Features and Overview

  • Hardware implementation of IrDA low-speed, physical-layer transmitter
  • Data bit rate selectable to a maximum transmit rate of 115.2 kbps
  • Optional interrupt on transmit buffer empty

The IrDATX User Module is an 8-bit serial half-duplex transmitter that implements the IrDA low-speed physical layer protocol for infrared communications. Baud rates up to 115.2 kbps can be generated. The data format includes a start bit, 8 bits of data, and a stop bit. Flexible clocking and interrupts are supported. Application Programming Interface (API) firmware routines are provided to initialize, configure, and transmit data. Additional information regarding IrDA is available at http://www.irda.org.
