I am developing a design with a STM32WLE5JCI6TR MCU. Regarding the pin PB0-VDDTCXO, if I am not using a TCXO in my design, should I simply connect this pin to groud?

That would depend on if other code sets the pin high, assuming that will power a TCXO, then you're basically shorting that to ground, pulling maximal current through the transistor. Doesn't seem like a good plan to me.

Hi,

you can simply use it as any GPIO (PB0)

Okay! Thanks both for the reply.
