CAN FD light
Low-cost CAN FD protocol
Benefits
Filling the gap between CAN FD and Ethernet
New lost-cost CAN standard
Enable SDV (Software Defined Vehicle) for the end-node
Physical Layer
CAN FD light will be operable with all transceivers:
- Classical CAN up to 1Mbit/s
- CAN FD up to 2Mbit/s
- CAN SIC up to 5-8Mbit/s
Status
CAN FD light responder is standardized in the ISO 11898-1:2024 Annex A.
In addition, many other CAN related standards will be updated simultaneously to support CAN FD light.
Examples are the CAN Conformance Test according to ISO 16845 and the physical layer which is released as ISO 11898-2:2024.
Key Protocol Features
Net data rates up to 8Mbit/s
Reduced cost due to reduced complexity:
- CAN FD frame format with 11 Bit ID used, No 29 Bit ID,
- No arbitration,
- No error frames
- No BRS bit rate switch, ...
