SDK15.0 QSPI Power consumption problem

[jermi]

I use the QSPI(SDK15.2) of NRF52840 to read and write FLASH. Every time I open QSPI function, QSPI is closed after writing flash, but after close QSPI,
there will be occasional 600UA power consumption, the probability is 5%;Debugging found that if you close the QSPI and then call the AD conversion function "nrfx_saadc_sample_convert",
the power consumption can basically return to normal, what is the reason for this, how to solve.
thinks!!

Hi, can you please post the code you are using to initialize, transfer data and close the QSPI? Are you using the SDK drivers? I'm not able to reproduce this with the QSPI example in the SDK.

In general the 600uA current consumption indicates that the HF clock is still running after the transfer because it has been incorrectly disabled.
