also status
registers that can be used during power-up to check if memories are powered-up. For detailed instructions
on entering and exiting from light sleep and deep sleep modes, see the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (SPRUGX8).
Memories inside switchable domains go to the shut down (SD) state whenever the power domain goes to
the OFF state. Memories come back to functional state along with the domain power-up.
In order to reduce SRAM leakage, many SRAM blocks can be switched from active mode to shut-down
mode. When SRAM is put in shut-down mode, the voltage supplied to it is automatically removed and all
data in that SRAM is lost.
All SRAM located in a switchable power domain (all domains except always-on) automatically enters shutdown mode whenever its assigned associated power domain goes to the OFF state. The SRAM returns to
the active state when the corresponding power domain returns to the ON state.

IO Power-Down Modes
The DDR3 IOs are put into power-down mode automatically when the default power domain is turned
OFF.
The HDMI PHY controller is in the always-on power domain, so software must configure the PHY into
power-down mode.
There is no power-down mode for the other 3.3-V IOs.
8.1.7
Supply Sequencing
The device power supplies must be sequenced in the following order:
1. 3.3 V
2. 1-V AVS
3. 1-V Constant
4. 1.8 V
5. 1.5 V
6. 0.9 V
Each supply (represented by VDDB in Figure 8-1) must begin actively ramping between 0 ms and 50 ms
after the previous supply (represented by VDDA in Figure 8-1) in the sequence has reached 80% of its
nominal value, as shown in Figure 8-1.

can be found in Section 4.2, Terminal Functions.
8.1.8
Power-Supply Decoupling
Recommended capacitors for power supply decoupling are all 0.1 µF in the smallest body size that can be
used. Capacitors are more effective in the smallest physical size to limit lead inductance. For example,
0402 sized capacitors are better than 0603 sized capacitors, and so on.

PLL supplies benefit from filters or ferrite beads to keep the noise
from causing clock jitter. The minimum recommendation is a ferrite
bead with a resonance at 100 MHz along with at least one capacitor
on the device side of the bead. Additional recommendation is to add
one capacitor just before the bead to form a Pi filter. The filter needs
to be as close as possible to the device pin, with the device-side
capacitor being the most important component to be close to the
device pin. PLL pins close together can be combined on the same
supply. PLL pins spaced farther away from one another may need
individual filtered supplies.
It is recommended to have one bulk (15 µF or larger) capacitor for
every 10 smaller capacitors placed as closely as possible to the
device.
DDR-related supply capacitor numbers are provided in Section 9.3.

Power-On Reset (POR pin)
Power-on reset (POR) is initiated by the POR pin and is used to reset the entire chip, including the test
and emulation logic. POR is also referred to as a cold reset since it is required to be asserted when the
devices goes through a power-up cycle. However, a device power-up cycle is not required to initiate a
power-on reset.
The following sequence must be followed during a power-on reset:
1. Wait for the power supplies to reach normal operating conditions while keeping the POR pin asserted.
2. Wait for the input clock sources SERDES_CLKN and SERDES_CLKNP to be stable (if used by the

system) while keeping the POR pin asserted (low).
3. Once the power supplies and the input clock source are stable, the POR pin must remain asserted
(low) for a minimum of 32 DEV_MXI cycles. Within the low period of the POR pin, the following
happens:
(a) All pins enter a Hi-Z mode.
(b) The PRCM asserts reset to all modules within the device.
(c) The PRCM begins propagating these clocks to the chip with the PLLs in bypass mode.
4. The POR pin may now be deasserted (driven high). When the POR pin is deasserted (high):
(a) The BOOT pins are latched.
(b) Reset to the ARM Cortex-A8 is de-asserted, provided the processor clock is running.
(c) All other domain resets are released, provided the domain clocks are running.
(d) The clock, reset, and power-down state of each peripheral is determined by the default settings of
the PRCM.
(e) The ARM Cortex-A8 begins executing from the default address (Boot ROM).
8.2.3
External Warm Reset (RESET pin)
An external warm reset is activated by driving the RESET pin active-low. This resets everything in the
device, except the ARM Cortex-A8 interrupt controller, test, and emulation. An emulator session stays
alive during warm reset.
The following sequence must be followed during a warm reset:
1. Power supplies and input clock sources should already be stable.
2. The RESET pin must be asserted (low) for a minimum of 32 DEV_MXI cycles. Within the low period of
the RESET pin, the following happens:
(a) All pins, except test and emulation pins, enter a Hi-Z mode.
(b) The PRCM asserts reset to all modules within the device, except for the ARM Cortex-A8 interrupt
controller, test, and emulation.
(c) RSTOUT is asserted.
3. The RESET pin may now be de-asserted (driven high). When the RESET pin is de-asserted (high):
(a) The BOOT pins are latched.
(b) Reset to the ARM Cortex-A8 and modules without a local processor is de-asserted, with the
exception of the ARM Cortex-A8 interrupt controller, test, and emulation.
(c) RSTOUT is de-asserted.
(d) The clock, reset, and power-down state of each peripheral is determined by the default settings of
the PRCM.
(e) The ARM Cortex-A8 begins executing from the default address (Boot ROM).
(f) Since the ARM Cortex-A8 interrupt controller is not impacted by warm reset, application software
needs to explicitly clear all pending interrupts in the ARM Cortex-A8 interrupt controller.
8.2.4
Emulation Warm Reset
An emulation warm reset is activated by the on-chip emulation module. It has the same effect and
requirements as an external warm reset (RESET), with the exception that it does not re-latch the BOOT
pins.
The emulator initiates an emulation warm reset via the ICEPick module. To invoke the emulation warm
reset via the ICEPick module, the user can perform the following from the Code Composer Studio™ IDE
menu:
Debug → Advanced Resets → System Reset.

Watchdog Reset
A watchdog reset is initiated when the watchdog timer counter reaches zero. It has the same effect and
requirements as an external warm reset (RESET), with the exception that it does not re-latch the BOOT
pins. In addition, a watchdog reset always results in RSTOUT being asserted.
8.2.6
Software Global Cold Reset
A software global cold reset is initiated under software control. It has the same effect and requirements as
a power-on reset (POR), with the exception that it does not re-latch the BOOT pins.
Software initiates a software global cold reset by writing to RST_GLOBAL_COLD_SW in the
PRM_RST_CTRL register.

PRM_RST_CTRL register.
8.2.8
Test Reset (TRST pin)
A test reset is activated by the emulator asserting the TRST pin. The only effect of a test reset is to reset
the emulation logic.
8.2.9
Local Reset
The local reset for various modules within the device is controlled by programming the PRCM and the
module's internal registers. Only the associated module is reset when a local reset is asserted, leaving the
rest of the device unaffected.
For details on local reset, see the PRCM chapter of the TMS320DM816x DaVinci Digital Media
Processors Technical Reference Manual (SPRUGX8) and individual subsystem and peripheral user's
guides.
8.2.10 Reset Priority
If any of the above reset sources occur simultaneously, the device only processes the highest-priority
reset request. The reset request priorities, from high to low, are as follows:
1. Power-on reset (POR)
2. Test reset (TRST)
3. External warm reset (RESET)
4. Emulation warm resets
5. Watchdog reset
6. Software global cold and warm resets.
8.2.11 Reset Status Register
The Reset Status Register (PRM_RSTST) contains information about the last reset that occurred in the
system. For more information on this register, see the PRCM chapter of the TMS320DM816x DaVinci
Digital Media Processors Technical Reference Manual (SPRUGX8).
8.2.12 PCIe Reset Isolation
The device supports reset isolation for the PCI Express (PCIe) module. This means that the PCI Express
subsystem can be reset without resetting the rest of the device.

When the device is a PCI Express Root Complex (RC), the PCIe subsystem can be reset by software
through the PRCM. Software should ensure that there are no ongoing PCIe transactions before asserting
this reset by first taking the PCIe subsystem into the IDLE state by programming the register
CM_DEFAULT_PCI_CLKCTRL inside the PRCM. After bringing the PCIe subsystem out of reset, bus
enumeration should be performed again and should treat all endpoints (EP) as if they had just been
connected.
When the device is a PCI Express Endpoint (EP), the PCIe subsystem generates an interrupt when an inband reset is received. Software should process this interrupt by putting the PCIe subsystem in the IDLE
state and then asserting the PCIe local reset through the PRCM.
All device-level resets mentioned in the previous sections, except Test Reset, also reset the PCIe
subsystem. Therefore, the device should issue a Hot Reset to all downstream devices and re-enumerate
the bus upon coming out of reset.
8.2.13 RSTOUT
The RSTOUT pin on the device reflects device reset status and is de-asserted (high) when the device is
out of reset. In addition, this output is always 3-stated and the internal pull resistor is disabled on this pin
while POR or RESET is asserted; therefore, an external pullup or pulldown can be used to set the state of
this pin (high or low) while POR or RESET is asserted. For more detailed information on external pullups
and pulldowns, see Section 6.3.1. This output is always asserted low when any of the following resets
occur:
• Power-on reset (POR)
• External warm reset
• Emulation warm reset (RESET)
• Software global cold or warm reset
• Watchdog timer reset.
The RSTOUT pin remains asserted until PRCM releases the host ARM Cortex-A8 processor for reset.
8.2.14 Effect of Reset on Emulation and Trace
The device emulation and trace is only reset by the following sources:
• Power-on reset (POR)
• Software global cold reset
• Test reset (TRST).
Other than these three, none of the other resets affect emulation and trace functionality.
8.2.15 Reset During Power Domain Switching
Each power domain has a dedicated warm reset and cold reset. Warm reset for a power domain is
asserted under either of the following two conditions:
1. A power-on reset, external warm reset, emulation warm reset, or software global cold or warm reset
occurs.
2. When that power domain switches from the ON state to the OFF state.
Cold reset for a power domain is asserted under either of the following two conditions:
1. A power-on reset or software global cold reset occurs.
2. When that power domain switches from the ON state to the OFF state.
8.2.16 Pin Behaviors at Reset
When any reset (other than test reset) described in Section 8.2.1 is asserted, all device pins are put into a
Hi-Z state except for:

Device Clock Inputs
The device has four on-chip PLLs and one reference clock which are generated by on-chip oscillators. In
addition to the 27-MHz reference clock, a 100-MHz differential clock input is required for SATA and PCIe.
A third clock input is an optional 32.768-kHz clock input (no on-chip oscillator) for the RTC.
The device clock input (DEV_MXI and DEV_CLKIN) is used to generate the majority of the internal
reference clocks. An external square-wave clock can be supplied to DEV_CLKIN instead of using a crystal
input. The device clock should be 27 MHz.
Section 8.3.1.1 provides details on using the on-chip oscillators with external crystals for the 27-MHz
system oscillator.
8.3.1.1
Using the Internal Oscillators
When the internal oscillators are used to generate the device clock, external crystals are required to be
connected across the MXI and MXO pins, along with two load capacitors, as shown in Figure 8-5. The
external crystal load capacitors should also be connected to the associated oscillator ground pin
(DEVOSC_VSS). The capacitors should not be connected to board ground (VSS).

SERDES_CLKN and SERDES_CLKP Input Clock
A high-quality, low-jitter differential clock source is required for the PCIe and SATA PHYs. The clock is
required to be AC coupled to the device's SERDES_CLKP and SERDES_CLKN pins according to the
specifications in Table 8-11. Both the clock source and the coupling capacitors should be placed
physically as close as possible to the processor.
When the PCIe interface is used, the SERDES_CLKN or SERDES_CLKP clock is required to meet the
REFCLK AC specifications outlined in the PCI Express Card Electromechanical Specification (Gen.1 and
Gen.2). When the SATA interface is used, the SERDES_CLKN or SERDES_CLKP clock is required to
meet the specifications in Table 8-8. When both the PCIe and SATA interfaces are used, both sets of
specifications must be met simultaneously.

The value of this capacitor depends on several factors including differential input clock swing. For a 100-MHz differential clock with an
approximate 1-V voltage swing, the recommended typical value for the SERDES clock AC coupling capacitors is 270 pF. Deviating from
this recommendation can result in the reduction of clock signal amplitude or lowering the noise rejection characteristics.

PLLs
The device contains four embedded PLLs (Main, Audio, Video and DDR) that provide clocks to different
parts of the system. For a high-level view of the device clock architecture, including the PLL reference
clock sources and connections, see Figure 8-4.
The reference clock for most of the PLLs comes from the DEV_CLKIN input clock. Also, each PLL
supports a bypass mode in which the reference clock can be directly passed to the PLL CLKOUT. All
device PLLs (except the DDR PLL) come-up in bypass mode after reset.
Flying-adder PLLs are used for all the on-chip PLLs. Figure 8-8 shows the basic structure of the flyingadder PLL.

Figure 8-8. Flying-Adder PLL
The flying-adder PLL has two main components: a multi-phase PLL and the flying-adder synthesizer. The
multi-phase PLL takes an input reference clock (fr), multiplies it with factor, N, and provides a K-phase
output to the flying-adder synthesizer. The flying-adder synthesizer takes this multi-phase clock input and
produces a variable frequency clock (fs). There can be a post divider on this clock which takes in clock fs
and drives out clock fo. The frequency of the clock driven out is given by:
é
(Ν * Κ ) ù * fr
fo = ê
(
FREQ
* P * M )úû
ë
There can be multiple flying-adder synthesizers attached to one multi-phase PLL to generate different
frequencies. In this case, FREQ (4 bits of integer and 24 bits of fractional value) and M (1 to 255) values
can be adjusted for each clock separately, based on the frequency needed. The multi-phase PLL used in
this device has a value of K = 8.
For details on programming the device PLLs, see the PLL chapter of the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (SPRUGX8).

PLL Programming Limits
The PLL and Flying Adder Synthesizers support generation of a wide range of clocks that are all
generated from the same input clock source. Therefore, these clocks are all synchronous. The flyingadder synthesizers take the multi-phase clock from the PLL and produce variable frequency clocks (fs) as
stated in the previous section. Each variable frequency clock is then divided by a post divider before use.
The clock outputs from the PLL, Synthesizer and Post Divider contain period variations that must be
considered. The minimum period of the generated clock is effectively the maximum clock rate. Different
configurations of the PLL dividers, Synthesizer and output dividers will have larger or smaller amounts of
phase variation. The equation below will calculate the minimum cycle period for a given set of settings.
The result of the following minimum cycle equation must be greater than the value shown in Table 8-13.
The first term of the below equation is a characteristic of the Flying Adder PLL. The selection of M*FREQ
is important. Choosing a non-integer value of M*FREQ will cause larger period variation and a higher peak
instantaneous frequency. Use of non-integer M*FREQ can be done to create specific average frequencies
at the cost of higher phase variation. Using integer values of M*FREQ result in minimum phase variation.
The second and third terms are PLL phase jitter terms associated with the frequency synthesis. The
second term is about 20ps and the third is normally 10ps.
Please refer to the Technical Reference Manual (SPRUGX8) for examples using this equation. The TRM
also contains a standard set of configurations that we recommend for customer use.

PLL Locking Sequence
All of the flying-adder PLLs (except the DDR PLL) come-up in bypass mode at reset. All of the registers
(P, N, FREQ, and M) need to be programmed appropriately and then wait approximately 8 µs for
PLL_Audio and 5 µs for the other PLLS to be locked. Verification that the PLL is locked can be checked
by accessing the lock status bit in the PLL control register for each PLL (bit = 1 when the PLL is locked).
Once the PLL is locked, then the FA-PLL can be taken out of bypass mode. Control for bypass mode is
through chip-level registers. For more details on the PLL registers and bypass logic, see the PLL chapter
of the TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (SPRUGX8).

SYSCLKs
In some cases, the system clock inputs and PLL outputs are sent to the PRCM module for division and
multiplexing before being routed to the various device modules. These clock outputs from the PRCM
module are called SYSCLKs. Table 8-15 lists the main device SYSCLKs along with their maximum
supported clock frequencies. In addition, limits shown in the table may be further restricted by the clock
frequency limitations of the device modules using these clocks. For more details on module clock
frequency limits, see Section 8.3.6.

CLKOUT_MUX
The device includes one selectable general-purpose clock output (CLKOUT). The source for these output
clocks is controlled by the CLKOUT_MUX register in the control module and shown in Figure 8-9.

CLKOUT
Figure 8-9. CLKOUT Source Selection Logic
As shown in the figure, there are four possible sources for CLKOUT, one clock from each of the four
PLLs. The selected clock can be further divided by any ratio from 1 to 1/8 before going out on the
CLKOUT pin. The default selection is to select main PLL clock5, divider set to 1/1, and clock disabled.

Cortex™-A8 Interrupts
The Cortex™-A8 Interrupt Controller (AINTC) takes ARM device interrupts and maps them to either the
interrupt request (IRQ) or fast interrupt request (FIQ) of the ARM with an individual priority level. The
AINTC interrupts must be active low-level interrupts.
The AINTC is responsible for prioritizing all service requests from the system peripherals directed to the
Cortex™-A8 SS and generating either nIRQ or nFIQ to the host. The type of the interrupt (nIRQ or nFIQ)
and the priority of the interrupt inputs are programmable. It has the capability to handle up to 128 requests
which can be steered or prioritized as nFIQ or nIRQ interrupt requests.
The general features of the AINTC are:
• Up to 128 level-sensitive interrupts inputs
• Individual priority for each interrupt input
• Each interrupt can be steered to nFIQ or nIRQ
• Independent priority sorting for nFIQ and nIRQ.

C674x Interrupts
The C674x DSP interrupt controller is contained within the C674x module itself. This controller includes an
event combiner, interrupt selector, exception combiner, and advanced event generator which allow a large
number of system interrupts to be routed to its 12 maskable interrupts, grouped together for an exception
input or used as an event trigger.
The controller combines device events into 12 CPU interrupts. It also controls the generation of the CPU
exception and emulation interrupts and the generation of AEG events. The C674x interrupt controller
captures all events on the rising-edge. (C674x interrupt inputs must be active high pulse interrupts.) On
the device, only the level interrupts of the IP blocks are used and are converted into pulse interrupts by
chip-level logic before connection to the C674x interrupt inputs.
Within the C674x interrupt controller, the interrupt selector contains registers that allow the user to
program the source for each of 12 CPU interrupts. Some of the event sources come from within the
C674x module itself.
Table 8-20 shows the connection of device interrupts to the C674x. Shaded entries are hard coded within
the C674x module and cannot be changed.

NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects must be
taken into account. A transmission line with a delay of 2 ns can be used to produce the desired transmission line effect. The transmission line is
intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.

The load capacitance value stated is only for characterization and measurement of AC timing signals. This
load capacitance value does not indicate the maximum load the device is capable of driving.

1.8-V and 3.3-V Signal Transition Levels
All input and output timing parameters are referenced to Vref for both "0" and "1" logic levels. For 3.3-V IO,
Vref = 1.5 V. For 1.8-V IO, Vref = 0.9 V.

Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routings. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing or decreasing such delays. TI recommends utilizing the available IO buffer
information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS
models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing
Analysis application report (literature number SPRA839). If needed, external logic hardware such as
buffers may be used to compensate any timing differences.
For the DDR2 and DDR3, PCIe, SATA, USB, and HDMI interfaces, IBIS models are not used for timing
specification. TI provides, in this document, a PCB routing rule solution for each interface that describes
the routing rules used to ensure the interface timings are met. Video DAC guidelines (Section 9.10.2) are
also included to discuss important layout considerations.
9.2
Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner.

This section provides the timing specification for the DDR2 interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. These rules, when followed, result in a reliable DDR2 memory system without the need
for a complex timing closure process. For more information regarding the guidelines for using this DDR2
specification, see Understanding TI’s PCB Routing Rule-Based DDR2 Timing Specification Application
Report (SPRAAV0).

9.3.1.2.1 DDR2 Interface Schematic
Figure 9-5 shows the DDR2 interface schematic for a x32 DDR2 memory system. In Figure 9-6 the x16
DDR2 system schematic is identical except that the high-word DDR2 device is deleted.
When not using a DDR2 interface, the proper method of handling the unused pins is to tie off the DQS
pins by pulling the non-inverting DQS pin to the DDR_1V8 supply via a 1k-Ω resistor and pulling the
inverting DQS pin to ground via a 1k-Ω resistor. This needs to be done for each byte not used. Also,
include the 50-Ω pulldown for DDR[x]_VTP. All other DDR interface pins can be left unconnected. Note
that the supported modes for use of the DDR EMIF are 32 bits wide, 16 bits wide, or not used.

Figure 9-7 shows the required placement for the processor as well as the DDR2 devices. The dimensions
for this figure are defined in Table 9-5. The placement does not restrict the side of the PCB on which the
devices are mounted. The ultimate purpose of the placement is to limit the maximum trace lengths and
allow for proper routing space. For a 16-bit DDR memory system, the high-word DDR2 device is omitted
from the placement.

9.3.1.2.5 DDR2 Keepout Region
The region of the PCB used for the DDR2 circuitry must be isolated from other signals. The DDR2
keepout region is defined for this purpose and is shown in Figure 9-8. The size of this region varies with
the placement and DDR routing. Additional clearances required for the keepout region are shown in
Table 9-5.

Figure 9-8. DDR2 Keepout Region
NOTE
The region shown in should encompass all the DDR2 circuitry and varies depending on
placement. Non-DDR2 signals should not be routed on the DDR signal layers within the
DDR2 keepout region. Non-DDR2 signals may be routed in the region, provided t hey are
routed on layers separated from DDR2 signal layers by a ground layer. No breaks should be
allowed in the reference ground layers in this region. In addition, the 1.8V power plane
should cover the entire keepout region. Routes for the two DDR interfaces must be
separated by at least 4x; the more separation, the better.
9.3.1.2.6 Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR2 and other circuitry.
Table 9-6 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the DDR2 interfaces and DDR2 device. Additional bulk
bypass capacitance may be needed for other circuitry.

High-speed (HS) bypass capacitors are critical for proper DDR2 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, processor DDR power,
and processor DDR ground connections. Table 9-7 contains the specification for the HS bypass capacitors
as well as for the power connections on the PCB.

data lines to reduce EMI risk; however, serial terminations are the only type permitted. ODT's are
integrated on the data byte net classes. They should be enabled to ensure signal integrity.Table 9-10

9.3.1.2.10 VREFSSTL_DDR Routing
VREFSSTL_DDR is used as a reference by the input buffers of the DDR2 memories as well as the
processor. VREF is intended to be half the DDR2 power supply voltage and should be created using a
resistive divider as shown in Figure 9-6. Other methods of creating VREF are not recommended. Figure 99 shows the layout guidelines for VREF.

A 16-bit DDR memory system has two sets of data net classes; one for data byte 0, and one for data byte 1, each with an associated
DQS (2 DQSs) per DDR EMIF used.
A 32-bit DDR memory system has four sets of data net classes; one each for data bytes 0 through 3, and each associated with a DQS
(4 DQSs) per DDR EMIF used.
There is no need, and it is not recommended, to skew match across data bytes; that is, from DQS0 and data byte 0 to DQS1 and data
byte 1.

This specification only covers TMS320DM816x processor PCB designs that utilize DDR3 memory.
Designs using DDR2 memory should use the PCB design specifications for DDR2 memory in
Section 9.3.1. While similar, the two memory systems have different requirements. It is currently not
possible to design one PCB that covers both DDR2 and DDR3.

This table is per EMIF.
Two DDR3 devices are mirrored when one device is placed on the top of the board and the second device is placed on the bottom of
the board.
This is two mirrored pairs of DDR3 devices.
9.3.2.2.1 DDR3 EMIFs
The processor contains two separate DDR3 EMIFs. This specification covers one of these EMIFs
(DDR[0]) and, thus, needs to be implemented twice, once for each EMIF. The PCB layout generally turns
out to be a semi-mirror with DDR[1] being a flipped version of DDR[0]; the only exception being the DDR3
devices themselves are not flipped unless mounted on opposite sides of the PCB. Requirements are
identical between the two EMIFs.
9.3.2.3
DDR3 Interface Schematic
9.3.2.3.1 32-Bit DDR3 Interface
The DDR3 interface schematic varies, depending upon the width of the DDR3 devices used and the width
of the bus used (16 or 32 bits). General connectivity is straightforward and very similar. 16-bit DDR
devices look like two 8-bit devices. Figure 9-13 and Figure 9-14 show the schematic connections for 32-bit
interfaces using x16 devices.
9.3.2.3.2 16-Bit DDR3 Interface
Note that the 16-bit wide interface schematic is practically identical to the 32-bit interface (see Figure 9-13
and Figure 9-14); only the high-word DDR memories are removed and the unused DQS inputs are tied off.
The processor DDR[x]_DQS[2] and DDR[x]_DQS[3] pins should be pulled to the DDR supply via 1-kΩ
resistors. Similarly, the DDR[x]_DQS[2] and DDR[x]_DQS[3] pins should be pulled to ground via 1-kΩ
resistors.
When not using a DDR interface, the proper method of handling the unused pins is to tie off the DQS pins
by pulling the non-inverting DQS pin to the DDR_1V5 supply via a 1k-Ω resistor and pulling the inverting
DQSn pin to ground via a 1k-Ω resistor. This needs to be done for each byte not used. Also, include the
50-Ω pulldown for DDR[x]_VTP. All other DDR interface pins can be left unconnected. Note that the
supported modes for use of the DDR EMIF are 32 bits wide, 16 bits wide, or not used.

DDR3 speed grade depends on desired clock rate. Data rate is 2x the clock rate. For DDR3-1600, the clock rate is 800 MHz.
For valid DDR3 device configurations and device counts, see Section 9.3.2.3, Figure 9-13, and Figure 9-14.
9.3.2.5
PCB Stackup
The minimum stackup for routing the DDR3 interface is a four-layer stack up as shown in Table 9-16.
Additional layers may be added to the PCB stackup to accommodate other circuitry, enhance SI and EMI
performance, or to reduce the size of the PCB footprint. A six-layer stackup is shown in Table 9-17.
Complete stackup specifications are provided in Table 9-18.

Ground reference layers are preferred over power reference layers. Be sure to include bypass caps to accommodate reference layer
return current as the trace routes switch routing layers.
No traces should cross reference plane cuts within the DDR routing region. High-speed signal traces crossing reference plane cuts
create large return current paths which can lead to excessive crosstalk and EMI radiation.
Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available
for power routing. An 18-mil pad is required for minimum layer count escape.
For the DDR3 device BGA pad size, see the DDR3 device manufacturer documentation.
Z is the nominal singled-ended impedance selected for the PCB specified by item 13.

Placement
Figure 9-15 shows the required placement for the processor as well as the DDR3 devices. The
dimensions for this figure are defined in Table 9-19. The placement does not restrict the side of the PCB
on which the devices are mounted. The ultimate purpose of the placement is to limit the maximum trace
lengths and allow for proper routing space. For a 16-bit DDR memory system, the high-word DDR3
devices are omitted from the placement.

Non-DDR3 signals allowed within DDR3 keepout region provided they are separated from DDR3 routing layers by a ground plane.
Note that DDR3 signals from one DDR3 controller are considered non-DDR3 to the other controller. In other words, keep the two DDR3
interfaces separated by this specification.
9.3.2.7
DDR3 Keepout Region
The region of the PCB used for DDR3 circuitry must be isolated from other signals. The DDR3 keepout
region is defined for this purpose and is shown in Figure 9-16. The size of this region varies with the
placement and DDR routing. Additional clearances required for the keepout region are shown in Table 919. Non-DDR3 signals should not be routed on the DDR signal layers within the DDR3 keepout region.
Non-DDR3 signals may be routed in the region, provided they are routed on layers separated from the
DDR signal layers by a ground layer. No breaks should be allowed in the reference ground layers in this
region. In addition, the 1.5-V DDR3 power plane should cover the entire keepout region. Also note that the
two DDR3 controller's signals should be separated from each other by the specification in Table 9-19,
item 5.

Bulk Bypass Capacitors
Bulk bypass capacitors are required for moderate speed bypassing of the DDR3 and other circuitry.
Table 9-20 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note
that this table only covers the bypass needs of the DDR3 controllers and DDR3 devices. Additional bulk
bypass capacitance may be needed for other circuitry. Also note that Table 9-20 is per DDR3 controller;
thus, systems using both controllers have to meet the needs of Table 9-20 twice, once for each controller.

These devices should be placed near the devices they are bypassing, but preference should be given to the placement of the highspeed (HS) bypass capacitors and DDR3 signal routing.
9.3.2.9
High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critical for proper DDR3 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, processor DDR power,
and processor DDR ground connections. Table 9-21 contains the specification for the HS bypass
capacitors as well as for the power connections on the PCB. Generally speaking, it is good to:
1. Fit as many HS bypass capacitors as possible.
2. Minimize the distance from the bypass cap to the pins (balls) being bypassed.
3. Use the smallest physical sized capacitors possible with the highest capacitance readily available.
4. Connect the bypass capacitor pads to their vias using the widest traces possible and using the largest
hole size via possible.
5. Minimize via sharing. Note the limits on via sharing shown in Table 9-21.

9.3.2.9.1 Return Current Bypass Capacitors
Use additional bypass capacitors if the return current reference plane changes due to DDR3 signals
hopping from one signal layer to another. The bypass capacitor here provides a path for the return current
to hop planes along with the signal. As many of these return current bypass capacitors should be used as
possible. Since these are returns for signal current, the signal via size may be used for these capacitors.

9.3.2.11 DDR3 Signal Termination
Signal terminators are required for the CK and ADDR_CTRL net classes. The data lines are terminated by
ODT and, thus, the PCB traces should be unterminated. Detailed termination specifications are covered in
the routing rules in the following sections.
9.3.2.12 VREFSSTL_DDR Routing
VREFSSTL_DDR (VREF) is used as a reference by the input buffers of the DDR3 memories as well as
the processor. VREF is intended to be half the DDR3 power supply voltage and is typically generated with
the DDR3 1.5-V and VTT power supply. It should be routed as a nominal 20-mil wide trace with 0.1 µF
bypass capacitors near each device connection. Narrowing of VREF is allowed to accommodate routing
congestion.
9.3.2.13 VTT
Like VREF, the nominal value of the VTT supply is half the DDR3 supply voltage. Unlike VREF, VTT is
expected to source and sink current, specifically the termination current for the ADDR_CTRL net class
Thevinen terminators. VTT is needed at the end of the address bus and it should be routed as a power
sub-plane. VTT should be bypassed near the terminator resistors.

9.3.2.14 CK and ADDR_CTRL Topologies and Routing Definition
The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew
between them. CK is a bit more complicated because it runs at a higher transition rate and is differential.
The following subsections show the topology and routing for various DDR3 configurations for CK and
ADDR_CTRL. The figures in the following subsections define the terms for the routing specification
detailed in Table 9-24.
9.3.2.14.1 Four DDR3 Devices
Four DDR3 devices are supported on the DDR EMIF consisting of four x8 DDR3 devices arranged as one
bank (CS). These four devices may be mounted on a single side of the PCB, or may be mirrored in two
pairs to save board space at a cost of increased routing complexity and parts on the backside of the PCB.

9.3.2.16 Routing Specification
9.3.2.16.1 CK and ADDR_CTRL Routing Specification
Skew within the CK and ADDR_CTRL net classes directly reduces setup and hold margin and, thus, this
skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter
traces up to the length of the longest net in the net class and its associated clock. A metric to establish
this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the
length between the points when connecting them only with horizontal or vertical segments. A reasonable
trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address
Control Longest Manhattan distance.
Given the clock and address pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 9-37 and Figure 9-38 show
this distance for four loads and two loads, respectively. It is from this distance that the specifications on
the lengths of the transmission lines for the address bus are determined. CACLM is determined similarly
for other address bus configurations; that is, it is based on the longest net of the CK and ADDR_CTRL net
class. For CK and ADDR_CTRL routing, these specifications are contained in Table 9-24.

It is very likely that the longest CK and ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the
DDR3 memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net
class that satisfies this criteria and use as the baseline for CK and ADDR_CTRL skew matching and length control.
The length of shorter CK and ADDR_CTRL stubs as well as the length of the terminator stub are not included in this
length caculation. Non-included lengths are grayed out in the figure.
Assuming A8 is the longest, CALM = CACLMY + CACLMX + 300 mils.
The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8.

The use of vias should be minimized.
Additional bypass capacitors are required when using the DDR_1V5 plane as the reference plane to allow the return current to jump
between the DDR_1V5 plane and the ground plane when the net class swtiches layers at a via.
Non-mirrored configuration (all DDR3 memories on same side of PCB).
Mirrored configuration (one DDR3 device on top of the board and one DDR3 device on the bottom).
While this length can be increased for convienience, its length should be minimized.
ADDR_CTRL net class only (not CK net class). Minimizing this skew is recommended, but not required.
CK net class only.
CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes + 300 mils. For definition, see Section 9.3.2.16.1,
Figure 9-37, and Figure 9-38.

Center-to-center spacing is allowed to fall to minimum (w) for up to 1250 mils of routed length.
The ADDR_CTRL net class of the other DDR EMIF is considered other DDR3 trace spacing.
CK spacing set to ensure proper differential impedance.
Source termination (series resistor at driver) is specifically not allowed.
Termination values should be uniform across the net class.
9.3.2.16.2 DQS and DQ Routing Specification
Skew within the DQS, DQ and DM net classes directly reduces setup and hold margin and thus this skew
must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces
up to the length of the longest net in the net class and its associated clock. As with CK and ADDR_CTRL,
a reasonable trace route length is to within a percentage of its Manhattan distance. DQLMn is defined as
DQ Longest Manhattan distance n, where n is the byte number. For a 32-bit interface, there are four
DQLMs, DQLM0-DQLM3. Likewise, for a 16-bit interface, there are two DQLMs, DQLM0-DQLM1.
NOTE
It is not required, nor is it recommended, to match the lengths across all bytes. Length
matching is only required within each byte.
Given the DQS, DQ and DM pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 9-39 shows this distance for
four loads. It is from this distance that the specifications on the lengths of the transmission lines for the
data bus are determined. For DQS, DQ and DM routing, these specifications are contained in Table 9-25.

DB0 - DB3 represent data bytes 0 - 3.
There are four DQLMs, one for each byte (32-bit interface). Each DQLM is the longest Manhattan distance of the
byte; therefore:
DQLM0 = DQLMX0 + DQLMY0
DQLM1 = DQLMX1 + DQLMY1
DQLM2 = DQLMX2 + DQLMY2
DQLM3 = DQLMX3 + DQLMY3

External termination disallowed. Data termination should use built-in ODT functionality.
DQLMn is the longest Manhattan distance of a byte. For definition, see Section 9.3.2.16.2 and Figure 9-39.
DQLM0 is the longest Manhattan length for the net classes of Byte 0.
DQLM1 is the longest Manhattan length for the net classes of Byte 1.
DQLM2 is the longest Manhattan length for the net classes of Byte 2.
DQLM3 is the longest Manhattan length for the net slasses of Byte 3.
Length matching is only done within a byte. Length matching across bytes is neither required nor recommended.
Each DQS pair is length matched to its associated byte.
Center-to-center spacing is allowed to fall to minimum (w) for up to 1250 mils of routed length.
Other DDR3 trace spacing means other DDR3 net classes not within the byte.
This applies to spacing within the net classes of a byte.
DQS pair spacing is set to ensure proper differential impedance.

Emulation Features and Capability
Advanced Event Triggering (AET)
The device supports Advanced Event Triggering (AET). This capability can be used to debug complex
problems as well as understand performance characteristics of user applications. AET provides the
following capabilities:
• Hardware Program Breakpoints: specify addresses or address ranges that can generate events such
as halting the processor or triggering the trace capture.
• Data Watchpoints: specify data variable addresses, address ranges, or data values that can generate
events such as halting the processor or triggering the trace capture.
• Counters: count the occurrence of an event or cycles for performance monitoring.
• State Sequencing: allows combinations of hardware program breakpoints and data watchpoints to
precisely generate events for complex sequences.
For more information on AET, see the following documents:
• Using Advanced Event Triggering to Find and Fix Intermittent Real-Time Bugs application report
(literature number SPRA753)
• Using Advanced Event Triggering to Debug Real-Time Problems in High Speed Embedded
Microprocessor Systems application report (literature number SPRA387)
9.4.2
Trace
The device supports Trace at the Cortex™-A8, C674x, and System levels. Trace is a debug technology
that provides a detailed, historical account of application code execution, timing, and data accesses. Trace
collects, compresses, and exports debug information for analysis. The debug information can be exported
to the Embedded Trace Buffer (ETB), or to the 5-pin Trace Interface (system trace only). Trace works in
real-time and does not impact the execution of the system.
For more information on board design guidelines for Trace Advanced Emulation, see the Emulation and
Trace Headers Technical Reference Manual (literature number SPRU655).
9.4.3
IEEE 1149.1 JTAG
The JTAG (IEEE Standard 1149.1-1990 Standard-Test-Access Port and Boundary Scan Architecture)
interface is used for BSDL testing and emulation of the device. The TRST pin only needs to be released
when it is necessary to use a JTAG controller to debug the device or exercise the device's boundary scan
functionality. For maximum reliability, the device includes an internal pulldown (IPD) on the TRST pin to
ensure that TRST is always asserted upon power up and the device's internal emulation logic is always
properly initialized. JTAG controllers from Texas Instruments actively drive TRST high. However, some
third-party JTAG controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the device after powerup and externally
drive TRST high before attempting any emulation or boundary-scan operations.
The main JTAG features include:
• 32KB embedded trace buffer (ETB)
• 5-pin system trace interface for debug
• Supports Advanced Event Triggering (AET)
• All processors can be emulated via JTAG ports
• All functions on EMU pins of the device:
– EMU[1:0] - cross-triggering, boot mode (WIR), STM trace
– EMU[4:2] - STM trace only (single direction)
– EMU[2] - only valid pin to use as clock

IEEE 1149.7 cJTAG
Besides the standard (legacy) JTAG mode of operation, the target debug interface can also be switched to
a compressed JTAG (cJTAG) mode of operation, commonly referred to as IEEE1149.7 standard. An
IEEE1149.7 adapter module runs a 2-pin communication protocol on top of an IEEE1149.1 JTAG TAP.
The debug-IP logic serializes the IEEE1149.1 transactions, using a variety of compression formats, to
reduce the number of pins needed to implement a JTAG debug port. This device implements only a
subset of the IEEE1149.7 protocol; it supports Class 0 and Class 1 operation. On this device the cJTAG
ID[7:0] is tied to 0x00.
NOTE
The default setting of the scan port is IEEE 1149.1. A cJTAG emulator connected only to
TCLK and TMS can re-configure the port to cJTAG by scanning in a special command
sequence. For the scan sequence required to switch modes, see the IEEE1149.7
specification.

Enhanced Direct Memory Access (EDMA) Controller
The EDMA controller handles all data transfers between memories and the device slave peripherals on
the device. These data transfers include cache servicing, non-cacheable memory accesses, userprogrammed data transfers, and host accesses.
9.5.1
EDMA Channel Synchronization Events
The EDMA channel controller supports up to 64 channels that service peripherals and memory. Each
EDMA channel is mapped to a default EDMA synchronization event as shown in Table 9-34. By default,
each event uses the parameter entry that matches its event number. However, because the device
includes a channel mapping feature, each event may be mapped to any of 512 parameter table entries.
For more detailed information on the EDMA module and how EDMA events are enabled, captured,
processed, linked, chained, and cleared, see the EDMA chapter in the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (literature number SPRUGX8).

SPRS614F – MARCH 2011 – REVISED MARCH 2015
Ethernet Media Access Controller (EMAC)
The device includes two Ethernet Media Access Controller (EMAC) modules which provide an efficient
interface between the device and the networked community. The EMAC supports 10Base-T (10 Mbits per
second [Mbps]) and 100Base-TX (100 Mbps) in either half- or full-duplex mode, and 1000Base-T (1000
Mbps) in full-duplex mode, with hardware flow control and quality-of-service (QOS) support. The EMAC
controls the flow of packet data from the device to an external PHY. A single MDIO interface is pinned out
to control the PHY configuration and status monitoring. Multiple external PHYs can be controlled by the
MDIO interface.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the Carrier Sense Multiple
Access with Collision Detection (CSMA/CD) Access Method and Physical Layer specifications. The IEEE
802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviating from this standard, the EMAC module does not use the transmit coding error signal, MTXER.
Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC
intentionally generates an incorrect checksum by inverting the frame CRC so that the transmitted frame is
detected as an error by the network. In addition, the EMAC IOs operate at 3.3 V and are not compatible
with 2.5-V IO signaling; therefore, only Ethernet PHYs with 3.3-V IO interface should be used. The EMAC
module incorporates 8K bytes of internal RAM to hold EMAC buffer descriptors and contains the
necessary components to enable the EMAC to make efficient use of device memory and control device
interrupts.
The EMAC module on the device supports two interface modes: Media Independent Interface (MII) and
Gigabit Media Independent Interface (GMII). The MII and GMII interface modes are defined in the IEEE
802.3-2002 standard. The EMAC uses the same pins for the MII and GMII modes of operation. Only one
mode can be used at a time.
The MII and GMII modes-of-operation pins are as follows:
• MII:
EMAC[1:0]_TXCLK,
EMAC[1:0]_RXCLK,
EMAC[1:0]_TXD[3:0],
EMAC[1:0]_RXD[3:0],
EMAC[1:0]_TXEN, EMAC[1:0]_RXDV, EMAC[1:0]_RXER, EMAC[1:0]_COL, EMAC[1:0]_CRS,
MDIO_MCLK, and MDIO_MDIO.
• GMII:
EMAC[1:0]_GMTCLK,
EMAC[1:0]_TXCLK,
EMAC[1:0]_RXCLK,
EMAC[1:0]_TXD[7:0],
EMAC[1:0]_RXD[7:0], EMAC[1:0]_TXEN, EMAC[1:0]_RXDV, EMAC[1:0]_RXER, EMAC[1:0]_COL,
EMAC[1:0]_CRS, MDIO_MCLK, and MDIO_MDIO.
For more detailed information on the EMAC module, see the EMAC and MDIO chapter in the
TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (literature number
SPRUGX8).

Management Data Input and Output (MDIO)
The Management Data Input and Output (MDIO) module continuously polls all 32 MDIO addresses in
order to enumerate all PHY devices in the system.
The MDIO module implements the 802.3 serial management interface to interrogate and control Ethernet
PHYs using a shared two-wire bus. Host software uses the MDIO module to configure the autonegotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and configure
required parameters in the EMAC module for correct operation. The module is designed to allow almost
transparent operation of the MDIO interface, with very little maintenance from the core processor. A single
MDIO interface is pinned out to control the PHY configuration and status monitoring. Multiple external
PHYs can be controlled by the MDIO interface.
For more detailed information on the MDIO peripheral, see the EMAC and MDIO chapter in the
TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (literature number
SPRUGX8).

General-Purpose Input and Output (GPIO)
The GPIO peripheral provides general-purpose pins that can be configured as either inputs

modes. The GPIO peripheral provides generic connections to external devices.
or outputs.
output pin.
an internal
generation
The device contains two GPIO modules and each GPIO module is made up of 32 identical channels.
The device GPIO peripheral supports the following:
• Up to 64 3.3-V GPIO pins, GP0[31:0] and GP1[31:0] (the exact number available varies as a function
of the device configuration). Each channel can be configured to be used in the following applications:
– Data input and output
– Keyboard interface with a de-bouncing cell
– Synchronous interrupt generation (in active mode) upon the detection of external events (signal
transitions or signal levels).
• Synchronous interrupt requests from each channel are processed by two identical interrupt generation
sub-modules to be used independently by the ARM or DSP. Interrupts can be triggered by rising or
falling edge, specified for each interrupt-capable GPIO signal.
• Shared registers can be accessed through "Set & Clear" protocol. Software writes 1 to corresponding
bit positions to set or to clear GPIO signals. This allows multiple software processes to toggle GPIO
output signals without critical section protection (disable interrupts, program GPIO, re-enable interrupts,
to prevent context switching to another process during GPIO programming).
• Separate input and output registers.
• Output register in addition to set or clear so that, if preferred by software, some GPIO output signals
can be toggled by direct write to the output registers.
• Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status and open-drain IO cell, allows wired logic to be implemented.
For more detailed information on GPIOs, see the GPIO chapter in the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (literature number SPRUGX8).

SPRS614F – MARCH 2011 – REVISED MARCH 2015
General-Purpose Memory Controller (GPMC) and Error Locator Module (ELM)
The GPMC is a device memory controller used to provide a glueless interface to external memory devices
such as NOR Flash, NAND Flash (with BCH and Hamming Error Code Detection for 8-bit or 16-bit NAND
Flash), SRAM, and Pseudo-SRAM. It includes flexible asynchronous protocol control for interface to
SRAM-like memories and custom logic (FPGA, CPLD, ASICs, and others).
The first section of GPMC memory (0x0 - 0x00FF_FFFF) is reserved for BOOTROM. Accessible memory
starts at location 0x0100_0000.
Other supported features include:
• 8-bit and 6-bit wide multiplexed address and data bus
• Up to 6 chip selects with up to 256M-byte address space per chip select pin
• Non-multiplexed address and data mode
• Pre-fetch and write posting engine associated with system DMA to get full performance from NAND
device with minimum impact on NOR and SRAM concurrent access.
The device also contains an Error Locator Module (ELM) which is used to extract error addresses from
syndrome polynomials generated using a BCH algorithm. Each of these polynomials gives a status of the
read operations for a 512 bytes block from a NAND flash and its associated BCH parity bits, plus
optionally spare area information. The ELM has the following features:
• 4-bit, 8-bit, and 16-bit per 512-byte block error location based on BCH algorithms
• Eight simultaneous processing contexts
• Page-based and continuous modes
• Interrupt generation on error location process completion
– When the full page has been processed in page mode
– For each syndrome polynomial in continuous mode.
For more detailed information on the GPMC, see the GPMC chapter in the TMS320DM816x DaVinci
Digital Media Processors Technical Reference Manual (literature number SPRUGX8).

J = GPMC_FCLK period.

For burst read: A = (CSRdOffTime - CSOnTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK period [n

For single read: C = RdCycleTime * (TimeParaGranularity + 1) * GPMC_FCLK

M = ( RdCycleTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK.
Parameter M expression is given as one example of GPMC programming. The IO DIR signal goes from IN to OUT after both
RdCycleTime and BusTurnAround completion. Behavior of the IO direction signal depends on the kind of successive read and write
accesses performed to the memory and multiplexed or non-multiplexed memory addressing scheme, whether the bus keeping feature is
enabled or not. The IO DIR behavior is automatically handled by the GPMC controller.

HDMI Interface Design Specifications
NOTE
For more information on PCB layout, see the DM816xx Easy CYG Package PCB Escape
Routing application report (literature number SPRABK6).
This section provides PCB design and layout specifications for the HDMI interface. The design rules
constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. Simulation and
system design work has been done to ensure the HDMI interface requirements are met.
9.9.1.1
HDMI Interface Schematic
The HDMI bus is separated into three main sections:
1. Transition Minimized Differential Signaling (TMDS) high-speed digital video interface
2. Display Data Channel (I2C bus for configuration and status exchange between two devices)
3. Consumer Electronics Control (optional) for remote control of connected devices.
The DDC and CEC are low-speed interfaces, so nothing special is required for PCB layout of these
signals. Their connection is shown in Figure 9-66.
The TMDS channels are high-speed differential pairs and, therefore, require the most care in layout.
Specifications for TMDS layout are below.

9.9.1.2
TMDS Routing
The TMDS signals are high-speed differential pairs. Care must be taken in the PCB layout of these signals
to ensure good signal integrity.
The TMDS differential signal traces must be routed to achieve 100 Ω (±10%) differential impedance and
60 Ω (±10%) single-ended impedance. Single-ended impedance control is required because differential
signals are extremely difficult to closely couple on PCBs and, therefore, single-ended impedance becomes
important.
These impedances are impacted by trace width, trace spacing, distance to reference planes, and dielectric
material. Verify with a PCB design tool that the trace geometry for both data signal pairs results in as
close to 60 Ω impedance traces as possible. For best accuracy, work with your PCB fabricator to ensure
this impedance is met.
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations do not affect impedance as much; therefore, it
is easier to maintain an accurate impedance over the length of the signal. The wider traces also show
reduced skin effect and, therefore, often result in better signal integrity.
Table 9-62 shows the routing specifications for the TMDS signals.

9.9.1.3
DDC Signals
As shown in Figure 9-66, the DDC connects just like a standard I2C bus. As such, resistor pullups must
be used to pull up the open drain buffer signals unless they are integrated into the ESD protection chip
used. If used, these pullup resistors should be connected to a 3.3-V supply.
9.9.1.4
HDMI ESD Protection Device (Required)
Interfaces that connect to a cable such as HDMI generally require more ESD protection than can be built
into the processor's outputs. Therefore, this HDMI interface requires the use of an ESD protection chip to
provide adequate ESD protection and to translate I2C voltage levels from the 3.3 V supplied by the device
to the 5 volts required by the HDMI specification.
When selecting an ESD protection chip, choose the lowest capacitance ESD protection available to
minimize signal degradation. In no case should the ESD protection circuit capacitance be more than 5 pF.
TI manufactures devices that provide ESD protection for HDMI signals such as the TPD12S521. For more
information see the www.ti.com website.

9.10 High-Definition Video Processing Subsystem (HDVPSS)
The device High-Definition Video Processing Subsystem (HDVPSS) provides a video input interface for
external imaging peripherals (that is, image sensors, video decoders, and others) and a video output
interface for display devices, such as analog SDTV displays, analog and digital HDTV displays, and digital
LCD panels. It includes HD and SD video encoders, and an HDMI transmitter interface.
The device HDVPSS features include:
• High quality (HD) and medium quality (SD) display processing pipelines with de-interlacing, scaling,
noise reduction, alpha blending, chroma keying, color space conversion, flicker filtering, and pixel
format conversion.
• HD and SD compositor features for PIP support.
• Format conversions (up to 1080p 60 Hz) include scan format conversion, scan rate conversion, aspectratio conversion, and frame size conversion.
• Supports additional video processing capabilities by using the subsystem's memory-to-memory feature.
• Two parallel video processing pipelines support HD (up to 1080p60) and SD (NTSC and PAL)
simultaneous outputs.
– HD analog component output with OSD and embedded timing codes (BT.1120)
• 3-channel HD-DAC with 12-bit resolution.
• External HSYNC and VSYNC signals available on silicon revision 2.x devices. For more details,
see below.
– SD analog output with OSD with embedded timing codes (BT.656)
• Simultaneous component, S-video and composite
• 4-channel SD-DAC with 10-bit resolution
• Options available to support MacroVision and CGMS-A (contact local TI Sales rep for
information).
– Digital HDMI 1.3a compliant transmitter (for details, see Section 9.9, High-Definition Multimedia
Interface (HDMI)).
• Up to two (one 16-bit, 24-bit, 30-bit and one 16-bit) digital video outputs (up to 165 MHz).
– VOUT[0] can output up to 30-bit video and supports RGB, YUV444, Y and C and BT.656 modes.
– VOUT[1] can output up to 16-bit video and supports Y and C and BT.656 modes.
• Two (one 16-bit, 24-bit and one 16-bit) independently configurable external video input capture ports
(up to 165 MHz).
– 16-bit and 24-bit HD digital video input or dual clock independent 8-bit SD inputs on each capture
port.
• VIN[0] can accept single-channel 16-bit, 24-bit (YCbCr and RGB) video or dual-channel 8-bit
(YCbCr) video.
• VIN[1] can accept single-channel 16-bit (YCbCr) video or dual-channel 8-bit (YCbCr) video.
– Embedded sync and external sync modes are supported for all input configurations.
– De-multiplexing of both pixel-to-pixel and line-to-line multiplexed streams, effectively supporting up
to 16 simultaneous SD inputs with a glueless interface to an external multiplexer such as the
TVP5158.
– Additional features include: programmable color space conversion, scaler and chroma
downsampler, ancillary VANC and VBI data capture (decoded by software), noise reduction.

Availability of a combination of these digital video input and output port configurations, control signals
for multiple 8-bit ports, as well as separate synchronization signals is limited by the device pin
multiplexing (for details, see Section 6.5). The following video inputs and outputs are not multiplexed
and are always available:
– SD DAC composite, S-video, component out
– HD DAC component out
– HDMI output (same as VOUT[1])
– 16-bit VOUT[0] (embedded sync)
– Single 16-bit, dual 8-bit VIN[0] (embedded sync).
Graphics features:
– Three independently-generated graphics layers.
– Each supports full-screen resolution graphics in HD, SD or both.
– Up and down scaler optimized for graphics.
– Global and pixel-level alpha blending supported.
Discrete external HSYNC and VSYNC signals for the HD-DAC are available on silicon revision 2.x
devices. These signals are mapped to the following pins (for details, see Section 4.2.20):
– HSYNC - AR5, AT9, AR8
– VSYNC - AL5, AP9, AL9
The functionality of these pins is set using the SPARE_CTRL0 register (address: 0x4814 0724).
Figure 9-67 and Table 9-70 describe the SPARE_CTRL0 register.
Note: When changing this register, read original value and write back same value in Reserved
fields.
For example, these are the steps required to use the pins AR8 and AL9 as the DAC_HSYNC and
VSYNC signals:
1. Set the PINCTRLx registers for AR8 and AL9 as follows:
• 0x4814 0894 = 0x00000001
• 0x4814 0898 = 0x00000001
2. Select analog VENC sync out option as follows:
• 0x4814 0724 = 0x00000004

9.10.2 Video DAC Guidelines and Electrical Data and Timing
The device's analog video DAC outputs are designed to drive a 37.5-Ω load. Figure 9-71 describes a
typical circuit that permits connecting the analog video output from the device to standard 75-Ω impedance
video systems. The device requires the use of a buffer to drive the actual video outputs, so one solution is
to use a video amplifier with integrated buffer and internal filter, such as the Texas Instruments THS7360,
which provides a complete solution for the typical output circuit shown in Figure 9-71.

Figure 9-71. Typical Output Circuits for Analog Video from DACs
During board design, the onboard traces and parasitics must be matched for the channel. The video DAC
output pin (IOUTx) is a very high-frequency analog signal and must be routed with extreme care. As a
result, the path of this signal must be as short as possible, and as isolated as possible from other
interfering signals. The load resistor and amplifier or buffer should be placed close together and as close
as possible to the device pins. Other layout guidelines include:
• Take special care to bypass the DAC power supply pin with a capacitor.
• Place the 75-Ω resistor as close as possible (<0.5") to the amplifier or buffer (THS7360) output pin.
• To maintain a high quality video signal, 75-Ω (±10%) characteristic impedance traces should be used
after the 75-Ω series resistor.
• Minimize input trace lengths to the device to reduce parasitic capacitance.
• Include solid ground return paths.
• Match trace lengths as close as possible within a video format group (that is, Y, Pb, and Pr for
component output, and Y and C for s-video output should match each other).
For additional video DAC design guidelines, see the HDVPSS chapter in the TMS320DM816x DaVinci
Digital Media Processors Technical Reference Manual (literature number SPRUGX8).

9.12 Multichannel Audio Serial Port (McASP)
The multichannel audio serial port (McASP) functions as a general-purpose audio serial port optimized for
the needs of multichannel audio applications. The McASP is useful for time-division multiplexed (TDM)
stream, Inter-Integrated Sound (I2S) protocols, and intercomponent digital audio interface transmission
(DIT).
9.12.1 McASP Device-Specific Information
The device includes three multichannel audio serial port (McASP) interface peripherals (McASP0,
McASP1, and McASP2). The McASP module consists of a transmit and receive section. These sections
can operate completely independently with different data formats, separate master clocks, bit clocks, and
frame syncs or, alternatively, the transmit and receive sections may be synchronized. The McASP module
also includes shift registers that may be configured to operate as either transmit data or receive data. The
transmit section of the McASP can transmit data in either a time-division-multiplexed (TDM) synchronous
serial format or in a digital audio interface (DIT) format where the bit stream is encoded for SPDIF, AES-3,
IEC-60958, CP-430 transmission. The receive section of the McASP peripheral supports the TDM
synchronous serial format.
The McASP module can support one transmit data format (either a TDM format or DIT format) and one
receive format at a time. All transmit shift registers use the same format and all receive shift registers use
the same format; however, the transmit and receive formats need not be the same. Both the transmit and
receive sections of the McASP also support burst mode, which is useful for non-audio data (for example,
passing control information between two devices).
The McASP peripheral has additional capability for flexible clock generation and error detection and
handling, as well as error management.
The device McASP0 module has six serial data pins, while McASP1 and McASP2 are limited to two serial
data pins each.
The McASP FIFO size is 256 bytes and two DMA and two interrupt requests are supported. Buffers are
used transparently to better manage DMA, which can be leveraged to manage data flow more efficiently.
For more detailed information on and the functionality of the McASP peripheral, see the McASP chapter in
the TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (literature number
SPRUGX8).

9.13 Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (AD) and digital-to-analog (DA) devices
• Supports TDM, I2S, and similar formats
• External shift clock or an internal, programmable frequency shift clock for data transfer
• 5KB Tx and Rx buffer
• Supports three interrupt and two DMA requests.
The McBSP module may support two types of data transfer at the system level:
• The full-cycle mode, for which one clock period is used to transfer the data, generated on one edge
and captured on the same edge (one clock period later).
• The half-cycle mode, for which one half clock period is used to transfer the data, generated on one
edge and captured on the opposite edge (one half clock period later). Note that a new data is
generated only every clock period, which secures the required hold time. The interface clock (CLKX or
CLKR) activation edge (data or frame sync capture and generation) has to be configured accordingly
with the external peripheral (activation edge capability) and the type of data transfer required at the
system level.
For more detailed information on the McBSP peripheral, see the McBSP chapter in the TMS320DM816x
DaVinci Digital Media Processors Technical Reference Manual (literature number SPRUGX8).
The following sections describe the timing characteristics for applications in normal mode (that is, the
McBSP connected to one peripheral) and TDM applications in multipoint mode.
9.13.1 McBSP Peripheral Registers
This McBSP peripheral registers are described in the TMS320DM816x DaVinci Digital Media Processors
Technical Reference Manual (literature number SPRUGX8). Each register is documented as an offset
from a base address for the peripheral. The base addresses for all of the peripherals are shown in
Table 3-26, L3 Memory Map.

• Automatic credit management
• ECRC generation and checking
• Configurable BAR filtering
• Supports PCIe messages
• Legacy interrupt reception (RC) and generation (EP)
• MSI generation and reception
• PCI device power management, except D3 cold with vaux
• Active state power management state L0 and L1.
For more detailed information on the PCIe port peripheral module, see the PCIe chapter in the
TMS320DM816x DaVinci Digital Media Processors Technical Reference Manual (literature number
SPRUGX8).
The PCIe peripheral on the device conforms to the PCI Express Base 2.0 Specification.
9.14.1 PCIe Design and Layout Specifications
NOTE
For more information on PCB layout, see the DM816xx Easy CYG Package PCB Escape
Routing application report (literature number SPRABK6).
9.14.1.1 Clock Source
A standard 100-MHz PCIe differential clock source must be used for PCIe operation (for details, see
Section 8.3.2).
9.14.1.2 PCIe Connections and Interface Compliance
The PCIe interface on the device is compliant with the PCI Express Base 2.0 Specification. Refer to the
PCIe specifications for all connections that are described in it. For coupling capacitor selection, see
Section 9.14.1.2.1.
The use of PCIe-compatible bridges and switches is allowed for interfacing with more than one other
processor or PCIe device.
9.14.1.2.1 Coupling Capacitors
AC coupling capacitors are required on the transmit data pair. Table 9-85 shows the requirements for
these capacitors.

9.14.1.2.2 Polarity Inversion
The PCIe specification requires polarity inversion support. This means, for layout purposes, polarity is
unimportant since each signal can change its polarity on-die inside the chip. This means polarity within a
lane is unimportant for layout.
9.14.1.2.3 Lane Reversal
The device supports lane reversal. Since there are two lanes, this means the lanes can be switched in
layout for better PCB routing.
9.14.1.3 Non-Standard PCIe Connections
The following sections contain suggestions for any PCIe connection that is not described in the official
PCIe specification, such as an on-board device-to-device connection, or device-to-other PCIe-compliant

9.14.1.3.2 Routing Specifications
The PCIe data signal traces must be routed to achieve 100 Ω (±20%) differential impedance and 60 Ω
(±15%) single-ended impedance. The single-ended impedance is required because differential signals are
extremely difficult to closely couple on PCBs and, therefore, single-ended impedance becomes important.
These requirements are the same as those recommended in the PCIe Motherboard Checklist 1.0
document, available from PCI-SIG.
These impedances are impacted by trace width, trace spacing, distance between signals and referencing
planes, and dielectric material. Verify with a PCB design tool that the trace geometry for both data signal
pairs result in as close to 100 Ω differential impedance and 60 Ω single-ended impedance as possible. For
best accuracy, work with your PCB fabricator to ensure this impedance is met.

SPRS614F – MARCH 2011 – REVISED MARCH 2015
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations do not affect impedance as much; therefore, it
is easier to maintain an accurate impedance over the length of the signal. The wider traces also show
reduced skin effect and, therefore, often result in better signal integrity.

9.15 Real-Time Clock (RTC)
The real-time clock is a precise timer that can generate interrupts on intervals specified by the user.
Interrupts can occur every second, minute, hour, or day. The clock, itself, can track the passage of real
time for durations of several years, provided it has a sufficient power source the whole time.
The basic purpose for the RTC is to keep time of day. The other equally important purpose of the RTC is
for Digital Rights management. Some degree of tamper-proofing is needed to ensure that simply stopping,
resetting, or corrupting the RTC does not go unnoticed; so, if this occurs, the application can re-acquire
the time of day from a trusted source. The final purpose of RTC is to wake up the rest of the device from a
power-down state. The RTC features include:
• Time information (hours, minutes, seconds) directly in binary coded decimal (BCD), for easy decoding.
• Calendar information (day, month, year, day of week) directly in BCD code up to year 2099.
• Shadow time and calendar access; ease of reading time.
• Interrupt generation, periodically (1d, 1h, 1m, 1s) or at a precise time of day or date.
• 30-second time correction (crystal frequency compensation).
• OCP slave port for register access.
• Supports power idle protocol with SWakeUp capable on alarm or timer events.
The RTC is driven by SYSCLK18 (32.768 kHz) or an optional 32.768-kHz clock can be input on the
CLKIN32 clock input pin for RTC reference. If the CLKIN32 pin is not connected to a 32.768-kHz clock
input, this pin should be pulled low.
Figure 9-78 shows the major components of the RTC.

9.17 Serial ATA Controller (SATA)
The Serial ATA (SATA) peripheral provides a direct interface for up to two hard disk drives (SATA) and
supports the following features:
• Serial ATA 1.5 Gbps and 3 Gbps speeds
• Integrated PHY
• Integrated Rx and Tx data buffers
• Supports all SATA power management features
• Hardware-assisted native command queuing (NCQ) for up to 32 entries
• Supports port multiplier with command-based switching for connection to multiple hard disk drives
• Activity LED support.
For more detailed information on the SATA, see the SATA chapter in the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (literature number SPRUGX8).
9.17.1 SATA Interface Design Specifications
NOTE
For more information on PCB layout, see the DM816xx Easy CYG Package PCB Escape
Routing application report (literature number SPRABK6).
This section provides PCB design and layout specifications for the SATA interface. The design rules
constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. Simulation and
system design work has been done to ensure the SATA interface requirements are met.
A standard 100-MHz differential clock source must be used for SATA operation (for details, see
Section 8.3.2).
9.17.1.1 SATA Interface Schematic
Figure 9-83 shows the data portion of the SATA interface schematic. The specific pin numbers can be
obtained from Table 4-17, Serial ATA Terminal Functions.

9.17.1.4 Routing Specifications
The SATA data signal traces must be routed to achieve 100 Ω (±20%) differential impedance and 60 Ω
(±15%) single-ended impedance. The single-ended impedance is required because differential signals are
extremely difficult to closely couple on PCBs and, therefore, single-ended impedance becomes important.
60 Ω is chosen for the single-ended impedance to minimize problems caused by too low an impedance.
These impedances are impacted by trace width, trace spacing, distance to reference planes, and dielectric
material. Verify with a PCB design tool that the trace geometry for both data signal pairs results in as
close to 100 Ω differential impedance and 60 Ω single-ended impedance traces as possible. For best
accuracy, work with your PCB fabricator to ensure this impedance is met.
Table 9-97 shows the routing specifications for the SATA data signals.

SPRS614F – MARCH 2011 – REVISED MARCH 2015
9.18 Serial Peripheral Interface (SPI)
The SPI is a high-speed synchronous serial input and output port that allows a serial bit stream of
programmed length (4 to 32 bits) to be shifted into and out of the device at a programmed bit-transfer rate.
The SPI is normally used for communication between the device and external peripherals. Typical
applications include an interface-to-external IO or peripheral expansion via devices such as shift registers,
display drivers, SPI EEPROMs, and analog-to-digital converters (ADCs).
The SPI supports the following features:
• Master and slave operation
• Four chip selects for interfacing and control to up to four SPI slave devices and connection to a single
external master
• 32-bit shift register
• Buffered receive and transmit data register per channel (1 word deep), FIFO size is 64 bytes
• Programmable SPI configuration per channel (clock definition, enable polarity and word width)
• Supports one interrupt request and two DMA requests per channel.
For more detailed information on the SPI, see the SPI chapter in the TMS320DM816x DaVinci Digital
Media Processors Technical Reference Manual (literature number SPRUGX8).

This timing applies to all configurations regardless of SPI_CLK polarity and which clock edges are used to drive output data and capture
input data.
Related to the SPI_CLK maximum frequency.
Maximum frequency = 48 MHz
P = SPICLK period.
SPI_CLK phase is programmable with the PHA bit of the SPI_CH(i)CONF register.
B = (TCS + 0.5) * TSPICLKREF * Fratio, where TCS is a bit field of the SPI_CH(i)CONF register and Fratio = Even ≥2.
When P = 20.8 ns, A = (TCS + 1) * TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register. When P > 20.8 ns, A = (TCS
+ 0.5) * Fratio * TSPICLKREF, where TCS is a bit field of the SPI_CH(i)CONF register.
Maximum frequency = 24 MHz

9.19 Timers
The device has seven 32-bit general-purpose (GP) timers that have the following features:
• Timers 1-3 are for software use and do not have an external connection
• Dedicated input trigger for capture mode and dedicated output trigger or pulse width modulation
(PWM) signal
• Interrupts generated on overflow, compare, and capture
• Free-running 32-bit upward counter
• Supported modes:
– Compare and capture modes
– Auto-reload mode
– Start-stop mode
• Timer[7:1] functional clock is sourced from either the 27-MHz system clock, 32.768-kHz RTC clock or
the TCLKIN external timer input clock, as selected within the PRCM
• On-the-fly read and write register (while counting)
• Generates interrupts to the ARM and DSP CPUs.
The device has one system watchdog timer that has the following features:
• Free-running 32-bit upward counter
• On-the-fly read and write register (while counting)
• Reset upon occurrence of a timer overflow condition
• Two possible clock sources:
– Internal 32.768-kHz clock derived from 27-MHz system clock.
– External clock input on the CLKIN32 input pin.
The watchdog timer is used to provide a recovery mechanism for the device in the event of a fault
condition, such as a non-exiting code loop.
For more detailed information, see the Timers chapter in the TMS320DM816x DaVinci Digital Media
Processors Technical Reference Manual (literature number SPRUGX8).

9.20 Universal Asynchronous Receiver and Transmitter (UART)
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallelto-serial conversion on data received from the CPU. The device provides up to three UART peripheral
interfaces, depending on the selected pin multiplexing.
Each UART has the following features:
• Selectable UART, IrDA (SIR, MIR) and CIR modes
• Dual 64-entry FIFOs for received and transmitted data payload
• Programmable and selectable transmit and receive FIFO trigger levels for DMA and interrupt
generation
• Baud-rate generation based upon programmable divisors N (N=1…16384)
• Two DMA requests and one interrupt request to the system
• Can connect to any RS-232 compliant device.
UART functions include:
• Baud-rate up to 3.6 Mbps
• Programmable serial interfaces characteristics
– 5, 6, 7, or 8-bit characters
– Even, odd, or no parity-bit generation and detection
– 1, 1.5, or 2 stop-bit generation
– Flow control: hardware (RTS and CTS) or software (XON and XOFF)
• Additional modem control functions (UART0_DTR, UART0_DSR, UART0_DCD, and UART0_RIN) for
UART0 only; UART1 and UART2 do not support full-flow control signaling.
IR-IrDA functions include:
• Support of IrDA 1.4 slow infrared (SIR, baud-rate up to 115.2 Kbps), medium infrared (MIR, baud-rate
up to 1.152 Mbps) and fast infrared (FIR baud-rate up to 4.0 Mbps) communications
• Supports framing error, cyclic redundancy check (CRC) error, illegal symbol (FIR), and abort pattern
(SIR, MIR) detection

SPRS614F – MARCH 2011 – REVISED MARCH 2015
9.21 Universal Serial Bus (USB2.0)
The device includes two USB2.0 modules which support the Universal Serial Bus Specification Revision
2.0. The following are some of the major USB features that are supported:
• USB 2.0 peripheral at high speed (HS: 480 Mbps) and full speed (FS: 12 Mbps)
• USB 2.0 host at HS, FS, and low speed (LS: 1.5 Mbps)
• Each endpoint (other than endpoint 0, control only) can support all transfer modes (control, bulk,
interrupt, and isochronous)
• Supports high-bandwidth ISO mode
• Supports 16 Transmit (TX) and 16 Receive (RX) endpoints including endpoint 0
• FIFO RAM - 32K endpoint - Programmable size
• Includes two integrated PHYs; requires a low-jitter 24-MHz source clock for its PLL
• RNDIS-like mode for terminating RNDIS-type protocols without using short-packet termination for
support of MSC applications.
The USB2.0 modules do not support the following features:
• On-chip charge pump (VBUS power must be generated external to the device)
• RNDIS mode acceleration for USB sizes that are not multiples of 64 bytes
• Endpoint max USB packet sizes that do not conform to the USB2.0 spec (for FS and LS: 8, 16, 32, 64,
and 1023 are defined; for HS: 64, 128, 512, and 1024 are defined).
For more detailed information on the USB2.0 peripheral, see the USB2.0 chapter in the TMS320DM816x
DaVinci Digital Media Processors Technical Reference Manual (literature number SPRUGX8). For
detailed information on USB board design and layout guidelines, see the USB 2.0 Board Design and
Layout Guidelines application report (literature number SPRAAR7). For general information on PCB
layout, see the DM816xx Easy CYG Package PCB Escape Routing application report (literature number
SPRABK6).

10 Device and Documentation Support
10.1 Device Support
10.1.1 Development Support
TI offers an extensive line of development tools, including tools to evaluate the performance of the
processors, generate code, develop algorithm implementations, and fully integrate and debug software
and hardware modules. The tool's support documentation is electronically available within the Code
Composer Studio™ Integrated Development Environment (IDE).
The following products support development of TMS320DM816x processor applications:
Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE):
including Editor C/C++ and Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software DSP/BIOS™, which provides the basic run-time target software
needed to support any DaVinci Video Processor application.
Hardware Development Tools: Extended Development System ( XDS™) Emulator
For a complete listing of development-support tools for the DM816x DaVinci™ Video Processor platform,
visit the Texas Instruments website at www.ti.com. For information on pricing and availability, contact the
nearest TI field sales office or authorized distributor.
Device and Development Support-Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
DSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX,
TMP, or TMS (for example, TMS320DM8168CYG). Texas Instruments recommends two of three possible
prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of
product development from engineering prototypes (TMX and TMDX) through fully qualified production
devices and tools (TMS and TMDS).
Device development evolutionary flow:
TMX
Experimental device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
TMP
Prototype device that is not necessarily the final silicon die and may not necessarily meet
final electrical specifications.
TMS
Production version of the silicon die that is fully qualified.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully-qualified development-support product.
TMX and TMP devices and TMDX development-support tools are shipped against the following
disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and TMDS development-support tools have been characterized fully, and the quality
and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard
production devices. Texas Instruments recommends that these devices not be used in any production
system because their expected end-use failure rate still is undefined. Only qualified production devices are
to be used.

TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, CYG), the temperature range (for example, blank is the default commercial
operating junction temperature range), and the device speed range (for example, blank is the default [930MHz ARM, 750-MHz DSP]).
Figure 10-1 provides a legend for reading the complete device name for any TMS320DM816x device. For
a comparison of device features, see Table 3-1.
For device part numbers and further ordering information of TMS320DM816x devices in the CYG package
type, see the TI website (www.ti.com) or contact your TI sales representative.
For additional description of the device nomenclature markings on the die, see the TMS320DM816x

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.
Important Information and Disclaimer:The information provided on this page represents TI's knowledge and belief as of the date that it is provided. TI bases its knowledge and belief on information
provided by third parties, and makes no representation or warranty as to the accuracy of such information. Efforts are underway to better integrate information from third parties. TI has taken and
continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.
TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.
In no event shall TI's liability arising out of such information exceed the total purchase price of the TI part(s) at issue in this document sold by TI to Customer on an annual basis.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
