FT4232H QUAD HIGH SPEED USB TO MULTIPURPOSE UART/MPSSE IC  
Datasheet Version 2.09  
Clearance No.: FTDI#78  
Future Technology  
Devices International Ltd  
FT4232H Quad High Speed  
USB to Multipurpose  
UARTMPSSE IC  
/
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).  
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.  
FT4232H has the following advanced  
features:  
The  
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).  
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.  
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.
