UM232H Single Channel USB Hi-Speed FT232H Development Module
Datasheet Version 1.2
Clearance No.: FTDI# 198
1 Introduction
The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilises the
FT232H USB Hi-Speed (480Mb/s) single-port bridge chip to handle the USB signaling and protocols. The
UM232H is ideal for development purposes to quickly prove functionality of adding USB to a target design.
The UM232H is a module designed to plug into a standard 0.6” wide 28 pin DIP socket. The USB connection
to a host system is via a mini-B USB connector. All components used, including the FT232H, are Pb-free
(RoHS compliant).

1.1 FT232H
The FT232H is a single channel USB 2.0 Hi-Speed (480Mb/s) to Serial/FIFO IC. It can be configured in a
variety of serial or parallel interfaces, such as UART, FIFO or FTDI’s MPSSE mode which can configure either
of the following interfaces: JTAG, SPI and I2C. For MPSSE mode, there is also 14 bit-banging lines available
along with the four interface lines. In addition to these, the FT232H supports a CPU-Style FIFO mode and a
fast serial interface mode. It also introduces a half-duplex FT1248 interface that provides a flexible data
communication and high performance interface between the FT232H device and external logic. For further
details on the FT232H and the FT1248 mode, please refer to the FT232H datasheet and application note:
