COM20019 Datasheet, PDF (2/81 Pages) SMSC Corporation – Low Cost ARCNET (ANSI 878.1) Controller with 2K x 8 On-Board RAM

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.
