Hi George,

If you are running a PIC18F8720/8620/6720/6620 greater than 25 MHz, then you
are running it out of specification.
Just look at the PIC18F6620/6720/8620/8720 VOLTAGE-FREQUENCY GRAPH in the
erratas (DS80172A, DS80129G).

I think this issue caught a lot of people off guard. The current data sheet
for the PIC18F8720/8620/6720/6620 devices states Fosc max of 40 MHz, but the
Fosc max has been down-graded in the errata which states 25 MHz Fosc max.

You might want to contact Microchip sales to get more info on this issue.

Hope this helps.

Best regards,

Ken Pergola
