Probably OK for one-offs but you can never be sure (without testing) whether all functions of the chip (as guaranteed by Microchip) will work properly when anything is out of spec There had been reports of 10MHz F84s being chugged along at almost 70MHz, but I don't know if they are still chugging -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
