FT2232C Dual USB UART / FIFO I.C.
1.0 Introduction
The FT2232C is the 3rd generation of FTDI’s popular 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 FT2232C
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 and SPI bus.
