370uA current draw with all peripherals idlehttps://devzone.nordicsemi.com/f/nordic-q-a/101660/370ua-current-draw-with-all-peripherals-idleMy exact chip is N52810-QFAAD1-2145FM. I have pared down my hardware and software to the bare minimum: The hardware is essentially just the reference circuit with DC/DC regulator and external LF crystal , plus a very simple custom breakout board I amen-USTelligent Community 13Sun, 09 Jul 2023 15:37:16 GMTRE: 370uA current draw with all peripherals idlehttps://devzone.nordicsemi.com/thread/435362?ContentTypeID=1Sun, 09 Jul 2023 15:37:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4a2b2ae5-58af-4518-bc22-5bb361ca2dceItsAmelia<p>Update: I have made progress! When I do not enable the external 64MHz crystal, I get the expected (lower) current draw of ~1uA. I now realize there must be something wrong with the circuitry of my 64MHz crystal. The reason I got the low current draw in System OFF mode is because the HFCLK is disabled in OFF mode.</p> <p></p> <p>If anyone has suggestions for how I can identify and fix the issue with my circuitry, I would love to hear them! For what it&#39;s worth, the 32.768KHz crystal works perfectly fine, and does not have a large current draw.</p><div style="clear:both;"></div>
