Features

to accelerate product development for distributed sense and control applications. Services at every layer of the OSI networking model are implemented in the included LonTalkâ Þrmware-based protocol and are easily and optionally 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. ¥ Three 8-Bit Pipelined Processors for Concurrent Processing of Application Code and Network Packets ¥ 11-Pin I/O Por.
