XR17D154

UNIVERSAL (3.3V AND 5V) PCI BUS QUAD UART

AUGUST 2005

REV. 1.2.2

GENERAL DESCRIPTION

FEATURES

• High Performance Quad PCI UART

The XR17D154 (D154) is a quad PCI Bus Universal

Asynchronous Receiver and Transmitter (UART) with

same package and pin-out as the Exar XR17C158,

XR17D158 and XR17C154. 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 all 4 channels to speed up

interrupt parsing. Each UART is independently

controlled and has its own 16C550 compatible 5G

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, IrDA (Infrared Data Association) encoder/

decoder, 8 multi-purpose inputs/outputs and a 16-bit

general purpose timer/counter.

• Universal PCI Bus Buffers - Auto-sense 3.3V or 5V

Operation

• 32-bit PCI Bus 2.3 Target Signalling Compliance

• A Global Interrupt Source Register for all 4 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 Selectable Turn-around Delay

■ Infrared (IrDA 1.0) Data Encoder/Decoder

■ Programmable Data Rate with Prescaler

■ Up to 6.25 Mbps Serial Data Rate at 8X

• Eight Multi-Purpose Inputs/outputs

• General Purpose 16-bit Timer/Counter

• Sleep Mode with Automatic Wake-up

• EEPROM Interface for PCI Configuration

• Same package and pin-out as the XR17D158,

XR17C158 and XR17C154 (20x20x1.4mm 144-

LQFP)

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

APPLICATIONS

• Universal Form Factor PCI Bus Add-in Card

• Remote Access Servers

• Ethernet Network to Serial Ports

• Network Management

• Factory Automation and Process Control

• Point-of-Sale Systems

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