T2M Automotive CAN XL Controller IP

CAN XL Controller IP

Description and Features

The CAN XL IP represents a breakthrough, bridging the gap between CAN FD and 100Mbit Ethernet. Supporting data rates up to 20 Mbit/s and data fields up to 2048 bytes, it surpasses previous standards. It also offers flexibility with higher layer protocols and Ethernet frame tunneling.


Maintaining the reliability of the CAN protocol, this solution integrates seamlessly while meeting evolving needs. It is backward compatible with Classical CAN, CAN FD, and CAN XL. External transceiver hardware is required for physical connectivity, with CAN transceivers for bitrates below 10Mbps and CAN SIC XL transceivers for higher bitrates.


CAN XL implementation includes a single or dual-ported Message RAM and integrates with the host CPU via a 32-bit Generic Interface, compatible with popular interface wrappers.


Available in Basic and Safety-Enhanced versions, the latter is developed as an ISO26262-10 Safety Element out of Context with necessary safety mechanisms and documentation. Third-party audits ensure compliance with ASIL-B requirements. Comprehensive FMEDA analysis is provided for integration and system-level safety analysis, making it suitable for Automotive Safety Systems and higher ASIL level readiness.
