Decoupling voltages DEC 1,DEC2,DEC4 - voltage out of spec

[Upright]

Hey there, I am using NRF52832 CIAA ( bga version)

I did some testing for internal DC DC ,

and found the following gaps

DEC1 - should be 1.3V , measured 1.27v

DEC2 - should be 0.9V measured 1.1v

DEC4 should be 1.3C measured 1.27V

any concern I should take into account here?

Hi there,

DEC1 - should be 1.3V , measured 1.27v

DEC2 - should be 0.9V measured 1.1v

DEC4 should be 1.3C measured 1.27V

What specification are you comparing your measurements with? Are you observing any specific issues?

regards

I see.

The description in the product specification is just to distinguish them from reach other. It's not meant that the voltage on the DEC1 will be 1V3 etc. The voltages on all DEC pins will have variation and it's dependent on the state of the regulators. If you're not seeing any specific issues linked to this then I would say that it's completely fine.
