Hello, i have some questions about current injection onSTM32G431CBT3 pins.On datasheet Table 15 it is reported:IINJ(PIN) -> Injected current on FT_***, TT_xx, NRST pins ->-5/0NOTE3:Positive injection (when VIN > VDD) is not possible on these I/Os and...

Hi STALA_1about your first questionthe 3V3 for Vdd and Vdda is obtained from a BUCK/Step-down DCDC converter 12V (in) ->3.3V (out)The P/N is not relevant.The analog input is on a TT_a pin.That's why i'm asking for it,But, how can you imagine, during ...

Hello STALA1 and thanks,In the AN4899 it is reported "0 mA means that current injection can damage the GPIO and induce STM32 malfunction.""Warning: positive current injection is prohibited for a TT or FT GPIOdefined as 0 mA"While in your explaination...
