FT2232H
Dual High Speed
USB to Multipurpose
UART/FIFO IC
The FT2232H is FTDI’s 5
th
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

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, I
2
C, SPI or bit-bang) design.
Dual independent UART or FIFO ports
configurable using MPSSEs.
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 10
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
Direct (D2XX) drivers eliminate the requirement
for USB driver development in most cases.
Adjustable receive buffer timeout.

Tolerant).
Extended -40°C to 85°C industrial operating
temperature range.
Compact 64-LD Lead Free LQFP or LQFN
package
+3.3V single supply operating voltage range.
