CAN XL

CAN进化的下一步

Bosch CAN_XL Logo





CAN XL通过保持CAN协议的优势(例如无损仲裁的冲突解决),为高达20Mbit / s的数据速率提供了出色的解决方案。

关于比特率,CAN XL填补了CAN FD与100BASE-T1(以太网)之间的空白。

状态

CAN XL is standardized in the ISO 11898-1:2024 (CAN CC, CAN FD, CAN XL and CAN FD light).

In addition, many other CAN related standards will be updated simultaneously to support CAN XL. Examples are the CAN Conformance Test according to ISO 16845 and the physical layer which is released as ISO 11898-2:2024.
