TMPN3150B1AF - TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC

The TMPN3150B1AFG is a Neuron Chip which configures 

LONWORKS nodes in combination with external memory. 

Neuron Chips have all the built-in communications and control 

functions required to implement LONWORKS nodes. These nodes 

may then be easily integrated into highly-reliable distributed 

intelligent control networks. 

The typical functions for this chip are explained below. 

FEATURES 

z I / O Functions 

• Eleven programmable I / O pins. 

• 

• 

• 

• 

• 

• 

• 

• 

• 

Two programmable 16-bit timers and counters built in. 

34 different types of I / O functions to handle a wide range of 

input and output. 

ROM firmware image containing pre-programmed I / O 

drivers, greatly simplifying application programs. 

( Stored in external ROM ) 

z Network functions 

Two CPUs for communication protocol processing built in. 

The communications and application CPUs execute in parallel. 

Equipped with a built-in LonTalk protocol which supports all seven levels of the OSI reference model with 

ISO. 

Highly reliable communication protocol is supplied as firmware. 

Built-in twisted-pair wire transceiver 

Equipped with communications modes and communication speeds which support various types of external 

transceivers. 

Supports twisted-pair wire, power line, radio ( RF ), infrared, coaxial cables and fiber optics. 

Communication port transceiver modes and logical addresses stored within the EEPROM. 

Can be amended via the network.
