TMPN3120FE3M/U
TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
TMPN3120FE3M, TMPN3120FE3U
Neuron ® Chip
For Distributed Intelligent Control Networks (LONW 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
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 (*1)
Weight : 1.1g (Typ.)
Weight : 0.6g (Typ.)
*1: This value applies to Single-Ended Mode only.
• Shortened response time
The amount of time required from I / O input to I / O output has been greatly reduced.
Maximum speed 7 ms → 3~4 ms
