ORKS
®
)
The TMPN3120E1M is a Neuron Chip which configures
L
ON
W
ORKS
nodes on a single chip.
Neuron Chips have all the built-in communications and control
functions required to implement L
ON
W
ORKS
nodes.
These nodes may then be easily integrated into highly-reliable
distributed intelligent control networks.
The typical functions for this chip are explained below.
