FT2232D
Dual USB to
Serial UART/FIFO IC
The FT2232D is a dual USB to serial UART or
FIFO interface with the following advanced
features:
Single chip USB to dual channel serial / parallel
ports with a variety of configurations.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
Transfer Data Rate 300 to 3 Mbaud.
USB to parallel FIFO transfer data rate up to 1
megabyte / second.
Multi-Protocol Synchronous Serial Engine
(MPSSE) to simplify synchronous serial
protocol (USB to JTAG, USB to I
2
C, USB to
SPI) design.
CPU-style FIFO interface mode simplifies CPU
interface design.
MCU host bus emulation mode configuration
option.
Fast Opto-Isolated serial interface option.
FTDI‟s royalty-free Virtual Com Port (VCP) and
Direct
(D2XX)
drivers
eliminate
the
requirement for USB driver development in
most cases.
Highly integrated design includes 3.3V LDO
regulator for USB I/O, integrated POR function
and on chip clock multiplier PLL (6MHz –
48MHz).
Asynchronous serial UART interface option with
full hardware handshaking and modem
interface signals.
Enhanced bit-bang Mode interface option with
RD# and WR# strobes.
Configurable I/O drive strength.

1.0 Driver Support
The FT2232D requires USB drivers (listed below), available free from
http://www.ftdichip.com,
which
are used to make the FT2232D appear as a virtual COM port (VCP). This then allows the user to
communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another
FTDI USB driver, the D2XX driver, can also be used with application software to directly access the
FT2232D though a DLL.
