STM32F030C8T6 internal protection of port PB8 and PB9 (FTf ports): Is voltage -0.35V with 100k series resistor a problem for the STM32?

We use the schematic attached to convert a 230 VAC signal to the STM32 level (low cost product). Maximum input high level is about 3.9 V. In worst case 5.4 V. This should not be a problem for the FTf pin because specification is VDDIO+4V = 7.3 V.But ...

I had a problem with STMF334R8, I loaded the same program on several boards with some STLINK V-2, via CubeIDE and then I was unable to get them to connect again to the computer to load another program with any kind of st link. What could cause that?

I had a problem with STMF334R8, I loaded the same program on several boards with some STLINK V-2, via CubeIDE and then when I tried to conect the MCU's again to the computer i had an error: failed to initialize GDB server, and in the console it appea...

STM32F412CGU6 ESD Issues

Hi, We have a product based on a STM32F412CGU6 MCU that is currently going through certification. Are there any known ESD issues or knwn reasons why the MCU would tend to latch up? We are seeing this behaviour and can't get to the bottom of it.Thanks...
