SECTION 1 INTRODUCTION The Motorola MC143150 and MC143120 Neuron Chips are sophisticated VLSI devices that make it possi- ble to implement low–cost local operating network applications. Through a unique combination of hard- ware and firmware, they provide all the key functions necessary to process inputs from sensors and control devices intelligently, and propagate control information across a variety of network media. The MC143150 and MC143120, with the LonBuilder® Developer’s Workbench or the NodeBuilder™ Development Tool, offer the system designer: • Easy implementation of distributed sense and control networks • Flexible reconfiguration capability after network installation • Management of LonTalk® protocol messages on the network • An object–oriented high level environment for system development ADDRESS DATA R/W E MAC PROCESSOR NETWORK PROCESSOR APPLICATION PROCESSOR RAM 2 KBYTES EEPROM 512 BYTES NETWORK COMM.

It provides systems designers with many fea- tures to accelerate product development for distributed sense and control applications. Services at every layer of the OSI networking model are implemented in the included LonTalk™ firmware–based protocol and are easily and optionally in- voked. In addition, 34 I/O models are integrated with hardware to provide simplified sense and control device interfacing. The MC143120 is designed for input clock operation up to and at 10 MHz over a temperature range of – 40 to + 85°C including EEPROM writes. • Three 8–Bit Pipelined Processors for Concurrent Processing of Application Code and Network Packets • Eleven–Pin I/O Port Programmable in 34 Modes for Fast Application Program Development • Two 16–Bit Timer/Counters for Measuring and Generating I/O Device Waveforms • 5–Pin Communications Port That Supports Direct Connect and Network Transceiver Interface • 1024 Bytes of Static RAM for Buffering Network and Application Data • 512 bytes of EEPROM with on–chip charge pump for address, binding data, and application code • Programmable Pull–Ups on IO4 – IO7 and 20 mA Sink Current on IO0 – IO3 • Unique 48–Bit ID Number Stored Redundantly in Every Device • 10 Kbyte ROM • 32–Pin SOG Package • Low Operating Current 15 mA (Typical) at 10 MHz Frequency 3 mA (Typical) at 625 kHz Frequency • Sleep Mode Operation Reduced Current Consumption (15 µA Typical) • 0.8µ Design Process • Redundant 48–Bit ID for Longer Reliability SOG CASE 855–01 BLOCK DIAGRAM NETWORK PROCESSOR MEDIA ACCESS PROCESSOR APPLICATION PROCESSOR 1024 BYTES RAM 512 BYTES EEPROM 10K BYTES ROM DATA BUS (0:7) ADDRESS BUS (0:15) COMM PORT I/O CLOCK CONTROL CP4 CP0 IO10 IO0 CLK 1 CLK 2 SERVICE RESET This document contains information on a new product under development.
