"SYSTEM OFF" on NRF52810 no RAM retention using NRF Connect SDK

[CRNorris]

Hi,

I'm using NRF Connect SDK (Zephyr) with NRF52810.

I've got the System Off sample from the Zephyr tree working on my board, but I'm not sure what current draw to expect.

There are various typical values given in the Product Specification in the "Sleep" section, such as "ON_RAMOFF_EVENT", "ON_RAMON_GPIOTEPORT", does anyone know which one matches what the System Off sample is doing?

Also are these measurements taken with the internal DC/DC converter in operation, or the LDO?

I'd like to validate my measurements against the expected values.

Thanks!

Yes, these are just examples, and just the most common sleep scenarios are covered. The nRF52832, which has been around for a longer time has a few more, and you can see that the system OFF current is very similar whether it wakes on a GPIO or a RESET. I think it should be similar for a GPIO port event as well.

Best regards,

Simon
