Threshold for low at GPIO Input

[Dominik Eugster]

What is the threshold voltage on a nRF52840 GPIO to detect low level powered with 3.3V?

Can't find it in the datasheet. High level threshold will be 0.7*VDD right? 0.7 * 3.3V = 2.31V

Hi,

 

What is the threshold voltage on a nRF52840 GPIO to detect low level powered with 3.3V?

less than or equal to 0.3*VDD (<= 0.99V for 3.3V VDD):
