XR17C158
5V PCI BUS OCTAL UART
AUGUST 2005
REV. 1.4.3
GENERAL DESCRIPTION
The XR17C1581 (158) is an octal Universal
Asynchronous Receiver and Transmitter (UART). The
device is designed to meet the 32-bit PCI Bus and
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, transmit and receive FIFOs of 64 bytes,
fully programmable transmit and receive FIFO level
triggers, transmit and receive FIFO level counters,
automatic RTS/CTS or DTR/DSR 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.
NOTE: 1 Covered by U.S. Patents #5,649,122 and #5,949,787
