FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC
Datasheet Version 2.2
Clearance No.: FTDI#78
Future Technology
Devices International Ltd
FT4232H Quad High Speed
USB to Multipurpose
UART/MPSSE IC
The FT4232H is FTDI’s 5
th
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, I
2
C, 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, I
2
C, 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 I
2
C 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
+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.
