Product Overview

The UM232R module is a USB - Serial UART (TTL) development module for the FT232R IC device. The module supports USB to UART interfacing at 5V / 3V TTL levels. Voltage levels are set via onboard jumpers. I/O headers available to provide access to all UART and CBUS interface pins of the FT232R device. The UM232R can be configured as either USB bus-powered or self-powered modes. Full hardware handshaking is supported. The UM232R can supports communication at up to 3MBaud at TTL/CMOS levels. The UM232R plugs into a standard 24 pin, 0.6in wide, DIP socket.
  • Single chip USB to UART synchronous 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, 1/2 stop bits and odd/even/mar /spac /no parity
  • Fully assisted hardware or X-On / X-Off software handshaking.
  • Data transfer rates from 300 baud to 3 Mega baud
  • FTDI's royalty-free VCP,D2XX drivers eliminates requirement for USB driver developments.
  • Support for bus powered, self powered and high-power bus powered USB configurations
  • Configurable CBUS I/O pins, Transmit and receive LED drive signals
  • Auto transmit buffer control for RS485 applications
  • Integrated 1024bit internal EEPROM for storing USBVID, PID, serial num, product description strings
