X_CAN | Protocol controller IP for Classical CAN / CAN FD / CAN XL

CAN XL provides a superior solution for data rates of 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).

Benefits

Support of Classical CAN, CAN FD, and CAN XL

Bit rate of up to 8Mbit/s, user configurable

Message storage in system memory of SoC

Physical Layer

Mixed CAN FD / XL networks

CAN XL will be operable with all CAN transceiver types:

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

Status

The specification of the CAN XL protocol and physical layer is released by the ISO (International Organization for Standardization).

The ISO 11898-1:2024 specifies the CAN protocols (CAN CC, CAN FD, CAN FD light and CAN XL)
The ISO 11898-1:2024 specifies the CAN transceivers (CAN HS, CAN FD, CAN SIC, CAN SIC XL)

In addition, many other CAN related standards will be updated simultaneously to support CAN XL. E.g. the CAN Conformance Test according to ISO 16845.
