TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC

TMPN3120A20M, TMPN3120A20U

Neuron

Chip

For Distributed Intelligent Control Networks (L

ORKS

)

The Neuron Chip (TMPN3120A20M and TMPN3120A20U) provides
double the performance of previous Neuron Chips. It supports a
response time of 3 to 4 ms across a L

ORKS

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.
Neuron Chips have all the built-in communications and control
functions required to implement L

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.

Main features of the 20MHz Neuron Chip
(In comparison with the TMPN3120E1M and TMPN3120A20M / U)
· Increased communication speed

The maximum transmission speed has been increased two-fold.
1.25 Mbps 2.5 Mbps (*1)

*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 7ms 3~4 ms

· Increased IO object speed

The execution time for all objects has been halved.
Example) Serial I / O 9600bps

Parallel I / O 1.2µs / byte

· Development tool support

The current LonBuilder

and NodeBuilder

development tools can be used to develop applications for the

TMPN3120A20M and TMPN3120A20U (L.B ver. 3.0 or 3.01 is needed). Updated symbol table files for
the Neuron Chip firmware are available from Echelon. If your application requires a 20MHz input clock,
a utility program available from Echelon may be used to convert the programmer files.

* The conversion utilities can be obtained from the Echelon Web Site at http://www.echelon.com.

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.

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.

· The ROM firmware image contains a complete network operating system, greatly simplifying application

programs.

· Built-in twisted-pair wire transceiver with improved common mode and drive current capabilities.
· Equipped with communications modes and communication speeds which support various types of external

transceivers.

Other functions

· Application programs are also stored within the EEPROM.

Can be updated by downloading over the network.

· Built-in watch-dog timer.
· Each chip has a unique ID number.

Effective during the logical installation of networks.

· Low electrical consumption mode supported with a sleep mode.
· Built in Selectable Reset time

Prolongs the power-ON reset time for at least 50ms and keeps the operation stable during that time. The
reset time can be selected 50ms delay mode or 3clock delay mode by program after the device is in power-ON.

· High-impedance communication port ( CP0 to CP3 )

The Communication port pins ( CP0 to CP3 ) attain high impedance. This eliminates the need for an external
relay.

· Built-in low-voltage detection circuit.

Prevents in correct operations and writing errors in the EEPROM during drops in power voltage.
An external LVD must be used to assert reset at power supply voltage below 4.5 V if Neuron Chip is operated
at 20 MHz.

· Programmable LVD (Low Voltage Detection) circuit.

LVDin pin is prepared in order to make it reset on arbitrary voltage.

· Firmware version 9.
