Customer feedback they use CAN TJA1145AT/0Z & TJA1145AT/FD/0Z,It was all used according to the CAN FD function, and there were no problems。Therefore, what is the specific difference between FD and FD in model naming。There are still differences from the specifications, as shown in the figure。Thanks!

Dear Louis,

please refer to the section 7.3.2 in the TJA1145A datasheet. Depending on the CFDC bit setting the  TJA1145AT and the TJA1145AT/FD will behave same (CFDC=0=>error counter increments) or (CFDC=1) the TJA1145AT/FD will ignore the CAN FD frames=>error counter decrements.
