1.62V TO 3.63V HIGH PERFORMANCE OCTAL UART WITH 16-BYTE FIFO .. MAY 2008 REV. 1.0.0 GENERAL DESCRIPTION The XR16M5981 (598), is a 1.62V to 3.63V octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for high bandwidth requirement in munication systems. The global interrupt source register provides a plete interrupt status indication for all 8 channels to speed up interrupt parsing. Each UART has its own 16C550 patible set of configuration registers, TX and RX FIFOs of 16 bytes, fully programmable transmit and receive FIFO trigger levels, automatic RTS/CTS or DTR/DSR hardware flow control with programmable hysteresis, automatic software (Xon/Xoff) flow control, RS-485 half-duplex direction control with programmable turn-around delay, Intel or Motorola bus interface and sleep mode with a wake-up indicator.
