MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Neuronâ Chip Distributed
Communications and Control
Processor
The MC143120 is a communications and control processor which enables the
development of interoperable products. It provides systems designers with many
features to accelerate product development for distributed sense and control
applications. Services at every layer of the OSI networking model are implement-
ed in the included LonTalkâ Þrmware-based protocol and are easily and option-
ally invoked. In addition, 34 I/O models are integrated with hardware to provide
simpliÞed sense and control device interfacing.
The MC143120 is designed for maximum clock operation of 10 MHz over a
temperature range of Ð 40 to + 85°C including EEPROM writes.
