5V PCI BUS OCTAL UART

REV. 1.4.3

AUGUST 2005

FEATURES

GENERAL DESCRIPTION

• High Performance Octal UART

The XR17C158 (158) is an octal Universal

• 32-bit PCI Bus Interface with EEPROM Interface

• Interrupt Source Register for all 8 UARTs

• Data Transfer in Byte, Word and Double-word

• Read/Write Burst Operation

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

• Each UART Includes

• 16C550 Compatible Registers

• 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

• RS485 Half-duplex Control with Selectable Delay

• Infrared (IrDA 1.0) Data Encoder/Decoder

• Programmable Data Rate with Prescaler

• Up to 6.25 Mbps Serial Data Rate

Association) encoder/decoder,

definable inputs/outputs, and

purpose timer/counter.

multi-purpose

16-bit general

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

• Eight Multi-Purpose Inputs/outputs

• A General Purpose 16-bit Timer/Counter

• Sleep Mode with Automatic Wake-up

• 5V Operation (PCI Compliance)

APPLICATIONS

• Remote Access Servers

• Ethernet Network to Serial Ports

• Network Management

• Same package and pinout as the XR17C154,

XR17D154 and XR17D158

• Factory Automation and Process Control

• Point-of-Sale Systems

• 144-pin LQFP Package (20x20x1.4mm)

• Multi-port RS-232/RS-422/RS-485 Cards
