FT2232H Dual High Speed USB to Multipurpose UART/FIFO IC Datasheet Version 2.6 Document No.: FT 000061 Clearance No.: FTDI 77 Future Technology Devices International Ltd FT2232H Dual High Speed USB to Multipurpose UART/FIFO IC FT245B-style FIFO interface option with bi- th The FT2232H is FTDIs 5 generation of USB directional data bus and simple 4 wire devices. The FT2232H is a USB 2.0 High Speed handshake interface. (480Mb/s) to UART/FIFO IC. It has the capability of Highly integrated design includes +1.8V LDO being configured in a variety of industry standard regulator for VCORE, integrated POR function serial or parallel interfaces. The FT2232H has the and on chip clock multiplier PLL (12MHz following advanced features: 480MHz). Asynchronous serial UART interface option with Single chip USB to dual serial / parallel ports full hardware handshaking and modem with a variety of configurations. interface signals. Entire USB protocol handled on the chip. No Fully assisted hardware or X-On / X-Off USB specific firmware programming required. software handshaking. USB 2.0 High Speed (480Mbits/Second) and UART Interface supports 7/8 bit data, 1/2 stop Full Speed (12Mbits/Second) compatible. bits, and Odd/Even/Mark/Space/No Parity. Dual Multi-Protocol Synchronous Serial Engine Auto-transmit enable control for RS485 serial (MPSSE) to simplify synchronous serial protocol 2 applications using TXDEN pin. (USB to JTAG, I C, SPI or bit-bang) design. Operational configuration mode and USB Dual independent UART or FIFO or MPSSE Description strings configurable in external ports. EEPROM over the USB interface. Independent Baud rate generators. Configurable I/O drive strength (4, 8, 12 or RS232/RS422/RS485 UART Transfer Data Rate 16mA) and slew rate. up to 12Mbaud. (RS232 Data Rate limited by Low operating and USB suspend current. external level shifter). Supports bus powered, self-powered and high- USB to parallel FIFO transfer data rate up to 8 power bus powered USB configurations. Mbyte/Sec. UHCI/OHCI/EHCI host controller compatible. Single channel synchronous FIFO mode for USB Bulk data transfer mode (512 byte packets transfers upto 40 Mbytes/Sec in High Speed mode). CPU-style FIFO interface mode simplifies CPU +1.8V (chip core) and +3.3V I/O interfacing interface design. (+5V Tolerant). MCU host bus emulation mode configuration Extended -40C to 85C industrial operating option. temperature range. Fast Opto-Isolated serial interface option. Compact 64-LD Lead Free LQFP or QFN FTDIs royalty-free Virtual Com Port (VCP) and package Direct (D2XX) drivers eliminate the Available in compact Pb-free 56 Pin VQFN requirement for USB driver development in packages (RoHS compliant) most cases. Adjustable receive buffer timeout. +3.3V single supply operating voltage range. Option for transmit and receive LED drive ESD protection for FT2232H IOs: signals on each channel. Human Body Model (HBM) 2kV, Enhanced bit-bang Mode interface option with Machine Mode (MM) 200V, RD and WR strobes Charge Device Model (CDM) 500V, Latch-up free.
