CAN XL, the third generation of the CAN protocol, builds upon the well-known arbitration principle used in CAN CC and CAN FD. It introduces additional features, such as an extended payload length of up to 2048 byte and configurable data throughput rates of up to 20 Mbit/s. CAN XL retains the robustness and reliability of CAN CC and CAN FD, while enables integration into Ethernet environments through mapping Ethernet frames into CAN XL frames. CAN XL knowledge provides more technical details.
NOTE: For a summary of CAN XL key features consider Vector's CAN XL poster, as well.
CAN XL is applicable in various domains such as:
CAN XL can be used with different transceiver technologies:
