https://devzone.nordicsemi.com/f/nordic-q-a/125534/which-gpio-domain-for-lpcompHello, we would like to use the LPCOMP on the nRF54LM20A, but there&#39;s some confusion on which GPIO domain can be used. According to the overview block diagram , LPCOMP lies in the LP PD with GPIO P0. However, the documentation for the LPCOMP refersen-USTelligent Community 13Tue, 11 Nov 2025 13:40:34 GMThttps://devzone.nordicsemi.com/thread/553984?ContentTypeID=1Tue, 11 Nov 2025 13:40:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:68ac5c1a-44cb-4cd0-a69b-83a5534be964SwRa<p>HI Leon,</p> <p>This is not a mistake.. The LPCOP peripheral itself lies in the Low power domain.. However, all analog input pins for LPCOMP (AIN0–AIN7)&nbsp;are located on&nbsp;GPIO port P1, which belongs to the&nbsp;Peripheral (PERI) power domain. See here:&nbsp;<a href="https://academy.nordicsemi.com/courses/nrf54l-series-express-course/lessons/lesson-2-power-domains-event-system-and-gpio/topic/gpio-ports-and-pin-planning/#Essential-pin-planning-rules">https://academy.nordicsemi.com/courses/nrf54l-series-express-course/lessons/lesson-2-power-domains-event-system-and-gpio/topic/gpio-ports-and-pin-planning/#Essential-pin-planning-rules</a>&nbsp;</p> <p>Both the LP domain and PERI domains must be powered for LPCP operation.</p> <p>Regards,</p> <p>Swathy</p><div style="clear:both;"></div>
