Hello all, I selected ARM as the toolchain but I guess this is a general question actually. Every device that I saw so far clearly specifies the allowed temperature operational range. But what happens in terms of electrical properties if you, say, exceed that by heating the device (stopping short of melting the device)?
The STR9 has a low voltage detection circuit: if the temperature causes the circuit to drop voltage, maybe I can save some data in an EEPROM before it's all over. The reference manual warns only of "permanent damage to the device".
1) why are you concerned with this? 2) maybe I can save some data in an EEPROM will that not get hot too? 3) there are military and industrial temperature rangs available for many chips

Mil-spec is -55 .. +125C Industry is -40 .. +80C Also look at automotive -40 .. +125C
Erik, No, I am not in the weapons industry. My conscious would not allow that. I am curious because somebody asked me, and I didn't really know what to say. And then I asked myself: "what would I have done in such a situation?". control units of the kind that I work with are not expected to be exposed to more than, say, 50 degree celsius.
And then I asked myself: "what would I have done in such a situation?".
It's really quite simple: Don't be in such a situation!
A device can either withstand a given temperature, or it can't. If didn't, it's dead. Forever. Case closed.
