XR16C872 - DUAL UART

Datasheet Summary

Description

The XR16C8721 (872) is a dual universal asynchronous receiver and transmitter (UART) with a 1284 bi-directional parallel port and ISA Bus Plug-and-Play (PnP) interface.

The PnP interface supports auto configuration for desktop and embedded PC computers.

Features

  • of 128 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, transmit and receive FIFO counters, IrDA (Infrared Data Association) encoder/decoder, automatic RTS/CTS hardware flow control with selectable hysteresis and automatic software (Xon/Xoff) flow control. On board status registers provide interrupt priorities, receive data errors and modem status. Each channel has a programmable baud rate generator to provide data rates up to 460.8Kbps. The bidirection.

DISCONTINUED XR16C872 DUAL UART WITH 1284 PARALLEL PORT AND PLUG-AND-PLAY CONTROLLER DESCRIPTION August 2003 The XR16C8721 (872) is a dual universal asynchronous receiver and transmitter (UART) with a 1284 bi-directional parallel port and ISA Bus Plug-and-Play (PnP) interface. The PnP interface supports auto configuration for desktop and embedded PC computers. The host bus interface can also be configured to manually support standard PC addresses COM1-4 and LPT1-2. The parallel port is compatible to IEEE 1284 specification and supports Compatible Centronics, Extended Capability (ECP) and Enhanced Parallel Port (EPP) protocols.
