FT4233HP / FT4232HP
(High Speed USB Bridge with
Type-C/PD3.0 Controller)
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
UART/MPSSE solution.
The FT4233HP/FT4232HP has the following advanced
features:
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
EEPROM.

policy through I2C interface.
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.
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
handshaking.
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 I
2
C 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 –
480MHz).
Extended -40°C to 85°C industrial operating
temperature range.
Available in Pb-free QFN-76/QFN-68/LQFP-80
package (RoHS compliant).

1.1 Driver Support
The
FT4233HP/FT4232HP
requires
USB
drivers
(listed
below),
available
free
from
https://www.ftdichip.com,
which are used to make the FT4233HP/FT4232HP 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 FT4233HP/FT4232HP through a DLL.

1.3
USB Compliant
The FT4233HP/FT4232HP is fully compliant with the USB 2.0 specification and the USB PD 3.0
specification.
It has been given the USB-IF Test-ID 4484*.
* For PD port1
The timing of the rise/fall time of the USB signals is not only dependent on the USB signal drivers, but also
on system and is affected by factors such as PCB layout, external components and any transient protection
present on the USB signals. For USB compliance these may require a slight adjustment. Timing can be
changed by adding appropriate passive components to the USB signals.
