Before CAN bus gained popularity, vehicle wiring harnesses could contain miles of copper wire which significantly added to the cost and weight of the vehicle. CAN bus was originally designed to minimize copper wiring in automobiles by multiplexing electrical signals over a simple two wire network. By using a high-speed twisted pair cable, the amount of wire necessary to allow sensors, actuators and controllers to communicate was greatly reduced.

CAN FD product launches and roadmaps

CAN FD (Flexible Data-rate) is becoming a more prominent feature in many new and upcoming products. STMicroelectronics created a CAN FD starter kit and there was better performance in terms of screen content and speed in comparison to the classical CAN. In addition to this, Cypress, Microchip, and Renesas have also created operational CAN FD networks.
