XR17C152
5V PCI BUS DUAL UART
JUNE 2004
REV. 1.2.0
GENERAL DESCRIPTION
The XR17C1521 (152) is a monolithic dual PCI Bus
Universal Asynchronous Receiver and Transmitter
(UART) in Exar’s PCI Bus UART family. The device is
designed to meet today’s 32-bit PCI Bus and high
bandwidth requirement in communication systems.
The global interrupt source register provides a com-
plete interrupt status indication for both channels to
speed up interrupt parsing. Each UART is indepen-
dently controlled and has its own 16C550 compatible
5G (Fifth Generation) register set, transmit and re-
ceive FIFOs of 64 bytes, fully programmable transmit
and receive FIFO trigger levels, transmit and receive
FIFO level counters, automatic hardware flow control
with programmable hysteresis, automatic software
(Xon/Xoff) flow control, automatic half-duplex control
output, wireless IrDA (Infrared Data Association) in-
frared encoder/decoder, 8 multi-purpose definable in-
puts/outputs, and a 16-bit general purpose timer/
counter.
