The FT2232D is lead free and pin compatible with the original FT2232C and FT2232L devices. All the original device features are supported with some additional features available including a CPU-style FIFO mode and an extended operating temperature range.

This device features two multi-purpose UART/FIFO controllers which can be configured individually in several different modes. As well as a UART interface, a FIFO interface and the Bit-Bang IO mode of the 2nd generation FT232B and FT245B devices, the FT2232D 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 I2C, JTAG and SPI bus.
