Description

The TMPN3120B1AM is a Neuron Chip which configures LONWORKS nodes on a single chip.

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.
