I see the following description in TJA1042 datasheet:
The TJA1042 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
I want to know if TJA1042 supports FD?
Yes,it supports!
