The FT2232H is FTDI‟s 5th generation of USB
directional data bus and simple
handshake interface.
Highly integrated design includes +1.8V LDO
regulator for VCORE, integrated POR function
and on chip clock multiplier PLL (12MHz –
480MHz).
Asynchronous serial UART interface option with
full hardware handshaking and modem
interface signals.
Fully assisted hardware or X-On / X-Off
software handshaking.
UART Interface supports 7/8 bit data, 1/2 stop
bits, and Odd/Even/Mark/Space/No Parity.
Auto-transmit enable control for RS485 serial
applications using TXDEN pin.
Operational configuration mode and USB
Description strings configurable in external
EEPROM over the USB interface.

devices. The FT2232H is a USB 2.0 High
Speed (480Mb/s) to UART/FIFO IC. It has the
capability of being configured in a variety of
industry standard serial or parallel interfaces.
The FT2232H has the following advanced
features:
Single chip USB to dual serial / parallel ports
with a variety of configurations.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
USB 2.0 High Speed (480Mbits/Second) and
Full Speed (12Mbits/Second) compatible.
Dual Multi-Protocol Synchronous Serial Engine
(MPSSE) to simplify synchronous serial protocol
(USB to JTAG, I2C, SPI or bit-bang) design.
Dual independent UART or FIFO ports
configurable using MPSSEs.
Configurable I/O drive strength (4, 8, 12 or
16mA) and slew rate.
Independent Baud rate generators.
RS232/RS422/RS485 UART Transfer Data Rate
up to 12Mbaud. (RS232 Data Rate limited by
external level shifter).
USB to parallel FIFO transfer data rate up to 8
Mbyte/Sec.
Single channel synchronous FIFO mode for
transfers > 25 Mbytes/Sec
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
Low operating and USB suspend current.
Supports bus powered, self powered and high-
power bus powered USB configurations.
UHCI/OHCI/EHCI host controller compatible.
USB Bulk data transfer mode (512 byte packets
in High Speed mode).
+1.8V (chip core) and +3.3V I/O interfacing
(+5V Tolerant).
Extended -40°C to 85°C industrial operating
temperature range.
Compact 64-LD Lead Free LQFP or QFN
package
+3.3V single supply operating voltage range.
ESD protection for FT2232H IO‟s:
Human Body Model (HBM) ±2kV,
Direct
(D2XX)
drivers
eliminate
the
requirement for USB driver development in
most cases.
Machine Mode (MM) ±200V,
Adjustable receive buffer timeout.
Option for transmit and receive LED drive
signals on each channel.
Charge Device Model (CDM) ±500V,
Latch-up free.
Enhanced bit-bang Mode interface option with
RD# and WR# strobes
