CAN XL
Next step in CAN evolution
Status
CAN XL is standardized in the ISO 11898-1:2024 (CAN CC, CAN FD, CAN XL and CAN FD light).
In addition, many other CAN related standards will be updated simultaneously to support CAN XL. 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 20Mbit/s
- Large data fields with up to 2048 byte enable the use of higher layer protocols like IP (Internet Protocol) and even the tunneling of complete Ethernet frames
- Interoperability with CAN FD for mixed FD/XL networks
Physical Layer
CAN XL will be operable with all transceivers:
CAN XL will be operable with all transceivers:
- Classical CAN up to 1Mbit/s
- CAN FD up to 2Mbit/s and CAN FD-SiC up to 5-8Mbit/s
- CAN XL up to 20 Mbit/s
