2.25V TO 3.6V HIGH PERFORMANCE OCTAL UART WITH 32-BYTE FIFO

JULY 2008

REV. 1.0.3

FEATURES

GENERAL DESCRIPTION

• 2.25V to 3.6V with 5V Tolerant Inputs

• Single Interrupt output for all 8 UARTs

• A Global Interrupt Source Register for all 8 UARTs

• 5G “Flat” UART Registers for easier programming

• Simultaneous Initialization of all UART channels

• General Purpose 16-bit Timer/counter

• Sleep Mode with Wake-up Indication

• Highly Integrated Device for Space Saving

• Each UART is independently controlled with:

The XR16V698 (698), is a 2.25V to 3.6V octal

Universal Asynchronous Receiver and Transmitter

(UART) with 5V tolerant inputs. The highly integrated

device is designed for high bandwidth requirement in

communication systems. The global interrupt source

complete interrupt status

indication for all 8 channels to speed up interrupt

parsing. Each UART has its own 16C550 compatible

set of configuration registers, TX and RX FIFOs of 32

bytes, fully programmable transmit and receive FIFO

trigger levels, automatic RTS/CTS or DTR/DSR

hardware flow control with programmable hysteresis,

automatic software (Xon/Xoff) flow control, RS-485

half-duplex direction control with programmable turn-

around delay, Intel or Motorola bus interface and

sleep mode with a wake-up indicator.

■ 16C550 Compatible 5G Register Set

■ 32-byte Transmit and Receive FIFOs

■ Fractional Baud Rate Generator

NOTE: Covered by US patents #5,649,122 and #5,949,787

■ Programmable TX and RX FIFO Trigger Level

■ Automatic RTS/CTS or DTR/DSR Flow Control

■ Automatic Xon/Xoff Software Flow Control

APPLICATIONS

• Remote Access Servers

■ RS-485 Half-Duplex Direction Control Output

• Ethernet Network to Serial Ports

• Network Management

with Selectable Turn-around Delay

■ Infrared (IrDA 1.0) Data Encoder/Decoder

■ Programmable Data Rate with Prescaler

• Factory Automation and Process Control

• Point-of-Sale Systems

• Up to 15 Mbps Serial Data Rate

• Pin compatible to XR16V798. Same 100-pin QFP

Package (14x20x3 mm)

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