FMAX
For PIC18F6520/8520 in Microcontroller mode:
FMAX = (16.36 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN ≤ 4.2V;
FMAX = 40 MHz, if VDDAPPMIN > 4.2V.
For PIC18F8X8X in modes other than Microcontroller mode:
FMAX = (9.55 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN ≤ 4.2V;
FMAX = 25 MHz, if VDDAPPMIN > 4.2V.
Note: VDDAPPMIN is the minimum voltage of the Picmicro^® device in the application.
