Hello @Dlide.1​ ,

You can use ST-MCU-FINDER.

Best regards,

Well ST has sales offices and FAE (field application engineers)

Cube IDE/MX have parameter/pin fitting tools. The website has parametric search.

Various members of the forum have crystal balls, and tesseracts..

Beside the STMCUFINDER also look at the availability of parts before choosing a part. Allocation may interfere!

Getting the least popular parts, in the least popular form factors, might be a winning strategy this year.

If you have space for multiple pad/pin configurations, it will also provide some flexibility
