STM32C092 and CAN FD transceiver selection

Nimit Vachhani · ‎2025-03-04

Greetings Everybody,

I am trying my hands with CAN FD. I have selected STM32C092RC for the same application as it has can fd port.

I was wondering if MCP2561/62 can fd transiver ic works with this controller. Please advice. I was also looking for schematic and cad resources for NUCLEO-C092RC board, but cant find. If anybody has the link for cad resources and schematics for NUCLEO-C092RC board then please do forward it.

Thanks in advance.

Hello @Nimit Vachhani ,

1- MCP2561 is OK. But please select the version having VIO pin. But becarefull this transceiver could not exceed 1Mb/s if you are planning to use CAN-FD data rate > 1Mb/s:

If you plan to exceed that bitrate, I may suggest MCP2562FD that can reach up to 8Mb/s.

2- For the schematic and cad resources for NUCLEO-C092RC board, they are not yet available on the ST website.

It will be available soon. For the moment, you can rely on the UM3353.

Edit: NUCLEO-C092RC has already a CAN-FD transceiver:

No need to add another CAN transceiver.

And this is the CAN connector (in green) correspond to CAN_H and CAN_L + GND (I think):

Hope that answers your questions.
