https://devzone.nordicsemi.com/f/nordic-q-a/104786/power-consumption-vs-cacheDear Nordic, The table above shows that some nRF52 have a Cache (&quot;high end&quot;) and some have not. Except by performing tests, how to know the impact on performance, especially the current consumption? I&#39;ve check the datasheet and the dev zone anden-USTelligent Community 13Wed, 18 Oct 2023 15:16:22 GMThttps://devzone.nordicsemi.com/thread/451110?ContentTypeID=1Wed, 18 Oct 2023 15:16:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ba8caf03-383b-4b25-98ea-c364874379e3hmolesworth<p>In addition to Susheel&#39;s links you might find my reply here helpful. Since a cache miss uses more power than cache disabled a test is really the only way to get a measure of consumption differences. A while ago I did such a test, not sure where I put the results though.</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/68934/instruction-cache-i-cache-using-and-user-guide">instruction-cache</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/451053?ContentTypeID=1Wed, 18 Oct 2023 11:46:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2b86a4b9-c728-42c9-a59b-8747003c127aSusheel Nuguru<p>I do not think we have direct current consumption difference numbers for that but you can deduce that from the numbers given here.</p> <p><a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52840%2Fcpu.html&amp;cp=5_0_0_3_0_2_0&amp;anchor=unique_1608135448">CPU performance for nRF52840</a>&nbsp;and compare that with&nbsp;</p> <p><a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf52805%2Fcpu.html&amp;cp=5_6_0_3_0_0&amp;anchor=topic">CPU performance for nRF52805</a>.</p> <p>Interesting is to see the wait states that is relevant here in current consumption.</p><div style="clear:both;"></div>
