FT2232H - High Speed Dual USB to multi-purpose UART/FIFO IC

The FT2232H is a dual channel device allowing one USB port to connect to two separate interfaces without a USB hub chip. Each channel may be independently configured to support UART, FIFO (synchronous and asynchronous) or, by using the Multi Purpose Synchronous Serial Engine (MPSSE), USB to I2C, SPI, JTAG or other clocked serial interfaces. Also available are MCU Emulation and bitbang modes.

Building on the innovative features of the older FT2232 device, the FT2232H has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.

As with previous generations of FTDI ICs, comprehensive and free driver support is offered for most industry standard operating systems such as Windows, Linux and MAC OSX. This allows developers to focus on their end application rather than spending additional time developing drivers.

The FT2232H is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.

The FT2232H Mini Module is a USB to dual channel serial/MPSSE/FIFO interface converter module based on the FT2232H USB Hi-Speed IC. The FT2232H handles all the USB signalling and protocol handling. The module provides access to device I/O interfaces via 2 double row 0.1" pitch male connectors.  The module is ideal for development purposes to quickly prove functionality of adding USB to a target design.

Versatile Range of Evaluation Kits

The extensive range of FTDI evaluation modules and kits represent the quickest way to get learn about USB, with many of the kits allowing you to get running in less than 30 minutes.

Volume pricing is available which is flexible enough to mean you could embed a module within your design for minimal time-to-market turnaround.
