General Description
The Cyclone® III development board provides a hardware platform for developing
and prototyping low-power, high-volume, and feature-rich designs as well as to
demonstrate the Cyclone III device’s on-chip memory, embedded multipliers, and the
Nios® II embedded processor.
With up to 4 Mbits of embedded memory and 288 embedded 18-bit × 18-bit
multipliers, the Cyclone III device supplies internal memory while also providing
external support for high-speed, low-latency memory access via dual-channel DDR
SDRAM and low-power SRAM.
Built on TSMC’s 65-nm low-power process technology, Cyclone III devices are
designed to provide low static and dynamic power consumption. Additionally, with
the support of the Quartus® II software’s PowerPlay technology, designs are
automatically optimized for power consumption. Therefore, the Cyclone III
development board provides a power-optimized, integrated solution for
memory-intensive, high-volume applications.
Accordingly, the Cyclone III development board is especially suitable for wireless,
video and image processing, and other high-bandwidth, parallel processing
applications. Through the use of Altera®-provided video and image intellectual
property (or other MegaCore® functions) and board expansion connectors, you can
enable the inter-operability of the Cyclone III device, allowing application-specific
customization of the development board.

MAX II CPLD
The board utilizes an Altera MAX II CPLD for the following purposes:
■
Power-up configuration of the FPGA from flash memory
■
Embedded USB-Blaster core for USB-based configuration of the FPGA
■
Power consumption monitoring and display
There are two USB MAC/PHY devices— FTDI and Cypress USB PHY devices— on
the board. They are muxed through the MAX II CPLD. Only one can operate at any
time. The FTDI device is the default device and it supports the embedded blaster
functionality. The Cypress USB PHY is held in reset and is reserved for future use.
Each device has a shared path between the USB device and the MAX II CPLD. The
individual paths then drive to the FPGA separately. Figure 2–3 illustrates the MAX II
device’s block diagram.

Configuration
This section discusses FPGA, flash memory, and MAX II device programming
methods supported by the Cyclone III development board.
FPGA Programming Over USB
The FPGA can be configured at any time the board is powered on by using the
USB 2.0 interface and the Quartus II Programmer in JTAG mode.
The JTAG chain is mastered by the embedded USB Blaster function found in the
MAX II device. Only a USB cable is needed to program the Cyclone III FPGA. Any
device can be bypassed by using the appropriate switch on the JTAG control DIP
switch.
1
Board reference SW1 position 5 (SW1.5), labeled MAX0, must be in the closed position
(on) for this feature to properly work. If the SW1 switch is in the closed position, the
parallel flash loader (PFL) megafunction in the MAX II CPLD may try to overwrite
the FPGA image just downloaded over the USB immediately after completion.
For more information about:
■
Advanced JTAG settings, refer to Table 2–7.
■
The JTAG control switch, refer to “JTAG Control DIP Switch” on page 2–19.

The JTAG header can be used with an external USB-Blaster cable, or equivalent, to
program either the MAX II CPLD or configure the Cyclone III FPGA. Most users of
the Cyclone III development board do not use the JTAG header at all and instead use
a USB cable along with the embedded USB-Blaster. Using an external USB-Blaster
with the JTAG header requires disabling the embedded USB-Blaster function. See
Table 2–7.

(3) Requires external USB-Blaster or equivalent plugged into board reference J14 (PCB bottom).
(4) The JTAG chains for both HSMC ports A and B can only be accessed from the embedded USB-Blaster. They cannot be accessed from the
external USB-Blaster header.
FPGA Programming from Flash Memory
On either power-up or by pressing the RESET_CONFIG or FACTORY_CONFIG push
button, the MAX II CPLD device’s PFL megafunction configures the Cyclone III
FPGA from flash memory.
The PFL megafunction reads 16-bit data from the flash memory and converts it to
passive serial format. The data is written to the Cyclone III device’s dedicated DCLK
and D0 configuration pins at 12 MHz.
FPGA configuration from flash memory can be sourced from one of eight images. The
image is selected by the PGM_CONFIG_SELECT rotary switch, board reference SW5.
The rotary switch has 16 positions, but only the first eight are used. The positions
correspond to an offset in flash memory that the PFL is directed to for FPGA
configuration data.
1
Board reference SW1 position 5 (SW1.5), labeled MAX0, must be in the
open position (1) for this feature to be enabled. If the SW1 switch is in the closed (0)
position, the PFL megafunction in the MAX II CPLD is disabled.

Flash Programming over USB Interface
The flash memory can be programmed at any time the board is powered up by using
the USB 2.0 interface and the Quartus II Programmer ’s JTAG mode.
The development kit implements the Altera PFL megafunction for flash
programming. The PFL is a block of logic that is programmed into an Altera
programmable logic device (FPGA or CPLD). The PFL functions as a utility for
writing to a compatible flash device. The development kit ships with a pre-built PFL
design called cycloneIII_3c120_dev_pfl. The PFL design is programmed onto the
FPGA whenever the flash is to be written using the Quartus II software.

System Reset and Configuration Switches
Board reference S6 is the system reset push button switch, RESET_CONFIGn, which is
an input to the MAX II device. It forces a reconfiguration of the FPGA from flash
memory. The location in flash memory is based on the input from the board settings
rotary switch position for the signals PGM [2:0]. The MAX II device uses the
RESET_CONFIGn pin as its reset along with the CPU_RESETn push button.
Board reference S5 is the CPU reset push button switch, CPU_RESET, which is an
input to both the Cyclone III FPGA and the MAX II CPLD. The CPU_RESET push
button is intended to be the master reset signal for the FPGA design loaded in the
Cyclone III device, and connects to the special function pin called DEV_CLR on the
FPGA but is also a regular I/O pin. The MAX II device uses this as its reset along with
the RESET_CONFIG and FACTORY_CONFIG push buttons.
Board reference S7 is the factory push button switch (FACTORY_CONFIG), which is an
input to the MAX II device. The FACTORY_CONFIG pin forces a reconfiguration of the
FPGA with the factory default FPGA design, which is located at the base of flash
memory. See Table 2–14.

Clocking Circuitry
This section describes Cyclone III FPGA clocking inputs and outputs. A diagram is
provided for each section.
Cyclone III FPGA Clock Inputs
Figure 2–5 outlines the clocking inputs to the Cyclone III FPGA.
1
Some signals are connected to 1.8-V banks and some are connected to 2.5-V banks.
Refer to the Cyclone III Device Handbook for information about allowable levels for
driving these inputs from external sources.
The clock 1 and clock 2 signals from the HSMC interface can be used as LVDS pairs or
as eight separate clock signals. These signals include HSMA_CLK_IN_P2/N2,
HSMA_CLK_IN_P1/N1, HSMB_CLK_IN_P2/N2, and HSMB_CLK_IN_P1/N1. These
signals may also be used for bidirectional data. If used in LVDS mode, install
applicable termination resistors between P/N pairs. A voltage translator, National
Semiconductor part number FXLP34, is located in between the HSMC interfaces and
the Cyclone III FPGA to reduce LVTTL to 1.8-V CMOS input levels for clock 0 signals
HSMA_CLK_IN0 and HSMB_CLK_IN0.

General User Interfaces
To allow you to fully leverage the I/O capabilities of the Cyclone III device for
debugging, control, and monitoring purposes, the following general user interfaces
are available on the board:
■
Push buttons
■
DIP switches
■
LEDs
■
7-segment displays
■
LCD displays
User-Defined Push Button Switches
The development board includes four general user, one user reset, one system reset,
and one factory push button switch.
f
For information on the system reset and factory push button switches, refer to
“System Reset and Configuration Switches” on page 2–20.
Board references S1 through S4 are push button switches allowing general user I/O
interfaces to the Cyclone III device. There is no board-specific function for these four
push buttons.
Board reference S5 is the user reset push button switch, CPU_RESETn, which is an
input to the Cyclone III device and MAX II CPLD. It is intended to be the master reset
signal for the FPGA design loaded into the Cyclone III device. This connects to the
special function pin called the DEV_CLR on the FPGA, but it also is a regular I/O pin.
The MAX II device uses the DEV_CLR pin as its reset along with the RESET_CONFIGn
push button.
Table 2–23 lists the schematic signal name and corresponding Cyclone III pin number.

USB 2.0 MAC/PHY
The board incorporates the FTDI USB 2.0 PHY chip. The FT245BL (LQFP package)
provides an easy cost-effective method of transferring data to/from a peripheral and
a host PC at up to 8 million bits (1 Megabyte) per second (Mbps). The simple,
FIFO-like design makes interfacing easier.
The device interfaces to J3, a Type B USB connector similar to those used by common
peripherals such as digital cameras and printers. The maximum speed of the interface
is 12 Mbps. Typical application speeds are around 1.5 Mbps; however, actual system
speed may vary.
The primary usage for the USB device is to provide JTAG programming of on-board
devices such as the FPGA and flash memory. The interface is also the default means
through which the FPGA connects to host PC applications such as SignalTap® II,
DSP Builder, and the Nios II JTAG universal asynchronous receiver/transmitter
(UART).

10/100/1000 Ethernet
The 10/100/1000 Ethernet PHY port is provided using a dedicated 10/100/1000
base-T, auto-negotiating Ethernet PHY with reduced Gigabit media independent
interface (RGMII) to the FPGA. The target device is the Marvell 88E1111, which uses
2.5-V and 1.2-V power rails. The Marvell 88E1111 requires a 25-MHz reference clock
driven from a dedicated oscillator.
The Marvell device is provided for copper RS-45 Ethernet connectivity and comes in
the BCC96 leadless chip carrier package. The device interfaces to a HALO
HFJ11-1G02E model RJ-45.
The PHY device provides 32 internal management registers that can be accessed using
the Management Interface (MDIO). The MDIO address of the PHY device is
configured to the value 18 (0x12).
Figure 2–12 shows the interface between the FPGA and the PHY device.

High-Speed Mezzanine Connector
The board contains two HSMC interfaces called Port A and Port B. These HSMC
interfaces support both single-ended and differential signaling. The connector part
number is Samtec ASP-122953-01. The HSM connector interface also allows for JTAG,
SMBus, clock outputs and inputs, as well as power for compatible HSMC daughter
cards.
The HSMC is an Altera-developed specification, which allows users to expand the
functionality of the development board through the addition of HSMC daughter
cards.
f
For more information about the HSMC specification such as signaling standards,
signal integrity, compatible connectors, and mechanical information, visit
www.altera.com.
The HSM connector has 172 total pins, including 120 signal pins, 39 power pins, and
13 ground pins. The ground pins are located between the two rows of signal and
power pins, acting as both a shield and a reference. The HSM connector is based on
the 0.5 mm-pitch QSH/QTH family of high-speed, board-to-board connectors from
Samtec. There are three banks in this connector. Bank 1 has every third pin removed as
is done in the QSH-DP/QTH-DP series. Bank 2 and Bank 3 have all of the pins
populated as done in the QSH/QTH series.
The Cyclone III development board does not use Bank 1 transceiver signals intended
for clock-data-recover (CDR) applications such as PCI Express and Rapid I/O©. These
32 pins are left floating. Banks 2 and 3 are fully supported and can be used in two
different configurations. See Figure 2–13.

The HSMC interface has programmable bi-directional I/O pins that can be used as
2.5-V LVCMOS, which is 3.3-V LVTTL-compatible. These pins can also be used as
various differential I/O standards including, but not limited to LVDS, mini-LVDS,
and RSDS with up to 17-channels full-duplex. Resistor locations are provided for
board-level differential termination on designated receiver pairs, but are not installed
as CMOS utilization of these pins is the default usage model.

As noted in the HSMC specification, LVDS and single-ended I/O standards are only
guaranteed to function when mixed according to either the generic single-ended
pin-out or the generic differential pin-out.

On-Board Memory
This section describes the on-board memory interface support, provides signal name,
type, and signal connectivity relative to the Cyclone III device.
The board has the following on-board memory:
■
DDR2 SDRAM
■
SRAM
DDR2 SDRAM
The board has 256 MB of dual-channel DDR2 SDRAM memory with a 72-bit data
width. These devices use the 1.8-V SSTL signaling standard.
The data bus can be configured as two separate buses of 32 bits each, or a single 32-bit
and a single 40-bit bus. One address/control bus is referred to as TOP and the other is
referred to as BOT (bottom), as they connect to the respective Cyclone III device
edges. The interface comprises four ×16 devices for the 64-bit datapath, and a single
×8 device for the ECC bits for a total of 5 devices (3 to TOP, 2 to BOT). The Micron part
numbers are MT47H32M16CC-3 for the ×16 devices and MT47H32M8BP-3 for the ×8
device.

The two address buses are large enough to support any size JEDEC-compliant DDR2
device, as they have all 16 address pins and all three bank pins connected. The Micron
components shipped on the board all have 13 row addresses, 2 bank addresses, and
10 column addresses.
1
Unused control pins should be left tri-stated to reduce power consumption.
There are three clock pairs driven from the FPGA to the memories. The first two pairs
clock two memory devices each. The last clock drives the 5th memory device as well
as an additional capacitive load to make all clocks have similar loading.
The maximum frequency is 167 MHz (333 Mbps per pin). The theoretical bandwidth
of the entire DDR2 interface is 2667 Mbps plus ECC, or 3,000 Mbps raw throughput.
f
For more information, visit Micron at www.micron.com.
The data interface to the FPGA fabric runs at either one-half or one-quarter the
physical layer data rate when using the Altera DDR2 MegaCore function, which
equates to a doubling or quadrupling of the physical data bus width (144 bits or
288 bits, respectively). For example, a 72-bit interface with a 200-MHz external clock
speed can have a 200 MHz 144-bit internal bus or a 100 MHz 288-bit interface.
To allow for the use of memory device ODT functionality, the ODT signal is
connected. Because a board-level Class I termination is also available, use of this
feature is optional. Termination resistors are approximately 50Ω to match the trace
impedance of the signals on the board. Clocks are terminated using a single 100Ω
resistor across each P/N pair. Altera recommends using the 50Ω OCT on the FPGA
for data, and the 10 mA setting for the address and control pins. The DDR2 devices
should use the reduced drive strength setting available as a register option.
Table 2–51 lists the DDR2 interface signal name, description, and I/O standard. Signal
name and direction are relative to the Cyclone III FPGA.

On-Board Memory
SRAM
The board features 8 MB of SRAM memory with a 32-bit data bus. The devices use
1.8-V CMOS signaling and are optimized for low cost and power.
The 32-bit interface comprises two ×16 devices. The Samsung part features a
maximum frequency of 104 MHz (104 Mbps). The theoretical bandwidth of the entire
interface is 416 Mbps.
The SRAM devices are part of a shared bus with connectivity to the MAX II CPLD as
well as the flash memory, which is called the FSM bus. All three devices use 1.8-V
CMOS signaling. Altera recommends using the 50-Ω OCT setting on the FPGA and
the one-half drive setting on the SRAM.
Table 2–53 lists the SRAM interface signal name, description, and I/O standard.
Signal name and type are relative to the Cyclone III device, i.e., I/O setting and
direction.

Flash Memory
The board features 64 MB of flash memory with a 16-bit data bus. The device uses
1.8-V CMOS signaling and is used for storing configuration files for the FPGA as well
as any other files such as Nios software binaries, libraries, images, and sounds.
The interface uses a single Spansion device. The part number is S29GL512N11FFIV1.
The device features CFI flash command support, byte- and word-mode operation,
and 110 ns access times for a theoretical read bandwidth of 145 Mbps.
The flash device is part of a shared bus with connectivity to the MAX II CPLD as well
as the SRAM memory, which is called the FSM bus. All three devices use 1.8-V CMOS
signaling. Altera recommends using the 50-Ω OCT setting on the FPGA. The flash
does not have a drive strength setting.
Table 2–56 shows the required signals for flash memory. Signal direction is relative to
the FPGA.

Power Supply
The board’s power is provided through an IBM laptop style DC power input. The
input voltage must be in the range of 14 V to 20 V. The DC voltage is then stepped
down to the various power rails used by the components on the board and installed
into the HSM connectors.
Figure 2–17 shows the power distribution system, which uses current power rails as
described in “POWER SELECT Rotary Switch” on page 2–21. Regulator inefficiencies
and sharing are reflected in the currents shown.

Power Measurement
Eight power supply rails have on-board voltage and current sense capabilities. These
measurements are made using an 8-channel differential A/D converter from Linear
Technology, with a serial data bus connected to the MAX II CPLD.
The MAX II CPLD contains a logic design that continually monitors the power rails
and displays the current in mW on the dedicated four-digit 7-segment display. Rotary
switch SW4 is used to select the power rail being displayed. The sense resistor is large
enough that it can be easily probed by a user to confirm the display results. The
results are also accessible from the FPGA through register access across the FSM bus.
Figure 2–18 illustrates the circuit.
