Next step in CAN evolution
CAN XL provides a superior solution for data rates up to 20Mbit/s by maintaining the advantages of the CAN protocol like collision-resolution by non-destructive arbitration.
With respect to the bitrate, CAN XL fills the gap between CAN FD and 100BASE-T1 (Ethernet).
CAN XL protocol controllers are also able to perform Classical CAN and CAN FD communication.
CAN XL is specified by CiA 610-1 (CAN in Automation). CAN XL is currently standardized as part of ISO11898-1.
In addition, many other CAN related standards will be updated simultaneously to support CAN XL. Examples are the CAN Conformance Test according to ISO16845 and the physical layer.
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
