Product Overview

The FT4232HQ-R is a 5th generation USB 2.0 High-speed (480Mbps) to UART IC. It has the capability of being configured in a variety of industry standard serial or parallel interfaces. The IC features 4 UARTs. Two of these have an option to independently configure an MPSSE engine, this allows the IC to operate as two UART/bit-bang ports plus two MPSSE engines used to emulate JTAG, SPI, I²C, bit-bang or other synchronous serial modes.
  • Single chip USB to quad serial 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
  • Two multi-protocol synchronous serial engine (MPSSE) on channel A and channel B
  • Independent baud rate generators
  • RS232/RS422/RS485 UART transfer data rate up to 12Mbaud (RS232 Data Rate Limited)
  • FTDI's royalty-free virtual com port (VCP) and direct (D2XX) drivers
  • Optional traffic TX/RX indicators can be added with LEDs and an external 74HC595 shift register
  • Adjustable receive buffer timeout
  • Support for USB suspend and resume conditions via PWREN#, SUSPEND# and RI# pins
  • Highly integrated design
  • FTDI FT232B style, asynchronous serial UART interface option
  • 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
  • Operational configuration mode and USB description strings configurable in external EEPROM over USB
  • Low operating and USB suspend current
  • Configurable I/O drive strength (4, 8, 12 or 16mA) and slew rate
  • Supports bus powered, self powered and high-power bus powered USB configurations
  • UHCI/OHCI/EHCI host controller compatible
