nRF52840 GPIO drive capability

[victor zheng]

Hi Team

The max value of IOH and IOL is the total current of all GPIO, or It is the value for each of GPIO pin？

I have read the post https://devzone.nordicsemi.com/f/nordic-q-a/12614/max-gpio-current-for-nrf52

I just want to double confirm that the total output current or input current of all GPIO can't exceed 15mA no matter it was configured as S0S1 or H0H1 in nRF52840?

Regards

Victor

Hi Victor,

The max GPIO sink/source current is 15 mA. This is max both from one pin or as the total for all the pins (entire package).
