https://devzone.nordicsemi.com/f/nordic-q-a/79105/nrf53-low-frequency-i-o-only-pinsOn the nRF52840 there were many pins specified as &quot;low frequency I/O only.&quot; Does the nRF53 have this same restriction? I don&#39;t see mention of these pins in the nRF53 datasheet.

But the result is probably the same as for the nRF52 series, all pins on the right hand side (same side as the radio) of the aQFN will be affected (see picture below). The same pins will apply for the CSP package as well. The product specification will be updated with this information when testing is completed.</span></p> <p><span>&nbsp;</span><img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/pastedimage1608212668248v1.png" alt=" " /></p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
