5V PCI BUS DUAL UART

REV. 1.2.0

JUNE 2004

FEATURES

GENERAL DESCRIPTION

• High Performance Dual PCI UART

The XR17C152¹(152) 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 com-

plete interrupt status indication for both channels to

speed up interrupt parsing. Each UART is indepen-

dently controlled and has its own 16C550 compatible

5G (Fifth Generation) register set, transmit and re-

ceive 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) in-

frared encoder/decoder, 8 multi-purpose definable in-

puts/outputs, and a 16-bit general purpose timer/

counter.

• PCI Bus 2.2 Target Interface Compliance

• 5V PCI Bus Compliant up to 33MHz Clock

• 32-bit PCI Bus Interface with EEPROM Interface

• A Global Interrupt Source Register for both UARTs

• Data Transfer in Byte, Word and Double-word

• Data Read/Write Burst Operation

• Each UART is independently controlled with:

•16C550 Compatible 5G Register Set

•64-byte Transmit and Receive FIFOs

•Transmit and Receive FIFO Level Counters

•Automatic RTS/CTS or DTR/DSR Flow Control

•Automatic Xon/Xoff Software Flow Control

•Automatic RS485 Half-duplex Control Output with

16 Selectable Turn-around Delay

•Infrared (IrDA 1.0) Data Encoder/Decoder

•Programmable Data Rate with Prescaler

NOTE: 1 Covered by U.S. Patents #5,649,122, #5,949,787

•Up to 6.25 Mbps Serial Data Rate at 5V and 8X

APPLICATIONS

Sampling

• Network Management

• Eight Multi-Purpose Inputs/outputs

• Factory Automation and Process Control

• Ethernet Network to Serial Ports

• Point-of-Sale Systems

• A General Purpose 16-bit Timer/Counter

• Sleep Mode with Automatic Wake-up Indicator

• Same package and pinout as the XR17D152

(14x14x1.0mm TQFP package)

• Remote Access Servers

• Multi serial ports RS-232/RS-422/RS-485 Cards
