FT2232D Dual USB to
The FT2232D is a dual USB to serial UART or
FIFO interface with the following advanced
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 I2C, USB to
SPI) design.
CPU-style FIFO interface mode simplifies CPU
interface design.
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
most cases.
Highly integrated design includes 3.3V LDO
regulator for USB I/O, integrated POR function
and on chip clock multiplier PLL (6MHz
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.
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.
Operational configuration mode and USB
Description strings configurable in external
EEPROM over the USB interface.
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 2.0 Full Speed (12Mbits/Second)
Extended -40°C to 85°C industrial operating
temperature range.
Compact 48-LD Lead Free LQFP package
+4.35V to +5.25V single supply operating
voltage range.
Dedicated Windows DLLs available for USB to
JTAG, USB to SPI, and USB to I2C applications.
ESD protection for FT2232D IO‟s:
Human Body Model (HBM) ±2kV,
Machine Mode (MM) ±100V,
Charge Device Model (CDM) ±500V,
Latch-up free..

1.0 Driver Support
The FT2232D requires USB drivers (listed below), available free from, 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.
