STM32F777 SPI Ports VIH Levels

[Chiku]

Hi,

I am using STM32F777, can you please help where i will get VIH voltage level for SPI Ports in datasheet?

Please help

Hi AScha,

Thank You.

For better understanding, I have attached Snapshot form STM32F777 Datasheet.

Also please confirm it is applicable for SPI Channel as well.

In my Case, I have VDD:3.3V

So VIH=(0.45*VDD+0.3)/(0.7*VDD)=(0.45*3.3+0.3)/(0.7*3.3)=0.77V

is it right? Please confirm

nooo....no division !

tested is : 0,7 * Vdd -> 2,31 V min.

here you see : tested 2,3V ; may switch from 1,7V up (green line).

and SPI is same other port pins , ok?
