Technical Article (1/2): CAN XL Provides the Basis for Seamless Cooperation With Ethernet

Transformational Change in Automotive Communication Systems

Just a few years after the market launch of CAN FD, a new CAN variant, CAN XL, is on the start – sometimes viewed with a little suspicion. In fact, CAN XL owes less to the marketing strategy of electronics suppliers than it does to the dynamic development in automotive electronics over the last few years. In particular, the advent of automotive Ethernet with IP technologies is changing some things fundamentally. Currently, service-oriented communication is establishing itself in the vehicle parallel to signal-based communication. In this context, CAN XL provides the basis for efficient cooperation between IP technology and classic, signal-based communication. With data transmission speeds of up to 10 Mbit/s, it closes the gap between CAN FD and 100-Mbit Ethernet (100BASE-T1).
