• Manufacturer Part Number: TMPN3120A20
• Description: TOSHIBA CMOS DIGITAL INTEGRATED CIRCUIT SILICON MONOLITHIC
• Manufacturer: TOSHIBA [Toshiba Semiconductor]

Main features of the 20MHz Neuron Chip
(In comparison with the TMPN3120E1M and TMPN3120A20M / U)
• Increased communication speed
• Shortened response time
• Increased IO object speed
• Development tool support
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.
• Equipped with a built-in LonTalk protocol which supports all seven levels of the OSI reference model with
• The ROM firmware image contains a complete network operating system, greatly simplifying application
• 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
• Communication port transceiver modes and logical addresses stored within the EEPROM.
The communications and application CPUs execute in parallel.

transceivers.
Supports twisted-pair wire, power line, radio ( RF ), infrared, coaxial cables, and fiber optics.
Can be amended via the network.
*1: This value applies to Single-Ended Mode only.
The maximum transmission speed has been increased two-fold.
1.25 Mbps→ 2.5 Mbps (*1)
The amount of time required from I / O input to I / O output has been greatly reduced.
Maximum speed 7ms →3~4 ms
The execution time for all objects has been halved.
Example) Serial I / O 9600bps
The current LonBuilder
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.
