UM232H Single Channel USB Hi-Speed FT232H Development Module

FTDI, Future Technology Devices International Ltd

The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilizes the FT232H USB Hi-Speed (480Mb/s) single-port bridge chip to handle the USB signaling and protocols.

Product Description

The UM232H is a USB-to-serial/FIFO development module in the FTDI product range which utilizes 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.

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.

The UM232H development module requires USB device drivers, available free from the FTDI website.

There is the Virtual Com Port driver which allows the UM232H to appear as a serial port allowing legacy applications for serial ports to function over USB (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT232H on the UM232H through a DLL.

Supported platforms include: current Microsoft® Windows® operating systems, Linux®, Mac OS® and Microsoft Windows CE® version 4.2 onwards.
