Device Overview

Summary

Microchip's COM20019I 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 flexible microcontroller and media interfaces, eight-page message support, and extended temperature range of the COM20019I make it the only true network controller optimized for use in industrial, embedded, and automative applications. Using an ARCNET protocol engine is the ideal solution for embedded control applications because it provides a token-passing protocol, a highly reliable and proven networking scheme, and a data rate of up to 312.5 Kbps when using the COM20019I.
