Can VBB_USB_CAP pin be floating?

Hi fellow engineers,

the board I'm working has very limited room available. I plan NOT to use USB, so the question is: can I leave VDD_USB_CAP floating?

Thanks

Hello @giuseppescarpi,

You can keep USB pins floating. If  USB VBUS is not applied, there is no need to connect the VDD_USB_CAP.
