ICCS 121P CAN Controller

The ICCS 121P CAN Controller is a part of the Intelligent Control and Command Systems (ICCS) product range, which can be easily implemented in your CAN network, or used as a standalone module.

The 16 bit processor NXP HCS12XEQ with an integrated co-processor has sufficient computing power to handle complex tasks. The two CAN and an optional LIN master interfaces allow the data exchange between independent bus systems or enable gateway / filter functions.

Application examples

  • Transmission of sensor values to the CAN bus
  • CAN to CAN gateway functions
  • LIN to CAN gateway function
  • Direct power supply of loads up to 2 A
  • Interface between switches and CAN bus
  • Lighting system handling
  • Protected power splices with built-in poly fuses

Programming

Programming the ICCS 121P CAN Controller is carried out using ICCS SDK Plus software.

In the development phase, we support you in the creation of programs.

If you prefer to create your parameters or create programs by yourself try our software development kit ICCS SDK Plus which you can borrow for three months free of charge.
