Neuron® 5000 Processor

The Neuron® 5000 processor implements the LonWorks® control networking standard ISO/IEC14908.1 in firmware. It interfaces to a wide variety of control networking transceivers including twisted-pair, radio frequency (RF), infrared (IR), fiber-optics, and coaxial — at a wide range of data rates.


  • Complies with ISO/IEC, ANSI, EN, and GB worldwide communications standards; Supports IEEE’s Joint Test Action Group (JTAG) testing standard for faster and easier testing   
  • Supports a variety of LonWorks applications, including building automation, elevator control, and industrial control; Supports up to 254 network variables and 127 aliases for creating sophisticated control-network applications that incorporate multiple types of devices with multiple control signals
  • Small-footprint offers a lower cost node; Interfaces to an inexpensive external serial EEPROM (and optional flash memory) for storing application code
  • Internal clock scales up to 80 MHz, providing fast network control response and provides fast response to events by letting you define interrupt conditions and how they will be handled

Neuron 5000 BSDL File

Series 5000 Tools Update Patch 1
If you are using the Echelon Series 5000 chips in production devices and plan to use the device NME file for programming external EEPROM memory devices, you should apply this update to your development tools.

Series 5000 Tools Update Patch 2
If you are using the Echelon Series 5000 chips in production devices and use the SCI I/O model on those devices, you should apply this update to your development tools, and then follow the usage instructions to ensure a reliable SCI I/O data stream. No other devices that use SCI I/O are affected.
