FT4232H Quad High Speed
USB to Multipurpose
UART/MPSSE IC
The FT4232H is FTDI’s 5th generation of USB devices.
The FT4232H is a USB 2.0 High Speed (480Mb/s) to
UART/MPSSE ICs. The device features 4 UARTs. Two
of these have an option to independently configure
an MPSSE engine. This allows the FT4232H to
operate as two UART/Bit-Bang ports plus two MPSSE
engines used to emulate JTAG, SPI, I2C, Bit-bang or
other synchronous serial modes. The FT4232H has
the following advanced features:
Single chip USB to quad serial 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.
Two Multi-Protocol Synchronous Serial Engine
(MPSSE) on channel A and channel B, to simplify
synchronous serial protocol (USB to JTAG, I2C,
SPI or bit-bang) design.
Independent Baud rate generators.
RS232/RS422/RS485 UART Transfer Data Rate
up to 12Mbaud. (RS232 Data Rate limited by
external level shifter).
FTDI’s royalty-free Virtual Com Port (VCP) and
Direct (D2XX) drivers eliminate the requirement
for USB driver development in most cases.
Optional traffic TX/RX indicators can be added
with LEDs and an external 74HC595 shift
register.
Adjustable receive buffer timeout.
Support for USB suspend and resume conditions
via PWREN#, SUSPEND# and RI# pins.
Highly integrated design includes +1.8V LDO
regulator for VCORE, integrated POR function
and on chip clock multiplier PLL (12MHz
480MHz).
FTDI FT232B style, 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.
Low operating and USB suspend current.
Configurable I/O drive strength (4, 8, 12 or
16mA) and slew rate.
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).
Dedicated Windows DLLs available for USB to
JTAG, USB to SPI, and USB to I2C applications.
+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
Available in compact Pb-free 56 Pin VQFN
packages (RoHS compliant)
+3.3V single supply operating voltage range.
ESD protection for FT4232H IO’s:
Human Body Model (HBM) ±2kV,
Machine Mode (MM) ±200V,
Charge Device Model (CDM) ±500V,
Latch-up free.

1.1 Driver Support
The FT4232H requires USB drivers (listed below), available free from http://www.ftdichip.com, which are
used to make the FT4232H appear as a virtual COM port (VCP). This 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 FT4232H through a DLL.
