Frequency
Equation 1: FMAX = (6.0 MHz/V) (VDDAPPMIN â 2.0V) + 4 MHz; VDDAPPMIN = 2.0V - 3.0V
Equation 2: FMAX = (10.0 MHz/V) (VDDAPPMIN â 3.0V) + 10 MHz; VDDAPPMIN = 3.0V - 4.0V
Note 1: VDDAPPMIN is the minimum voltage of the PIC® device in the application.
Note 2: FMAX has a maximum frequency of 10 MHz.
