CAN 协议

CAN XL 协议

CAN XL(具有扩展长度的控制器局域网络)通过保持 CAN 协议的优势(如通过非破坏性仲裁解决碰撞问题),为高达 20Mbit/s 的数据传输速率提供了卓越的解决方案。它将每个 CAN 帧的数据字节数扩展到 2048 字节。

CAN XL 以高达 20 Mbit/s的比特率填补了 CAN FD 和 100BASE-T1(以太网)之间的空白。CAN XL 协议控制器也能进行经典 CAN 和 CAN FD 通信。

CAN XL

CAN FD 协议

CAN FD 协议

博世在2012年推出CAN FD(具有灵活数据速率的CAN),以克服经典CAN 1 Mbps的比特率限制,并将每个CAN帧的数据字节数从最多8个扩展到最多64个,从而缩小经典CAN和其他协议的差距。这是通过修改CAN帧格式实现的,其中比特率可以在CAN帧内切换到更快的值,并通过一个新的数据长度编码。

CAN FD符合ISO11898-1:2015标准。CAN FD协议的控制器也能够进行经典的CAN通信。

CAN FD light 协议

CAN FD Light 是 CAN FD 的轻量化版本,旨在用于低成本应用,采用单个主控(Commander/Master)控制器和多个从属(Responder/Slave)控制器。

对于 CAN FD Light 从属(Slave)设备,无需外部晶振,从而降低成本。
现有的 CAN FD / XL IP 可用于 CAN FD Light 主控(Master)。
