XR17D154
UNIVERSAL (3.3V AND 5V) PCI BUS QUAD UART
AUGUST 2005
REV. 1.2.2
GENERAL DESCRIPTION
The XR17D1541 (D154) is a quad PCI Bus Universal
Asynchronous Receiver and Transmitter (UART) with
same package and pin-out as the Exar XR17C158,
XR17D158 and XR17C154. 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 inputs/outputs and a 16-bit
general purpose timer/counter.
NOTE: 1 Covered by U.S. Patents #5,649,122, #5,949,787
