FT2232D - Dual USB UART/FIFO IC

Two multi-purpose UART/FIFO controllers which can be configured individually in several different modes.

* The FT2232D is a previous generation device. FT2232H is recommended for new designs.

* The FT2232D is a previous generation device. FT2232H is recommended for new designs.

As well as a UART interface, FIFO interface and Bit-Bang IO modes of the 2nd generation FT232B and FT245B devices, the FT2232 offers a variety of additional new modes of operation, including a Multi-Protocol Synchronous Serial Engine (MPSSE) interface which is designed specifically for synchronous serial protocols such as JTAG, I2C and SPI.

Behaving in the same manner as the FT232B or FT245B devices from FTDI, the FT2232 combines 2 FIFO/UART channels into one USB port to create a composite device with amazing versatility. Users can 'pick & mix' UART's or FIFO's and use either the Virtual Com Port (VCP) drivers or the DLL-based D2XX drivers for each channel allowing total flexibilty.

The FT2232 makes JTAG, I2C, SPI and opto-isolated interfaces possible via the MPSSE engine and related development boards.
