GENERAL DESCRIPTION

SMSC's COM20020-5 is a member of the family pin package, flexible microcontroller and media

of Industrial Network Controllers from Standard interfaces, eight-page message support, and

Microsystems Corporation. The device is a extended temperature range of the COM20020-5

special purpose communications controller for make it the only true network controller

networking microcontrollers and intelligent optimized for use in industrial and automotive

peripherals in industrial, automotive, and applications. Using an ARCNET protocol

embedded control environments using an engine is the ideal solution for factory

ARCNET® protocol engine. The small 24- automation applications because it provides a
