MC143150B2
Neuron Chip Distributed
Communications and Control
Processor
The MC143150B2 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 con-
trol applications. Services at every layer of the OSI networking model are imple-
mented in the IC, including the LonTalk rmware-based protocol, which are
easily and optionally invoked. In addition, 34 I/O routines are integrated within
hardware to provide simplied sense and control device interfacing.
The MC143150B2 is designed for operation over a temperature range of – 40
to + 85
°C.
10 MHz Crystal Operation — Full Function Compatibility with MC143150B1FU1
Three 8-Bit Pipelined Processors for Concurrent Processing of Application
Code and Network Packets
11 I/O Pins are Customer Programmable or the 34 Models Available in the
LonBuilder Development Tool May be Used
Two 16-Bit Timer/Counters for Measuring and Generating I/O Device
Waveforms
5-Pin Communications Port that Supports Direct-Connect and Network
Transceiver Interfaces
2048 Bytes of Static RAM for Buffering Network Data and Storing Network
Variables
512 Bytes of EEPROM with On-Chip Charge Pump for Flexible Storage of
Address and Binding Data
Programmable Pull-Ups on Pins IO4 – IO7 and 20 mA Sink Current on Pins IO0 – IO3
Unique 48-Bit ID Number in Every Device to Facilitate Network Installation
and Management — ID Number Stored Redundantly for Guaranteed 20-Year
Data Retention
Low Operating Current: 16 mA (Typical) @ 10 MHz Frequency
8 mA (Typical) @ 5 MHz Frequency
Sleep Mode Operation Reduced Current Consumption (15
A Typical)
On-Chip Low Voltage Inhibit (LVI) Circuit with Programmable Sleep Mode
On/Off Operation (Trip Point 4.1
± 0.3 V)
0.8
Design Process
Transceiver Pins Allow Network Connections Without Use of External Relays
Motorola Recommends the Use of an External LVI.When Using External
Flash Memory, an LVI with Extended Delay Time Should be Used, i.e.,
