FT232H
Single Channel Hi-
Speed USB to Multipurpose
UART/FIFO IC
The FT232H is a single channel USB 2.0 Hi-
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 FT232H has the following advanced
features:
Single channel USB to serial / parallel ports
with a variety of configurations.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
USB 2.0 Hi-Speed (480Mbits/Second) and Full
Speed (12Mbits/Second) compatible.
Multi-Protocol
Synchronous
Serial
Engine
(MPSSE) to simplify synchronous serial protocol
(USB to JTAG, I
2
C, SPI (MASTER) or bit-bang)
design.
UART transfer data rate up to 12Mbaud.
(RS232 Data Rate limited by external level
shifter).
USB to asynchronous 245 FIFO mode for
transfer data rate up to 8 Mbyte/Sec.
USB to synchronous 245 parallel FIFO mode for
transfers upto 40 Mbytes/Sec
Supports a proprietary half duplex FT1248
interface with a configurable width, bi-
directional data bus (1, 2, 4 or 8 bits wide).
CPU-style FIFO interface mode simplifies CPU
interface design.
Fast 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.
Option for transmit and receive LED drive
signals.
Bit-bang Mode interface option with RD# and
WR# strobes
Highly integrated design includes 5V to
3.3/+1.8V LDO regulator for VCORE, integrated
POR function
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 the TXDEN pin.
Operational mode configuration and USB
Description strings configurable in external
EEPROM over the USB interface.
Configurable I/O drives strength (4, 8, 12 or
16mA) and slew rate.
Low operating and USB suspend current.
Supports self powered, bus powered and high-
power bus powered USB configurations.
UHCI/OHCI/EHCI host controller compatible.
USB Bulk data transfer mode (512 byte packets
in Hi-Speed mode).
+1.8V (chip core) and +3.3V I/O interfacing
(+5V Tolerant).
Extended -40°C to 85°C industrial operating
temperature range.
Compact 48-pin Lead Free LQFP or QFN
package
Configurable ACBUS I/O pins.
