What is the effect of low temperatures on semiconductors
(OP)
I am considering a mass market measurement device which involves exposure of a semiconductor chip to outside temperatures, ranging from -30 degrees C. to +40 degress C.
The semiconductor would have to act as a microprocessor, having these needs:
1) Provide an accurate clock pulse with outside recalibration only once in six months.
2) Store up to 4 MB of data.
3) Dump data at a high rate whem demanded to a host sytem. (Say 4 MB in 3 seconds)
4)Be powered by a watch size battery power source or smaller if possible.
The device I am considering is for a high volume application, so the cost could be significant
What type of semiconductor provides the best stability for temperature ranges?
What about battery material, at what temperature does a tiny battery lose its oomph due to the nature of low ambient temperature on the chemical reaction taking place in the battery?
Thank you for whatever light you can shed on this idea.

I'm not sure of your definition of semiconductor.
When you state "The semiconductor would have to act as a microprocessor..." it sounds as though you are asking for a PROM of varying flavors. Is it a "One-Chip" solution you are looking for? If so, you may consider a PAL, PLA, or other fully programmable logic packages. Maybe a high-end PIC, but I doubt it.
The data xfer speed is realistic in normal applications, but with the limited power available in your application, I'm not too sure. How far away from the storage appliance location will the dataloggers be? Will they be wired or wireless?
Sounds like a neat project :)!
