What the guys that I've worked with in the past have told me is that=20 you want to use the "C" versions of the PIC chips rather than the "F"=20 versions. But I don't have personal experience with this myself and=20 am just repeating what amounts to hearsay. That said: these guys have used tens of thousands of PICs over the=20 years at temperatures that exceed 200C. All "C" versions, of course. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
