For PIC18F6520/8520 in Microcontroller mode:
4 MHz
4.2V
FMAX = (16.36 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN  4.2V;
F
MAX = 40 MHz, if VDDAPPMIN > 4.2V.
For PIC18F8X8X in modes other than Microcontroller mode:
F
MAX = (9.55 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN  4.2V;
F
MAX = 25 MHz, if VDDAPPMIN > 4.2V.
Note: V
DDAPPMIN is the minimum voltage of the PIC
