For more critical uses, Infineon seem to have well-spec'd uC -
their new ones all have Error Correcting Flash, and 125'C models.

Also recently added are a series of Transmitter ICs for Wireless 
Control, that have Sub 1GHz Transmitters, and Low power Flash C51's
- one targets Tire Pressure, at Automotive temp range.

Flash retention is one of those 'fingers crossed' specs from most
suppliers. They cannot TEST years of use, so they do a little 
extrapolation, and we all know, extrapolation is dangerous :)
