XR17C154
5V PCI BUS QUAD UART
REV. 1.3.0
GENERAL DESCRIPTION
The XR17C154
1
(154) is a quad PCI Bus Universal
Asynchronous Receiver and Transmitter (UART) with
same package and pin-out as the Exar XR17x158 oc-
tal UARTs. The device is designed to meet today鈥檚
32-bit PCI Bus and high bandwidth requirements in
communication systems. The global interrupt source
register provides a complete interrupt status indica-
tion 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 trans-
mit and receive FIFO trigger levels, transmit and re-
ceive FIFO level counters, automatic hardware flow
control with programmable hysteresis, automatic soft-
ware (Xon/Xoff) flow control, IrDA (Infrared Data As-
sociation) encoder/decoder, 8 multi-purpose defin-
able inputs/outputs, and a 16-bit general purpose tim-
er/counter.
