XR16V698
2.25V TO 3.6V HIGH PERFORMANCE OCTAL UART WITH 32-BYTE FIFO
JULY 2008
REV. 1.0.3
GENERAL DESCRIPTION
The XR16V6981 (698), is a 2.25V to 3.6V octal
Universal Asynchronous Receiver and Transmitter
(UART) with 5V tolerant inputs. 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
