Using STM32L4R5ZI-P without external SMPS, connection to VDD12 pins?

[b.a.]

For a project, I could grab a few STM32L4R5ZI-P µC and am not sure what to connect to the 2 SMPS VDD12 pins when I do not want to provide external voltage but use the integrated LDO.

The datasheet is not quite clear on this scenario.

I have no augmented power saving needs, so the internal LDO will be fine for me.

So, can I just leave pins 70 & 142 floating, or do I have to apply some decoupling capacitors?

Cheers,

B.

you can leave the pins floating/unconnected

Thank you!

Is that valid for SMT32L496VGY also?

When I start debugging with stm32cubeide it goes in 0x1fxxxxx and I can't continue.

Don't cure about it, the problem was a wrong cpu solded on the board
