Neuron ^® Chip
For Distributed Intelligent Control Networks (L_ONW_ORKS^®)
The Neuron Chip (TMPN3120FE3M and TMPN3120FE3U)
provides double the performance of previous Neuron Chips. It
supports a response time of 3 to 4 ms across a LONWORKs
Network and has double the input / output (I / O) performance of
the previous Neuron Chip in terms of both response time and
data transmission speed.
The Neuron Chip (TMPN3120FE3M and TMPN3120FE3U)
features an extra single-chip memory in the form of 2 Kbytes
EEPROM, 2 Kbytes SRAM and 16 Kbytes ROM. It is therefore
suitable for applications which require complex operations and
high speed communication control.
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
l Main features of the 20 MHz Neuron Chip
( In comparison with the TMPN3120E1M and
TMPN3120FE3M / U )
· Increased communication speed
The maximum transmission speed has been increased
two-fold.
1.25 Mbps → 2.5 Mbps
Weight : 1.1g (Typ.)
Weight : 0.6g (Typ.)
· Shortened response time
The amount of time required from I / O input to I / O output hasbeen greatly reduced.
Maximum speed 7 ms → 3~4 ms
· Increased IO object speed
The execution time for all objects has been halved.
Example ) Serial I / O 9600 bps
Parallel I / O 1.2 µs / byte
