The FT2232D is an updated version of FTDI's 3rd generation USB UART / FIFO I.C. family.This device features two Multi-Purpose UART / FIFO controllers which can be configured individually in several different modes. As well as a UART interface, FIFO interface and Bit-Bang IO modes of the 2nd generation FT232BM and FT245BM devices, the FT2232D offers a variety of additional new modes of operation, including a Multi-Protocol Synchronous Serial Engine interface which is designed specifically for synchronous serial protocols such as JTAG, I2C, and SPI bus. The FT2232D is fully pin to pin compatible with the previous FT2232C and FT2232L devices. In addition to supporting all of the FT2232C / FT2232L functionallity, the FT2232D has an additional interface mode, CPU FIFO mode, and is specified for -40 to +85 degrees C operation. The FT2232D is available in Pb-free (RoHS compliant) compact 48-Lead LQFP package.
