FMAX
In 8-Bit External Memory mode:
FMAX = (9.55 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz, if VDDAPPMIN ≤ 4.2V;
FMAX = 25 MHz, if VDDAPPMIN > 4.2V.
In all other modes:
FMAX = (16.36 MHz/V) (VDDAPPMIN – 2.0V) + 4 MHz;
FMAX = 40 MHz, if VDDAPPMIN > 4.2V.
Note: VDDAPPMIN is the minimum voltage of the PIC^® device in the application.
