XR16L788

HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART

JULY 2008

REV. 1.2.3

FEATURES

GENERAL DESCRIPTION

• 2.97V to 5.5V with 5V Tolerant Inputs Operation

• Single Interrupt Output for all 8 UARTs

• Global Interrupt Source for all 8 UARTs

• 5G “Flat” UART Registers for Configurations

• Simultaneous UART Channels Initialization

The XR16L7881 (788), is a 2.97V to 5.5V with 5V

tolerant inputs octal Universal Asynchronous

Receiver and Transmitter (UART). The highly

integrated device is designed for 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, TX and RX

FIFOs of 64 bytes, fully programmable transmit and

receive FIFO trigger levels, TX and RX FIFO level

counters, automatic RTS/CTS or DTR/DSR hardware

flow control with programmable hysteresis, autoamtic

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.

• Auto RS485 Half-duplex Control with Program-

mable Turn-around Delay

• A General Purpose 16-bit Timer/Counter

• Sleep Mode with Wake-up Indication

• Highly Integrated Device for Space Saving

• First eight registers are 16C550 compatible

• 64-byte Transmit and Receive FIFOs

• Transmit and Receive FIFO Level Counters

• Programmable TX and RX FIFO Trigger Levels

• Automatic RTS/CTS or DTR/DSR Flow Control

• Selectable Hardware Flow Control Hysteresis

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

APPLICATIONS

• 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

• Automatic Xon/Xoff Software Flow Control with

Status Indicator

• Infrared (IrDA 1.0) Data Encoder/Decoder

• Programmable Data Rate with Prescaler

• Up to 6.25 Mbps Serial Data Rate at 5V

• 100-pin QFP Package (14x20x3 mm)
