STM32H562AGI FDCAN2 available or not?

[userly]

I am using a stm32h562agi6 and configured fdcan2. It works!

But then I wanted to create a zephyr os project and saw that there the fdcan2 is not available for stm32h562xx in general. I did some investigations and also the datasheet actually states that fdcan2 is not available (features and peripheral counts). I basically read everywhere that it has only one fdcan peripheral. I use PB5 and PB6 which are only listed for FDCAN2. 
 

So what is true now? Is it because it’s a UFBGA169?

It is very common (not just with ST)  that many different MCU part numbers are actually the same silicon chip inside.

On part numbers where the FDCAN2 is not listed as present, that could mean that it has either been tested and found not to meet (all) specs, or has not been tested at all.

So you might be lucky and find that it manages to “work” in your limited application conditions - but you should not rely on that for production!

Similarly chips are often found to have more memory than reported in the datasheet….

 

So what is true now? 

You should take what the datasheet says as definitive.

(subject, always, to the Errata)

Hello ​@userly and welcome to the ST community;

The answer to this question is provided in the product datasheet:

So STM32H562AI/G have only one FDCAN instance which is FDCAN1. FDCAN2 is not available.

I think it’s a technical constraint to not have FDCAN2 on that package.

Perfect thank you for the clarification!
