FT2232C

CLEARANCE Item! Limited Stock - please call for quantitites.

FT2232C & FT2232L - Dual USB UART/FIFO ICs (not recommended for new designs - recommended replacement is the FT2232D).

The FT2232C is the 3rd generation of FTDI's popular USB UART/FIFO IC family and the FT2232L is a lead free version of it. 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 FT232BM and FT245BM devices, the FT2232C 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.
