General 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.

Key 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.
