Product Overview

The FT232HQ-REEL is a single channel USB to multipurpose UART/FIFO IC, operating at USB high-speed 480Mbps rate, this fast single channel bridge chip features either a flexible serial interface or parallel FIFO interface, with data transfer speeds up to 40Mbps. Using a serial EEPROM interface, this device can be configured for a wide variety of asynchronous and synchronous serial standards, such as JTAG, SPI, I²C and UART as well as synchronous and asynchronous parallel FIFO interfaces. In addition, this device features the new synchronous, half-duplex FT1248 bus, which allows an engineer to trade off bandwidth for pin count using 1, 2, 4 or 8 data lines at up to 30Mbps. The I/O structure is 3.3V with built-in tolerance for 5V, allowing the designer maximum flexibility when interfacing with FPGAs. On-board voltage regulation provides 3.3 and 1.8V supplies from a 5V source, as well as a power-on-reset function.
  • Single channel USB to serial/parallel ports with a variety of configurations
  • Entire USB protocol handled on chip, no USB specific firmware programming required
  • USB 2.0 high-speed (480Mbps) and full-speed (12Mbps) compatible
  • Multi-protocol synchronous serial engine (MPSSE) to simplify synchronous serial protocol design
  • UART transfer data rate up to 12Mbaud (RS232 data rate limited by external level shifter)
  • USB to asynchronous 245 FIFO mode for transfer data rate up to 8Mbps
  • USB to synchronous 245 parallel FIFO mode for transfers up to 40Mbps
  • Supports a half duplex FT1248 interface with a configurable width, bi-directional data bus
  • CPU-style FIFO interface mode simplifies CPU interface design
  • Fast serial interface option
  • FTDI's royalty-free virtual com port (VCP) and direct (D2XX) drivers
  • Adjustable receive buffer timeout
  • Option for transmit and receive LED drive signals
  • Bit-bang mode interface option with RD# and WR strobes
  • Highly integrated design includes 5 to 3.3/+1.8V LDO regulator for VCORE, integrated POR function
  • Asynchronous serial UART interface option with full hardware handshaking and modem interface signals
  • Fully assisted hardware or X-On/X-Off software handshaking
  • UART interface supports 7/8-bit data, 1/2 stop bits and odd/even/mark/space/no parity
  • Auto-transmit enable control for RS485 serial applications using TXDEN pin
  • Operation configuration mode and USB description strings configurable in external EEPROM over USB
