STM32G0 come with only one VDD/VSS pair. Some ST patent, that I do not have a reference to at the moment, talk about a patented power distribution architecture. I sucpected substantial on-chip capacitance by that structure.
With the SO8 G031 I have at hand, I can measure around 1100 pF between VDD/VSS with a smart tweezer.
With a L412, probably without that special power distribution structure, I can also measure about 940 pF
Just if somebody is interested.
I would like those values mentioned as typical value in the datasheet.

I would like to know the minimal bypass capacitance for reliable low speed, low power operation on the G031
