https://devzone.nordicsemi.com/f/nordic-q-a/62440/the-specification-52840-cpu-running-currentHi , I have question about the specification of CPU running current. We did measure the current by PPK to force the CPU always running but the result is quite different with spec. At section 5.2.x.x , what is the current of the specification . en-USTelligent Community 13Thu, 11 Jun 2020 12:54:44 GMThttps://devzone.nordicsemi.com/thread/254497?ContentTypeID=1Thu, 11 Jun 2020 12:54:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:092e9933-b6d4-41cb-ad06-0987e5cfa571Stian R&#248;ed Hafskjold<p>Yes, the current is measured at VDD, not DEC1. The voltage is 3V.</p> <p>The current depends on what the CPU is doing. You can see several milliamps difference in consumption depending on the CPU tasks, RAM read/write, wait states, etc.&nbsp; You need to run the CoreMark code to reproduce the numbers.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/254385?ContentTypeID=1Thu, 11 Jun 2020 08:01:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea44702f-49a0-4441-b1d1-0c2179bcd225Turbo J[quote userid="73754" url="~/f/nordic-q-a/62440/the-specification-52840-cpu-running-current"]Is the current Idd which is related with Vdd?[/quote] <p>Yes, IF you have the DC/DC switching mode enabled.</p> <p>I don&#39;t think you can <em>measure</em> current at DEC1 pin.</p><div style="clear:both;"></div>
