IO capacitance on nRF52

[samsonc]

Are 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.

It's 3 pF, unless you use the NFC pins as GPIOs, in which it's 4 pF. See Cpad and Cpad_nfc in the specs: infocenter.nordicsemi.com/.../gpio.html

Cheers, Håkon

Thank you! I had someone completely missed that spec line.
