STM32N657L0H3Q unused USB power pins?

[foc]

Hi all,

I want to design STM32N6 based board and in this board I don’t have any 3.3V supply so what should I do the unused USB power pins? Should I left unconnected or connect them to GND?

 

Thanks and regards

Hi ​@foc 

I will check internally and get back to you ASAP. It seems the app note doesn’t specifically specify this. I assume we should have no constraints.
