Dear all,
i want to use the automotive atmega88/168.
The data sheet is availale under:
It is for 150 Degree Operating Tempratuer
Now..............
Can i use Arduino to make my prgramm for it?
In the Kit ( Duemilanove) is the atmega168 availabe, but it is for 85 Degree Only as a DIP package!!!!!!!!
Does any body know, which arduino compatible board is available for high temprature?
Can i use the Nano with Atmega328 for high temprature Application?
Does the family atmega328 support high temprature operation?
I would be glad if sombody could help me in my case.
Why do you want to operate it at such high temperatures? It is not only the processor that has to survive this. The regulator, the crystal, the caps, everything would have to deal with this temperature.
I'd like to see the solder withstand those temperatures for a large amount of time...
Why is it necessary to go up to those temperatures? You know, water boils at 100, right? Are you planning to put the Arduino inside a combustion chamber or something?
Dear all,
i need the 150 degree in research application.
I will take care about solder and other components for 150 degree Celisius.
Please, and please: My Question:
Can i use Arduino for the Atemage168 Automotive?
Thanke you

Well my opinion is no, not if you are actually going to subject the board to 150C operation. Subjecting most electronic components to 150C/330 F far exceeds their maximum ratings so you would have to research every single component on a arduino board (including the board material and the IC socket and other connectors) to see if they can operate at that temp and if not try and find suitably rated components.
You are dealing with a very limited application requirement. I recall special Motorola ICs that were designed to be used in deep water oil well drilling applications that were rated at around 350F max temp range but the costs were extreamly high and I'm sure the other support components needed were very difficult to source.
Its is the same part, but characterised for high-temperature as far as I can see. Note the lower per-pin maximum current spec though. Shouldn't be any problem programming it on an Arduino unless it has different signature bytes.
Other posters seem to think you intend to run the Arduino board hot, but I don't believe you meant that.
Actually, I think that what he meant was to use the Atmega168, with the bootloader and maybe some Arduino written code on a different board than Arduino made for this research.
One thing I'd like to point out here is that, when a datasheet states Absolute Maximum Ratings it is not to be used at a steady state. Will the ATmega chip work on 150 degrees? I think so. But, will it work for long? No, it won't. Plus, are you really trying to go up to 150 degrees or within 150 without actually getting there?

Indeed - one of the graphs in that datasheet shows the reduced expected lifetime at higher temperatures - which drops orders of magnitude in fact... Prob. OK for research of course.
Until they come out with a SiC version of the chip I doubt you can run hotter!
