https://devzone.nordicsemi.com/f/nordic-q-a/13284/tx-current-of-nrf51In the datasheet it is mentioned that the tx current is 10mA without DCDC. In our board, we are seeing a Tx peak current of 13.5mA. So my question is the does that quoted 10mA tx current include the 4mA current consumption by the ARM core, so that overallen-USTelligent Community 13Mon, 30 May 2016 09:01:48 GMThttps://devzone.nordicsemi.com/thread/50644?ContentTypeID=1Mon, 30 May 2016 09:01:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2a6d433b-af43-414b-a063-f6e6f9202841MARTIN FR<p>hello karlsen could ou please verify this point 10.5mA means 10.5mAh or can i take 0.0029mAh per hour</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50643?ContentTypeID=1Mon, 18 Apr 2016 12:20:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30fa6206-7fc2-4fe8-bbe1-263b1224191f&#216;yvind Karlsen<p>That should be correct.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50642?ContentTypeID=1Mon, 18 Apr 2016 12:15:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a41776e-5e88-400b-9ef8-49b415b93aa9Akhil<p>Hi, thanks for the prompt answer. During the advertising the the processor core is utilised by the softdevice and application code is not run at that time. From your answer what I infer is that (tx = 10ma) + (I_cpu = 4.1ma) = 14ma should be the expected current consumption during ble advertisement at 0dBm. Is that correct?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50641?ContentTypeID=1Mon, 18 Apr 2016 10:25:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:62890ba7-4ec1-486a-89be-a4cbe85335f3&#216;yvind Karlsen<p>Hi,</p> <p>As stated in the electrical specifications for the radio in the <a href="http://infocenter.nordicsemi.com/pdf/nRF51822_PS_v3.2.pdf">product specification</a>, the specified TX current is for TX only. Any additional currents could be peripherals or processing core.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
