Future Technology
Devices International Ltd
( High Speed USB Bridge with
Type-C/PD Controller )
The FT4233H is a Hi-Speed USB device with a Type-
C/PD controller that fully supports the latest USB
Type-C and Power Delivery (PD) standards enabling
support for power negotiation with the ability to sink
or source current to a USB host device. The USB
bridge function delivers 4 independent channels
compatible with the FT4232H Quad Hi-speed USB
to multipurpose UART/MPSSE solution.
The FT4233H has the following advanced features:
Support PD specification Rev 3.0.
Port1 mode configuration for Sink or Dual-role,
supporting Fast Role Swap
Port2 works as Sink, supporting charge through
to port1
Support 5V, 9V, 15V and 20V PDOs as sink or
Type-C/PD Physical Layer Protocol
PD policy engine using 32-bit RISC controller
with 8kB data RAM and 48kB code ROM
Support PD capability descriptors and requests
Options to use external MCU controlling PD
policy through I2C interface
USB to quad serial ports with a variety of
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
Adjustable receive buffer timeout.
Support for USB suspend and resume conditions
via PWREN#, SUSPEND# and RI# pins.
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
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.
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.
+3.3V single supply operating voltage range.
+3.3V I/O interfacing.
Highly integrated design includes +1.2V LDO
regulator for VCORE, integrated POR function
and on chip clock multiplier PLL (12MHz
Extended -40°C to 85°C industrial operating
temperature range.

1.1 Driver Support
The FT4233H requires USB drivers (listed below), available free from, which are
used to make the FT4233H 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 FT4233H through a DLL.
