https://devzone.nordicsemi.com/f/nordic-q-a/23971/nrf52-n52832-downgradingHi everyone, I was wondering if it is possible to change clock frequency on n52832 manually. Datasheet (from n52832) says that it is automated distributed but do you know about &quot;downgrading&quot; clock to obtain maximalize power saving when you do not needen-USTelligent Community 13Tue, 01 Aug 2017 14:55:36 GMThttps://devzone.nordicsemi.com/thread/94368?ContentTypeID=1Tue, 01 Aug 2017 14:55:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:473f224c-c09c-4d43-9f39-5915614fc19fNguyen Hoan Hoang<p>You cannot change CPU frequency but you can however disable the HF and use LF clock source to save power.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/94367?ContentTypeID=1Tue, 01 Aug 2017 11:08:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bab450f7-1ff8-4fe7-97d4-8cf821c1cbe2endnode<p>No, all nRF5x chips have fixed clock architecture for MCU as well as all HW peripheral blocks. The only way how to save power is to manage each HW peripheral separately (= disable them when not used) and by using POWER ON SLEEP (wait for event) whenever possible (or go to POWER OFF if your application architecture allows it).</p> <p>If your HF clock source (external 32MHz crystal) will get out of spec then nRF5x chip can behave unpredictably (typically hardfault).</p><div style="clear:both;"></div>
