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

I'm sorry, but how pins are connected internally within the chip is proprietary information, so I can't help you out there Pierre. I strongly recommend that you do supply pin 32 with power however, as it is necessary to power all VDD pins in order to ensure that the nRF operates correctly. 

Best regards,

thank you anyway Simon , the tricky thing is that the application board is certifiied by CE test , everything is OK , so if I change the layout , we need to remake the CE certification ,

so I m wondering if there is no risk to leave this pin unconnected
