https://devzone.nordicsemi.com/f/nordic-q-a/21027/io-capacitance-on-nrf52Are there any specs on the rough I/O capacitance of the nRF52? Doing some circuit trickery where a few pF can be important to compensate for.en-USTelligent Community 13Sun, 02 Apr 2017 22:08:12 GMThttps://devzone.nordicsemi.com/thread/82154?ContentTypeID=1Sun, 02 Apr 2017 22:08:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:72153454-2904-4cd0-813c-b00f164cbb05samsonc<p>Thank you! I had someone completely missed that spec line.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/82153?ContentTypeID=1Sun, 02 Apr 2017 19:57:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7a598b73-2e68-4209-9e5f-c0dc3e88b6baH&#229;kon Alseth<p>It&#39;s 3 pF, unless you use the NFC pins as GPIOs, in which it&#39;s 4 pF. See Cpad and Cpad_nfc in the specs: <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/gpio.html?cp=2_2_0_19_3_0#unique_122699147">infocenter.nordicsemi.com/.../gpio.html</a></p> <p>Cheers, Håkon</p><div style="clear:both;"></div>
