CAN with Flexible Data-Rate
CAN with Flexible Data-RateSpecificationVersion (released April 17th, 2012)FD Copyright 2011, Robert Bosch GmbH, Robert Bosch Platz 1, 70839 Gerlingen, GermanyApril 2012page 1 RecitalThe acceptance and introduction of serial communication to more and more applica-tions has led to increasing demand for bandwidth in CAN communication and causedsystem developers to look for alternative communication options in certain applications can be realized more comfortably with the new protocol CAN FDthat allows data rates higher than 1 MBit/s and payloads longer 8 bytes per FD shares the physical layer, with the CAN protocol as defined in the BOSCHCAN specification The frame format however, is different. There are two new con-trol bits in the CAN FD frame, the first enabling the new frame format with different datalength coding and the second optionally switching to a faster bit rate after the arbitrationis decided. New CRC polynomials are introduced to secure the longer CAN FD frameswith the same Hamming distance as in the proven CAN CAN FD frame format has been defined so that messages in CAN frame formatand in CAN FD frame format can coexist within the same network.
Within this specification the electrical driver/receiver characteristics of the Physical Layer are not defined so as to allow transmission medium and signal level implementa-tions to be optimized for their application. Within one network the Physical Layer, of …
