XR17D152
UNIVERSAL (3.3V AND 5V) PCI BUS DUAL UART
REV. 1.2.0
GENERAL DESCRIPTION
The XR17D152
1
(D152) 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
complete interrupt status indication for both channels
to speed up interrupt parsing. Each UART is
independently controlled and has its own 16C550
compatible 5G (Fifth Generation) 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, automatic half-duplex control output, wireless
IrDA (Infrared Data Association) infrared encoder/
decoder, 8 multi-purpose inputs/outputs and a 16-bit
general purpose timer/counter.
