The FT313H has a fast advance general purpose interface to communicate with most types of
microcontrollers and microprocessors. This microcontroller interface is configured using pins
ALE/ADV_N and CLE to accommodate most types of interfaces. The bus interface supports 8bit and 16-bit, which can be configured using bit DATA_BUS_WIDTH. Three bus interface types
are selected using inputs ALE/ADV_N and CLE during power up, the RD_N /RE_N/OE_N and
CS_N/CE_N pins, or the RESET_N pin. Table 4.1 provides detail of bus configuration for each
mode. Table 4.2 shows pinout information of each bus interface.

Table 4-2 Pin information of the bus interface
4.2 SRAM bus interface mode
The bus interface will be in SRAM 16-bit mode if pins ALE/ADV_N and CLE are HIGH, when:
• The CS_N/CE_N pin goes LOW, and the RD_N /RE_N/OE_N pin goes LOW.
Then, if the DATA_BUS_WIDTH bit is set, the bus interface will be in SRAM 8-bit mode.
In SRAM mode, A[7:0] is the 8-bit address bus and AD[15:0] is the separate 16-bit data bus.
The FT313H pins RD_N /RE_N/OE_N and WR_N/WE_N are the read and write strobes. The
SRAM bus interface supports both 8-bit and 16-bit bus width that can be configured by setting
or clearing bit DATA_BUS_WIDTH. The DMA transfer is also applicable to this interface.

4.3 NOR bus interface mode
The bus interface will be in NOR 16-bit mode, if pin ALE/ADV_N is HIGH and pin CLE is LOW,
when:
• The CS_N/CE_N pin goes LOW, and the RD_N /RE_N/OE_N pin goes LOW.
Then, if the DATA_BUS_WIDTH bit is set, the bus interface will be in NOR 8-bit mode.
The NOR Flash interface access consists of two phases: address and data.
The address is valid when CS_N/CE_N and ADV_N are LOW, and the address is latched at the
rising edge of ADV_N. For a read operation, WE_N must be HIGH. OE_N is the data output
control. When active, the addressed register or the buffer data is driven to the I/O bus. The
read operation is completed when CS_N/CE_N is de-asserted. For a write operation, OE_N
must be HIGH. The WE_N assertion can start when ADV_N is de-asserted. WE_N is the data
input strobe signal. When de-asserted, data will be written to the addressed register or the
buffer. The write operation is completed when CS_N/CE_N is de-asserted.
4.4 General multiplex bus interface mode
The bus interface will be in general multiplex 16-bit mode, if pin ALE/ADV_N is LOW and pin
CLE is HIGH, when:
• The CS_N/CE_N pin goes LOW, and the RD_N /RE_N/OE_N pin goes LOW.
Then, if the DATA_BUS_WIDTH bit is set, the bus interface will be in general multiplex 8-bit
mode. The general multiplex bus interface supports most advance application processors.
The general multiplex interface access consists of two phases: address and data.
The address is valid when ALE/ADV_N goes HIGH, and the address is latched at the falling
edge of ALE/ADV_N. For a read operation, WR_N/WE_N must be HIGH. RD_N /RE_N/OE_N is
the data output control. When active, the addressed register or the buffer data is driven to the
I/O bus. The read operation is completed when CS_N/CE_N is de-asserted. For a write
operation, RD_N /RE_N/OE_N must be HIGH. The WR_N/WE_N assertion can start when
ALE/ADV_N is de-asserted. WR_N/WE_N is the data input strobe signal. When de-asserted,
data will be written to the addressed register or the buffer. The write operation is completed
when CS_N/CE_N is de-asserted. The DMA transfer is also applicable to this interface.
4.5 Interface mode lock
The bus interface can be locked in any of the modes, SRAM, NOR, or general multiplex, using
bit 3 of the HW Mode Control register. To lock the interface in a particular mode:
1. Read bits 7 and 6 of the SW Reset register.
2. Set bit 3 of the HW Mode Control register to logic 1.
3. Read bits 7 and 6 of the SW Reset register to ensure that the interface is locked in the
desired mode.
Note: the default is 16-bit SRAM mode.
4.6 DMA controller
The DMA controller of the FT313H is used to transfer data between the system memory and
local buffers. It shares data bus AD[15:0] and control signals WR_N/WE_N, RD_N
/RE_N/OE_N, and CS_N/CE_N. The logic is dependent on the bus interface mode setting.
DREQ signal is from the FT313H to indicate the start of DMA transfer. DACK signal is used to
differentiate if data transferred is for the DMA or PIO access. When DACK is asserted, it
indicates that it is still in DMA mode. When DACK is de-asserted, it indicates that PIO is to be
accessed. ALE/ADV_N and CLE are ignored in a DMA access cycle. Correct data will be
captured only on the rising edge of WR_N/WE_N and RD_N /RE_N/OE_N.

FT313H USB2.0 HS Host Controller Datasheet Version 1.2
Clearance No.: FTDI# 318
The DMA controller of the FT313H has only one DMA channel. Therefore, only one DMA read or
DMA write may take place at a time. Assign the DMA transfer length in the Data Session
Length register for each DMA transfer. If the transfer length is larger than the burst counter,
the DREQ signal will de-assert at the end of each burst transfer. DREQ will re-assert at the
beginning of the each burst.
When DMA is transferring data from/to local buffer, if it wants to access local buffer content by
PIO mode, can use auxiliary memory access registers AUX_MEMADDR and AUX_DATAPORT to
read/write data from/to local buffer with single cycle.
For a 16-bit DMA transfer, the minimum burst length is 2 bytes. This means that the burst
length is only one DMA cycle. Therefore, DREQ and DACK will assert and de-assert at each
DMA cycle.
The FT313H will be asserted DMA EOT interrupt to indicate that the DMA transfer has either
successfully completed or terminated.
4.7 EHCI host controller
The FT313H is a one-port EHCI-compatible host controller which supports all the USB 2.0
compliant Low-speed, Full-speed, and High-speed devices and split/preamble transactions for
the HS/FS hub.
The EHCI host controller supports two categories of the transfer types, the periodic and
asynchronous transfer types. The periodic transfer type includes the isochronous and interrupt
transfers, while the asynchronous transfer type includes the control and bulk transfers.
The EHCI host controller has schedule interface that provides to the separate schedules for
each category of the transfer type. The periodic schedule is based on a time-oriented frame list
that represents a slide window of time of the host controller work items. All the ISO and INT
transfers are serviced via the periodic schedule. The asynchronous schedule is a simple circular
list of the schedule work items that provides a round robin service opportunity for all the
asynchronous transfers.
The EHCI host controller contains the Isochronous Transfer Descriptor (iTD), Queue Head (qH)
and Queue Element Transfer Descriptor (qTD), and Split Transaction Isochronous Transfer
Descriptor (siTD) data structure interface to support the isochronous/interrupt/control/bulk
transfers and split transaction.
The EHCI host controller internal buffer memory is 24KB. START_ADDR_MEM register is
allocated from 0x0000 to 0x5FFF.
4.8 System clock
4.8.1 Phase Locked Loop (PLL) clock multiplier
The internal PLL supports 12MHz, 19.2MHz, or 24MHz input, which can be crystal or a clock
already existing in system. The frequency selection can be done using the FREQSEL1 and
FREQSEL2 pins. Table 4.3 provides clock frequency selection.

4.10 BCD mode
The FT313H is an EHCI-compatible host controller with BCD block function, which follows the
Battery Charging Specification Revision 1.2(BC1.2) by USB-IF. The block function that
emulates USB host port as either Charging Downstream Port (CDP) or Dedicated Charging Port
(DCP) which provides higher current source than Standard Downstream Port (SDP).
The BCD logic block will decode the mode of operation and choose by following setting:
1. BCD function is default enable by CONFIG register bit[5] setting.
2. BCD mode selection is default controlled by external pins configuration. Set CONFIG
register bit[15] to take over BCD mode setting by software.
3. Same configuration by CONFIG register bit[14:13] to set BCD mode if software takes
over control.

initially applied or in response to a host controller reset. The initial conditions of a port are:


No peripheral connected
Port disable
The software must not attempt to change the state of the port until the power is stable on the port. The
host is required to have power stable to the port within 20 milliseconds of the zero to one transition.
When a peripheral device is attached, the port state transitions to the connected state and system
software will process this as with any status change notification.

state, the port is sensitive to resume detection.
Writing a ‘0’ to this bit is ignored by the host
controller. The host controller will
unconditionally set this bit to a ‘0’ when:
The software sets Force Port Resume bit to a ‘0’
(From a one)
The software sets Port Reset bit to a ‘1’ (From a

Note: Before setting this bit, RUN/STOP bit
should be set to 0.
Force Port Resume
1 = Resume detected/driven on port.
0 = No resume detected/driven on port.
Software sets this bit to a ‘1’ to resume signal.
The host controller sets this bit to a ‘1’ if a J-to-K

Package Parameters
The FT313H is available in three different packages. The FT313HQ is the QFN-64 package, the FT313HL is
the LQFP-64 package and the FT313HP is the TQFP-64 package. The solder reflow profile for all packages
is described in following sections.
8.1 FT313H Package Markings
8.1.1 QFN-64
An example of the markings on the QFN package are shown in Figure 8-1. The FTDI part number is too
