FT4233HP / FT4232HP
(High Speed USB Bridge with
The FT4233HP/FT4232HP is a Hi-Speed USB device
with a Type-C/PD3.0 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 existing
FT4232H – Quad Hi-speed USB to multipurpose
The FT4233HP/FT4232HP has the following advanced
Supports the PD specification Rev 3.0.
Port 1 mode configuration for Sink or Dual-role.
Port 2 works as Sink, supporting charge through
to Port 1(FT4233HPQ and FT4233HPL only).
Supports 5V3A, 9V3A, 12V3A, 15V3A and 20V3A
PDOs as sink or source.
Type-C/PD Physical Layer Protocol.
PD policy engine using 32-bit RISC controller
with 8kB data RAM and 48kB code ROM.
PD mode configuration through external
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 FT232R/FT-X 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.
Enable control for RS485 serial applications using
TXDEN pin through external EEPROM.
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.
USB Bulk data transfer mode (512 byte packets
in High Speed mode).
Dedicated Windows/Linux DLLs available for 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
