Document No.: FT 000061 FT2232H DUAL HIGH SPEED USB TO MULTIPURPOSE UART/FIFO IC Datasheet Version 2.01 Clearance No.: FTDI 77 Future Technology Devices International Ltd FT2232H Dual High Speed USB to Multipurpose UART/FIFO IC Option for transmit and receive LED drive signals th The FT2232H is FTDIs 5 generation on each channel. of USB devices. The FT2232H is a USB Enhanced bit-bang Mode interface option with RD and WR strobes 2.0 High Speed (480Mb/s) to FT245B-style FIFO interface option with bi- UART/FIFO IC. It has the capability of directional data bus and simple 4 wire being configured in a variety of handshake interface. industry standard serial or parallel Highly integrated design includes +1.8V LDO regulator for VCORE, integrated POR function interfaces. The FT2232H has the and on chip clock multiplier PLL (12MHz following advanced features: 480MHz). Single chip USB to dual serial / parallel ports Asynchronous serial UART interface option with with a variety of configurations. full hardware handshaking and modem interface Entire USB protocol handled on the chip. No signals. USB specific firmware programming required. Fully assisted hardware or X-On / X-Off software USB 2.0 High Speed (480Mbits/Second) and Full handshaking. Speed (12Mbits/Second) compatible. UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity. Dual Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol Auto-transmit enable control for RS485 serial 2 (USB to JTAG, I C, SPI or bit-bang) design. applications using TXDEN pin. Dual independent UART or FIFO ports Operational configuration mode and USB configurable using MPSSEs. Description strings configurable in external Independent Baud rate generators.
