Dear Sir's,
what is the minimum high level threshold voltage
for a non FT_C port? Is it 0.7xVDD or 0.49xVDD+0.26?
Regards,
Jochen

Hello @JR1 and welcome to the community 🙂,
These 2 formulas are correct VIH = 0.7x VDD is the threshold tested in production and VIH=0.49xVDD+0.3V is the threshold guaranteed by design as mentioned in note 3.
This behavior is mentioned in data sheet figure 25: in blue the threshold level tested in production and in green the threshold level guaranteed by design.
May this discussion can help you.

What does the note (3) tell you?
