Dear @Ranjeet Singh​ ,

Yes, this is possible FD-CAN is compatible with CAN2.0 and you can enable STM32G0 to work in CAN2.0 legacy mode. For more details on STM32 CAN and FD-CAN implementations and Differences see this Application Note : AN5348

All FD-CAN and XD-CAN devices have a compatibility mode, and interoperate with standard CAN devices.

Except for some niches, market penetration of these new highspeed CAN standard is not very high.
