STM32 MCUs can operate in vacuum environment?

Hi,

I would like to know if MCUs of ST can operate in a vacuum environment.

Thanks​

Check datasheet in case it has some info. I would guess it should work as there is no gas in chip and package. In case if radiations, it is another story.

Apart from the datasheet - as @S.Ma​ mentioned - try searching to see if there are any specs for the packaging?

Hi, not sure that you can find something in datasheet about using stm32 in a low pressure condition...

What about solder and chip can deliver in low pressure ambiant.

But you also must consider how heat can be conducted away...​
