CAN FD

CAN FD was created to provide increases in bandwidth within automotive and industrial networks. The CAN FD protocol has taken application software closer to "real time" through the minimization of delays between instruction and transfer of data (latency) and higher bandwidth. CAN FD  provides more storage capacity in the CAN Bus data frame. While classic CAN can hold 8 bytes of data within the CAN frame, CAN FD can hold up to 64. This is achieved through a decrease in relative overhead and improvements to software simplicity and efficiency when transmitting large data objects. CAN FD also has reduced the number of undetected errors by increasing CRC-algorithm performance.  CAN FD is compatible with existing CAN 2.0 networks, allowing the new protocol to function on the same network as classic CAN. CAN FD has been estimated to transmit data up to 30 times faster than classic CAN. More Information...
