CAN protocol extension for more data throughput
Application & Technical Summary
CAN FD (CAN with Flexible Data-rate) was introduced by Bosch in 2012 to overcome the Classical CAN’s bit rate limitation to 1 Mbps and to expand the number of data bytes per CAN frame from up to 8 to up to 64, thereby closing the gap between Classical CAN and other protocols. This is achieved by a modified CAN frame format where the bit rate can be switched to faster value inside the CAN frame and by a new data length coding. CAN FD is standardized as ISO11898-1:2015. CAN FD protocol controllers are also able to perform Classical CAN communication.
- Average bit rates up to 2-4 Mbit/s, depending on application
- Data fields with up to 64 bytes
