Many ST documents says that FT pins are 5V tolerant only in (Digital) Input mode. They are not 5V tolerant when configured in Analog mode and analog peripheral like ADC or OPAMP is connected to it. But are they 5V (or more precisely Vdda + 3.6V toler...

Hi @STOne-32 . Thank you for answer.VDD=0V should be ok becase when MCU is not powered, voltage on input will not exceed 2.25V in my case. According to AN4899 this should be safe also:

I did typo when writing my qeustion.Following sentense:"When ADC will not be in progress, both FT GPIO1 and 2 will be in Analog mode (High impedance with Schmidt trigger disabled) and ADC will be disconnected from ADC (channel will be disabled)."Shou...

Hi @STOne-32 ! Thank you for reply.My question is: If the FT pin will accept input voltage higher than Vdda (and Vdd which is at the same level as Vdda) when configured in Analog Mode (GPIOx_MODER=0b11), internall pull-up and pull-down are disabled ...
