FT2232H Dual High Speed
USB to Multipurpose
The FT2232H is FTDI’s 5th generation of USB
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 or MPSSE
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
Single channel synchronous FIFO mode for
transfers upto 40 Mbytes/Sec
CPU-style FIFO interface mode simplifies CPU
MCU host bus emulation mode configuration
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
Adjustable receive buffer timeout.
Option for transmit and receive LED drive
signals on each channel.
Enhanced bit-bang Mode interface option with
RD# and WR# strobes
FT245B-style FIFO interface option with bi-
directional data bus and simple 4 wire
Highly integrated design includes +1.8V LDO
regulator for VCORE, integrated POR function
and on chip clock multiplier PLL (12MHz –
Asynchronous serial UART interface option with
full hardware handshaking and modem
Fully assisted hardware or X-On / X-Off
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.
Configurable I/O drive strength (4, 8, 12 or
16mA) and slew rate.
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
Extended -40°C to 85°C industrial operating
Compact 64-LD Lead Free LQFP or QFN
Available in compact Pb-free 56 Pin VQFN
packages (RoHS compliant)
+3.3V single supply operating voltage range.
ESD protection for FT2232H IO’s:
Human Body Model (HBM) ±2kV,
Machine Mode (MM) ±200V,
Charge Device Model (CDM) ±500V,
