GENERAL DESCRIPTION

SMSC's COM20019 is a member of the family of

Embedded ARCNET Controllers from Standard

Microsystems

Corporation.

The device

is a

general purpose communications controller for

networking

microcontrollers

and

intelligent

peripherals

in

industrial,

automotive,

and

embedded control

environments

using

an

ARCNET protocol engine. The small 24 pin

package,

flexible

microcontroller

and

media

interfaces, eight- page message support, and

extended temperature range of the COM20019

make it the only true network controller optimized

for use in industrial, embedded, and automotive

applications. Using an ARCNET protocol engine

is

the

ideal

solution for

embedded

control

applications because it provides a deterministic

token-passing protocol, a highly reliable and
