CAN -FD
What is CAN -FD CAN-FD is a communication protocol based on CAN> CAN-FD is an improvement over CAN. Modern CAN controllers support both CAN and CAN-FD frames Note: CAN-FD is not a substitute for CAN protocol. A Single automotive network can have both CAN frames and CAN-FD frames. so CAN-FD protocol must be compatible with CAN protocol. Advantages of CAN-FD over CAN Data: CAN -FD frame can carry up to 64 bytes of data whereas CAN carries 8 Bytes Speed: CAN-FD frame maximum speed up to 5Mbps whereas CAN frame up to 1Mbps. Note: CAN-FD has dual speed (bit rate ). Data and CRC fields can be transmitted at a higher speed. The remaining fields of the frame will be transmitted with a lower speed, the same as the CAN speed. The orange colour field will transmit at a lower speed. and the Blue colour field will transmitted at a higher speed. CAN and CAN FD use the same SOF –a single “dominant” bit Little difference betwee...
