RE: nRF52840 VIH MAX voltage is VDD

Hello,

[quote user=""]Does the definition VIH max=VDD is correct or a mistake? On other MCUs usually the VIH max=VDD+0.5V so the margin is 0.5V above the VDD of the nRF52840[/quote]

Yes, I think the product specification is correct. Apart from the specification you pointed out, there is an absolute maximum rating section(Page No: 623, PS) that shows the maximum rating you can apply, or, I would say, the maximum ratings we have tested. So we recommend smooth working inside this bracket, and values outside have not been tested here.

Kind Regards,
