There have been a few threads over time about higher temperature uC.

This news from Infineon on their XC866-HOT family is relevent - they
claim to have 140'C operate, full spec, and 100K flash operations at
140'C - price of e1.80/10K also is not 'niche' pricing, and
could target system watchdog applications in the tough installations.

I didn't read the link, but 140 C is good. I've had an MSP430 running
well at about the same temperature -- just to see -- but I didn't ding
around seeing how well the flash would survive. I figured that may be
a serious problem, especially if trying to erase and program at that
temperature. There are times when running CPUs at higher temps is
desirable.
