Can anyone offer their personal experiences when dealing with PIC=20 microcontrollers in high-temperature applications -- say, > 170C...=20 Outside of the stated ranges. Specifically, is there a particular device that works for you? Do you=20 consider thermal resistance in your design? Heat-sinking? PCB?
