https://devzone.nordicsemi.com/f/nordic-q-a/84991/query-regarding-peripheral-spi-twi-with-easy-dma-and-peripheral-power-consumptionHi, I working on nrf52840 DK with nrf5 SDK17. I tried to find out the power consumption of the peripheral(TWI/SPI) from the nrf52840 PS v1.7 document but it is not mentioned in it. So please let me know the power consumption of these peripheralsen-USTelligent Community 13Wed, 23 Feb 2022 10:41:36 GMThttps://devzone.nordicsemi.com/thread/354529?ContentTypeID=1Wed, 23 Feb 2022 10:41:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea7239c3-3ce8-4e0d-9b5d-8001f5be49e8AbhaySingh<p>Thanks Priyanka for the prompt reply.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/354383?ContentTypeID=1Tue, 22 Feb 2022 14:15:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:35900b6c-08ca-4757-b1e8-8699707f0397Priyanka<p>Hi Abhay,</p> <p>The current consumption for the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Ftwim.html&amp;cp=2_1_0_32_8&amp;anchor=unique_1658832437">TWIM</a>&nbsp;and <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fspim.html&amp;cp=2_1_0_30_6&amp;anchor=unique_190727990">SPIM</a> are 50uA.</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1645538913025v1.png" alt=" " /></p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1645538926848v2.png" alt=" " /></p> <p>If you are using this with the DMA, then the total consumption would be around 50uA + 1.5mA (DMA). But in case you are using other peripherals, that would also add up. So it depends on your power needs. You could take a look at the current consumption of all the peripherals from their Product Specification and make an estimate.</p> <p>Regards,</p> <p>Priyanka</p><div style="clear:both;"></div>
