How to Configure (HW and SW) to have the least Power consumption when not transceiving (sleep mode)

[DevEng2021]

Hej!

I am trying to make a circuit / configure my SW for using the nRF5208 to have a small power consumption when not trainsceiving. Basically, I need my setup to have a low as possible current in sleep mode. Currently, my circuit is using around 0.6uA. Is it possible for this value to be even lower?

Setup:

Reference Schematic with external 32MHz Quartz

I was not sure which (HW / SW) is more important for this aspect. Please correct me if i put it in the wrong section or you need more information on the design

Best Wishes.

Hi,

A sleep current of 0.6 uA should be considered good. I do not expect you can reduce this much more (see Current consumption).
