FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC
Datasheet Version 2.2
Clearance No.: FTDI#78
3.4.3 FT4232H pins used in an MPSSE
The FT4232H channel A and channel B each have a Multi-Protocol Synchronous Serial Engine (MPSSE).
Each MPSSE can be independently configured to a number of industry standard serial interface protocols
such as JTAG, I2C or SPI, or it can be used to implement a proprietary bus protocol. For example, it is
possible to use one of the FT4232H’s channels (e.g. channel A) to connect to an SRAM configurable FPGA
such as supplied by Altera or Xilinx. The FPGA device would normally be un-configured (i.e. have no
defined function) at power-up. Application software on the PC could use the MPSSE to download
configuration data to the FPGA over USB. This data would define the hardware function on power up. The
other MPSSE channel (e.g. channel B) would be available for another serial interface function while
channel C and channel D can be configured as UART or bit-bang mode. Alternatively each MPSSE can be
used to control a number of GPIO pins. When configured in this mode, the pins used and the descriptions
of the signals are shown in Table 3.7

Table 3.7 Channel A and Channel B MPSSE Configured Pin Descriptions
For a functional description of this mode, please refer to section 4.4.
When either Channel A or Channel B or both channels are used in MPSSE mode, Channel C and Channel
D can be configured as asynchronous serial interface (RS232/422/485) or Bit-Bang mode or a
combination of both.
