https://devzone.nordicsemi.com/f/nordic-q-a/85006/nrf5340-low-drive-low-frequency-pin-clarificationHi, We are Migrating from nRF52832 to nRF5340 dual-core soc. In nRF52832 9 off available GPIOs were only to use with a low drive, low-frequency application since they may affect the radio performance. The nRF5340 is a dual-core SoC and GPIO pins ofen-USTelligent Community 13Tue, 22 Feb 2022 14:52:15 GMThttps://devzone.nordicsemi.com/thread/354396?ContentTypeID=1Tue, 22 Feb 2022 14:52:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:80b5dc4e-6707-4ae0-82a1-dfa1cdd5fd40Simonr<p>Hi</p> <p>No, there aren&#39;t any nRF5340 GPIOs specifically noted as recommended to use as low drive, low-freq, but just a select few are able to run at Extra High drive as specified in the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf5340%2Fchapters%2Fpin.html">Pin assignments chapter.</a>&nbsp;There shouldn&#39;t be anyone that specifically can&#39;t be used for the &quot;regular&quot; high-frequency application, but to be on the safe side I would start by using the ones that are specifically mentioned as designed for extra high and high drive for the most demanding processes, as these are the furthest away from the radio. Only sticking to the app core pins should be fine.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
