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.
UHCI/OHCI/EHCI host controller compatible.
USB Bulk data transfer mode (512 byte packets in Hi-
Speed mode).
+1.2V (chip core) and +3.3V I/O interfacing (+5V
Tolerant).
Extended -40°C to 85°C industrial operating temperature
range.

1.1 Driver Support
The FT233HP/FT232HP requires USB device drivers (listed below), available free from
http://www.ftdichip.com,
to operate. The VCP version of the driver creates a Virtual COM Port allowing
legacy serial port applications to operate over USB e.g. serial emulator application TTY. Another FTDI
USB driver, the D2XX driver, can also be used with application software to directly access the
FT233HP/FT232HP through a DLL.

1.3 USB Compliant
The FT233HP is fully compliant with the USB 2.0 specification and the USB Type-C & PD 3.0 specification.
It has been given the USB-IF Test-ID (TID) 3425*.
* for PD port1
The timing of the rise/fall time of the USB signals is not only dependant on the USB signal drivers, it is
also dependant 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 also be changed by adding appropriate passive components to the USB signals.
