CAN FD - A Brief Introduction
CAN FD (CAN with Flexible Data Rate) was developed by Bosch out of the necessity for greater bandwidth throughput in the automotive industry. Working closely with carmakers and other CAN experts, Bosch began development on the improved protocol in 2011, releasing it in 2012. CAN FD is an extension of the classical CAN protocol developed by Bosch in the 1980s (ISO 11898-1). CAN FD is compatible with existing CAN 2.0 networks, so new CAN FD devices can coexist on the same network with the existing CAN devices.
The enhanced CAN FD protocol addresses 3 main areas that are limitations with classical CAN.
Most of our standard CAN products are now available in CAN FD versions. For more information, please download this in-depth comparison of CAN FD and standard CAN.
