Hi!
Does anyone know what the temperature range is for Atmel's STK kits? I've installed Industrial temp range micros on the STK200 and 300 boards that I'm using. I didn't find any spec for this in the manuals for the boards. I'll try to email Kanda about it but I'd appreciate any information you can share.

Thanks, Scott Pierskalla

Hello,
The real trick, of course, is to determine the component on the STK-200 that has the lowest maximum operating temperature rating. FR-4 is rated up to about 130 degrees C or so, so the board itself is not the limiting factor. Generally speaking, most standard IC's are rated for 85 degrees C. Just looking at my board, it looks like some of the electrolytic capacitors are also rated up to 85 degrees C.
For many of the parts, you can look up the temperature ratings on the data sheets. However, since it would be pretty hard to find the exact part numbers and manufacturers for every part on the board, you may have to end up making an educated guess. If I were to do so, I would say that it should be rated up to 85 degrees C. However, if this would be part of a safety-critical system, then making educated guesses is not good enough -- you'd better find out for sure!

Regards,
Philip Bright

The brownout detector voltage threshold is temperature dependent.
The regulator may need a heatsink st higher ambient temperatures.
