 Having gone through the nRF52832 datasheet, the only discernible drawbacks of moving from an external crystal to synthesizing the Low frequency clock from the high-frequency clock appears to be:

So the total will be 100uA +&amp;nbsp;&lt;span&gt;250uA = 350 uA.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
