https://devzone.nordicsemi.com/f/nordic-q-a/12523/nrf52-ram-bank-currentPlease correct me if I&#39;m wrong but my understanding is that unused RAM banks can be disabled to reduce quiescent current. My first question is what is the current consumption of a RAM bank? How is turning off the RAM banks affected by PAN-15en-USTelligent Community 13Wed, 16 Mar 2016 08:25:05 GMThttps://devzone.nordicsemi.com/thread/47492?ContentTypeID=1Wed, 16 Mar 2016 08:25:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0a6a04b2-b362-4117-bbad-d0ff295f94c4H&#229;kon Alseth<p>No problem, always happy to help :-)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/47491?ContentTypeID=1Tue, 15 Mar 2016 23:01:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0ecc40cb-109e-46f8-8f13-1eb3ab2479e7WestCoastDaz<p>Hakon,</p> <p>Thanks for the quick answer!</p> <p>Cheers, Darren</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/47490?ContentTypeID=1Mon, 14 Mar 2016 07:59:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:47918278-b71d-4a2a-84f1-11a80c80e56eH&#229;kon Alseth<p>Hi Darren,</p> <ol> <li> <p>The consumption is 20 nA per 4k block while in systemon/systemoff power mode: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.0/power.html?cp=1_2_0_16_9#unique_1289926025">infocenter.nordicsemi.com/.../power.html</a></p> </li> <li> <p>Errata #15 states that RAM.POWERSET[x] and RAM.POWERCLR[x] is unreliable for read operation. You can still use these to control the RAM blocks, but you must use RAM.POWER to read the current state of your RAM.</p> </li> <li> <p>This depends on if you use all of the RAM or not. If there are chunks of RAM that you do not use (and this has been verified), then you can safely turn them off.</p> </li> </ol> <p>Cheers, Håkon</p><div style="clear:both;"></div>
