Any PIC made will operate from 0 to 100mHz. ;-) If you want to see the kind of subtle faults that can affect micros at the margins of speed and temperature (and unit variations) see the errata for the 18F series. Instructions that work on SOME operands, SOME of the time, at SOME temperatures. 8-( If you want to invite that sort of monster to come live with you, you're more than welcome to it. OTOH, I *could* make a case for stretching the specs by a small percentage if it can be inferred that, due to say restricted temperature range, the parts will all work, guaranteed by the laws of physics and the testing done at Microchip.
