The USB232R is the latest RoHS compliant, low-cost integrated module for transferring data to / from a peripheral to a host PC.

The module is based on the FT232R USB to serial UART IC from FTDI.

  • Single module High-Speed USB Serial UART solution that is based on the
  • FTDI FT232R USB IC
  • Integrated Type-B USB Connector
  • RoHS Compliant
  • No external passive components required
  • Module can be configured for both External and Bus powered operation.
  • On board power switching circuit for high bus powered applications
  • 24-pin Dual In-Line Package (Ideal for prototyping)

FT232R Features

  • Single chip USB to asynchronous serial data transfer interface.
  • Entire USB protocol handled on the chip - No USB-specific firmware programming required.
  • UART interface support for 7 or 8 data bits, 1 or 2 stop bits and odd / even / mark / space / no parity.
  • Fully assisted hardware or X-On / X-Off software handshaking.
  • Data transfer rates from 300 baud to 3 Megabaud (RS422 / RS485 and at TTL levels) and 300 baud to 1 Megabaud (RS232).
  • 256 byte receive buffer and 128 byte transmit buffer utilising buffer smoothing technology to allow for high data throughput.
  • FTDI's royalty-free VCP and D2XX drivers eliminate the requirement for USB driver development in most cases.
  • In-built support for event characters and line break condition.
  • New USB FTDI Chip-ID™ feature.
  • New configurable CBUS I/O pins.
  • Auto transmit buffer control for RS485 applications.
  • Transmit and receive LED drive signals.
  • New 48MHz, 24MHz, 12MHz, and 6MHz clock output signal Options for driving external MCU or FPGA.
  • FIFO receive and transmit buffers for high data throughput.
  • Adjustable receive buffer timeout.
  • Synchronous and asynchronous bit bang mode interface options with RD# and WR# strobes.
  • New CBUS bit bang mode option.
  • Integrated 1024 Bit internal EEPROM for storing USB VID, PID, serial number and product description strings, and CBUS I/O configuration.
  • Device supplied preprogrammed with unique USB serial number.
  • Support for USB suspend and resume.
  • Support for bus powered, self powered, and high-power bus powered USB configurations.
  • Integrated 3.3V level converter for USB I/O .
  • Integrated level converter on UART and CBUS for interfacing to 5V - 1.8V Logic.
  • True 5V / 3.3V / 2.8V / 1.8V CMOS drive output and TTL input.
  • High I/O pin output drive option.
  • Integrated USB resistors.
  • Integrated power-on-reset circuit.
  • Fully integrated clock - no external crystal, oscillator, or resonator required.
  • Fully integrated AVCC supply filtering - No separate AVCC pin and no external R-C filter required.
  • UART signal inversion option. USB bulk transfer mode.
  • 3.3V to 5.25V Single Supply Operation.
  • Low operating and USB suspend current.
  • Low USB bandwidth consumption.
  • UHCI / OHCI / EHCI host controller compatible
