nRF52810(QFN32) - pin 32 - vdd

[pierre12345]

in application design , this pin is not connected to VDD , but application board works well ,

application's power range is 2.2V - 3.3V (AAA batteries), max current consumption is around 7mA.

so is there a risk for application?

and what is the role of this pin ?

Hi Pierre

I'll ask internally for more information regarding your situation, but I would prepare for having to make a new layout and doing the certification process over again if I was you, to be honest. It might take a few days before I get a reply, so please be patient. I will update you as soon as I know something.

EDIT: What state is pin 32 in? Is it connected to GND or just not connected (left floating)?

Best regards,

Simon

thank you a lot Simon, this reply matters a lot for us , not only for application itself , but also for satisfiying our end users . 

For actual status , the PIN32 is just connected a capacitor of 4.7uF.

So fat as I can tell , I suppose that this pin is mainly for DCDC regulator part (for the reasons: 1\ it is next ro DCDC filter pins, 2 its capacitor is 4.7uF , not 100nF as with other VDD pins; it seems that it is for high voltage input) 

anyway , please let me know if you have any clue

best regards
