XR16M698
1.62V TO 3.63V HIGH PERFORMANCE OCTAL UART WITH 32-BYTE FIFO
MAY 2008
REV. 1.0.0
GENERAL DESCRIPTION
The XR16M6981 (698), 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 communication
systems. The global interrupt source register
provides a complete interrupt status indication for all
8 channels to speed up interrupt parsing. Each UART
has its own 16C550 compatible set of configuration
registers, TX and RX FIFOs of 32 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.
NOTE: Covered by US patents #5,649,122 and #5,949,787
