XR16C872

DUAL UART WITH 1284 PARALLEL PORT

AND PLUG-AND-PLAY CONTROLLER

DESCRIPTION

August 2003

TheXR16C872¹(872)isadualuniversalasynchronousreceiverandtransmitter(UART)witha1284bi-directional

parallelportandISABusPlug-and-Play(PnP)interface.ThePnPinterfacesupportsautoconfigurationfor desktop

and embedded PC computers. The host bus interface can also be configured to manually support standard PC

addresses COM1-4andLPT1-2.TheparallelportiscompatibletoIEEE1284specificationandsupportsCompatible

Centronics, Extended Capability (ECP) and Enhanced Parallel Port (EPP) protocols. The UARTs are software

compatibletoindustrystandard16C550andincludeenhancedfeaturesof128bytesoftransmitandreceiveFIFOs,

programmable transmit and receive FIFO trigger levels, transmit and receive FIFO counters, IrDA (Infrared Data

Association)encoder/decoder,automaticRTS/CTShardwareflowcontrolwithselectablehysteresisandautomatic

software(Xon/Xoff)flowcontrol.Onboardstatusregistersprovideinterruptpriorities,receivedataerrorsandmodem

status. Each channel has a programmable baud rate generator to provide data rates up to 460.8Kbps. The bi-

directional parallel port can be configured as a general purpose input/output interface or connected to a printer or

portable storage devices. The 872 operates on a single +5V and +3.3 power supply. It is available in a small 100-

pin QFP package and offers commercial and industrial temperature ranges. The chip is fabricated in an advanced

CMOS process to reduce power consumption.

FEATURES
