COM20019
(Rev.:2000)

Low Cost ARCNET (ANSI 878.1) Controller with 2K x 8 On-Board RAM

SMSC -> Microchip 

proven networking scheme, and a data rate of up

to 312.5 Kbps when using the COM20019.

A token-passing protocol provides predictable

response times because each network event

occurs within a predetermined time interval, based

upon the number of nodes on the network. The

deterministic nature of ARCNET is essential in

real time applications. The integration of the 2Kx8

RAM buffer on-chip, the Command Chaining

feature, the maximum data rate, and the internal

diagnostics make the COM20019 the highest

performance embedded communications device

available. With only one COM20019 and one

microcontroller, a complete communications node

may be implemented.
