Hello again,

Sorry, but we do not provide any further details on these decoupling voltages, the actual voltage may differ depending operating mode, chip variation and trim values, they are not intended to be monitored or modified.

You can instead measure current consumption and do functional tests, and also for instance DTM test as part of a production test:

The background of question 2 is that the voltage of DEC1-DEC4 is mentioned in the specification register (should be a typical value?). They are 0.9V, 1.3V, 1.8V and 1.3V respectively

In our design process, the detected power is 1.09V, 1.25V, 1.79V, 1.25V;

Some have larger fluctuations, and some have smaller fluctuations.

But if you don't give us the requirements, it is difficult for us to judge whether the current state is OK.

Therefore, otherwise, please give the voltage fluctuation range of each pin of these four pins;

Otherwise, please help judge whether the above voltage is reasonable and whether it is risky

Above, thank you

Hello,

1. There is no support for feeding an external 32MHz signal to the nRF52832. So you need to have an external 32MHz crystal, and make sure the external 32MHz crystal fulfill the requirements listed here:
https://docs.nordicsemi.com/bundle/ps_nrf52832/page/clock.html#d910e8036

2. We do not provide that, since it's not intended to be used or fed externally. Make sure that the components used fulfill the requirements listed here (value and tolerance):
