XR17L154
3.3V PCI BUS QUAD UART
OCTOBER 2002
REV. 1.0.0
GENERAL DESCRIPTION
The XR17L154
1
(L154) is a quad PCI Bus Universal
Asynchronous Receiver and Transmitter (UART) with
same package and pin-out as the Exar XR17C158
octal UART. 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 complete interrupt status
indication for all 4 channels to speed up interrupt
parsing. Each UART is independently controlled and
has its own 16C550 compatible 5G register set,
transmit and receive 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, IrDA (Infrared Data Association) encoder/
decoder, 8 multi-purpose definable inputs/outputs,
and a 16-bit general purpose timer/counter.
