FT232H SINGLE CHANNEL HI-SPEED USB TO MULTIPURPOSE UART/FIFO IC Datasheet Version 2.0 Document No.: FT 000288 Clearance No.: FTDI 199 Future Technology Devices International Ltd FT232H Single Channel Hi- Speed USB to Multipurpose UART/FIFO IC The FT232H is a single channel USB 2.0 Hi-Speed Option for transmit and receive LED drive (480Mb/s) to UART/FIFO IC. It has the capability of signals. being configured in a variety of industry standard Bit-bang Mode interface option with RD and serial or parallel interfaces. The FT232H has the WR strobes following advanced features: Highly integrated design includes 5V to 3.3/+1.8V LDO regulator for VCORE, integrated Single channel USB to serial / parallel ports POR function with a variety of configurations. Asynchronous serial UART interface option with Entire USB protocol handled on the chip. No full hardware handshaking and modem USB specific firmware programming required. interface signals. USB 2.0 Hi-Speed (480Mbits/Second) and Full Fully assisted hardware or X-On / X-Off Speed (12Mbits/Second) compatible. software handshaking. Multi-Protocol Synchronous Serial Engine UART Interface supports 7/8 bit data, 1/2 stop (MPSSE) to simplify synchronous serial protocol 2 bits, and Odd/Even/Mark/Space/No Parity. (USB to JTAG, I C, SPI (MASTER) or bit-bang) Auto transmit enable control for RS485 serial design. applications using the TXDEN pin. UART transfer data rate up to 12Mbaud.
