Have I missed something? > I was told this by a MChip FAE at a MChip seminar (after using the JW device at high temp for a couple of years). My first thought was that he hadn't recovered from the sixties. I guess what the specs all come down to is butt-covering - but to be fair, maybe what he meant was that the screening procedures are different for JWs. What he did do, however, was to challenge me to find _anywhere_ in the data book that said the JW was spec'ed to 125. He said that you have to go to an E-suffix part for that. Microchip, can you clarify this? Brian Boles...I know you're watching. --Matt
