Eight Channel BUS PCI UART 32 Bit FIFO Interface Integrated Circuit 144LQFP XR17D158IV-F

High-performance Eight-channel PCI BUS UART 32-bit FIFO Interface Integrated Circuit 144LQFP XR17D158IV-F

GENERAL DESCRIPTION
The XR17D1581 (D158) is an octal PCI Bus
Universal Asynchronous Receiver and Transmitter
(UART) with support for PCI Bus universal VIO
buffers in the same package and pin-out as the
XR17C158, XR17C154 and XR17D154. The device
is designed to meet the 32-bit PCI Bus and high
bandwidth requirement in communication systems. A
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 trigger levels,
transmit and receive FIFO level counters, automatic
RTS/CTS or DTR/DSR hardware flow control with
programmable hysteresis levels, 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 and #5,949,787
