https://devzone.nordicsemi.com/f/nordic-q-a/66395/idle-current-in-online-power-calculatorI&#39;ve been experimenting with your online power calculator: https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble for NRF52840. I see that the idle current is shown as 2.7 uA. What exactly is that current -- is that radio idleen-USTelligent Community 13Thu, 01 Oct 2020 07:33:54 GMThttps://devzone.nordicsemi.com/thread/272429?ContentTypeID=1Thu, 01 Oct 2020 07:33:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29675e49-5a65-491e-96c1-bfee04f022dcMartin Lesund<p>The Idle current of 2.7uA is derived by adding the following&nbsp; below.</p> <p>&nbsp;<img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/4520.pastedimage1601537582242v1.png" alt=" " /></p> <p>Pretty close to 2.7uA.</p> <p>&nbsp;<img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/3542.pastedimage1601537598680v2.png" alt=" " /></p> <p>&nbsp;</p> <p><strong>RTC</strong></p> <p>&nbsp;<img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/3554.pastedimage1601537611892v3.png" alt=" " /></p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/7840.pastedimage1601537623354v4.png" alt=" " /></p> <p>You can see the difference between the two different LF clock options. The 32Khz RC is higher which you can see by switching the LC clock option back and forth.</p> <p>Using this RC option is ok if one can handle the extra bit of current consumption and wishes to save some board space, cost and free up two GPIOs.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/272390?ContentTypeID=1Wed, 30 Sep 2020 18:49:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4beb7a28-87b6-40a1-ba12-528d485a5eb3David<p>Thanks -- I&#39;m aware of the sleep current spec.&nbsp; I&#39;m asking what is meant by the &quot;idle current&#39; shown in the power simulator and how that is calculated.&nbsp; I cannot seem to reconcile the 2.7uA shown in the power calculator.&nbsp; Where is that number coming from?&nbsp; Where is it in the datasheet?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/271656?ContentTypeID=1Mon, 28 Sep 2020 06:44:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f3b9e528-be70-43a8-8d97-d98f4aa81033Martin Lesund<p>Hi David,<br />You can find the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2F_tmp%2Fgraviton%2Fautodita%2FCURRENT%2Fparameters.i_sleep.html&amp;cp=4_0_0_4_1_0_0" rel="noopener noreferrer" target="_blank">sleep current in the product spec. here.</a></p><div style="clear:both;"></div>
