STM32F103 work temperation at -55C

kent gu · ‎2023-02-22

Hi,

Now we want to use STM32F103 at -55C ambient temperature, MCU

data sheet say that it work at -40C as datasheet, storage temperature is -60C.

My question is that,

-If MCU is powered up at -55C, what will be different with

>=-40C? Such as clock not stable,

-Do you have any -55C mcu as STM32F103 function for

recommendation?

Best Regards,

Kent

So far, no derivative of the STM32 is guaranteed to operate at a temperature lower than -40C. A statement about the behaviour at lower temperatures than the minimum operating temperature (most have -40C, a few -20C or -10C) can therefore not be made and one must assume that in extreme cases the STM32s will not work at all.

If the problem is solved, please mark this thread as answered by selecting Select as best, as also explained here. This will help other users find that answer faster.
