Hi all, Im currently designing my own pcb with a STM32WBA65CIU6 MCU in the UFQFPN48 package.
Im doing this for the first time (still gaining all the knowledg needed) and currently ran into the following problem:
I'm having trouble understanding the footprint and EDA symbol given for the STM32WBA65CIU6 on the product site and shop.
According to those, eg OSC32 are Pins 16 and 17:
But according to the data sheet and also in CubeMX the OSC32 should be pin 19 & 20:
Is this not a problem and can be solderd anyway? Also some other pin names are also missmatched :\
Thanks for the help :)

That is my guess as well. I always make my own symbols.
yes, the footprint is identical, just different pin names.

The datasheet and CubeMX are correct. The symbol seems to be for the SMPS non-USB package where the pin out is different.
Are you sure there isn’t another EDA symbol provided somewhere?

I dont seem to find any other options to select on the product page/store page. A google search also didnt get me further. Im guessing that the provided symbol is just a basic version and I have to ajust the pinout myself?
The footprint should still be the same size right, only depending on the package?
