To improve CAN regarding bandwidth Bosch has specified the **improved CAN** data link layer protocol, called **CAN FD**. The idea behind CAN FD is that after the arbitration phase of classical CAN the data rate can be increased. The data bits are transferred with a higher bit rate than in the arbitration phase when a transmitter has won the bus arbitration. The speed is limited only by the CAN transceiver signal delay and the signal delay on the cable. \\ Besides the increased bit speed the new CAN FD allows date frames up to 64 bytes compared with the maximum of 8 bytes with **classical CAN**. | To improve CAN regarding bandwidth Bosch has specified the **improved CAN** data link layer protocol, called **CAN FD**.
