Hi,
For a meter application with battery, I want MCU is sleeping but comparator still working to count a pulse input (freq <100khz)
Can Nordic IC can support this idea and how power consumption at this stage?
Thanks,
Brgs,
Eric.

Hi,
Do you want the Comparator to wake up the device from sleep?

I will have a look and see what I can find on this.
Will get back to you in January.

Hi,
could you share the example code for this ?
due to 54L05 sample is not available right now, I will test on nrf52833-DK.

I removed the spam comment, which removed your answer as well. To repost your questions here:

Got an answer for this one:
Expected current consumption for System On Idle mode (32KB RAM retention) with COMP enabled in Low, Normal and High power mode (MODE:SP) is 44uA, 46uA and 50uA at 25 degrees Celsius and 3.0 volt supply voltage respectively.

To use nrfx in nRF Connect SDK, see the nrfx use example.
