11.0 DC AND AC CHARACTERISTICS - PIC16HV540
The graphs and tables provided in this section are for design guidance and are not tested or guaranteed. In some graphs
or tables the data presented are outside specified operating range (e.g., outside specified V
DD range). This is for infor-
mation only and devices will operate properly only within the specified range.
The data presented in this section is a statistical summary of data collected on units from different lots over a period of
time. “Ty pi ca l” represents the mean of the distribution while “max” or “min” represents (mean + 3σ) and (mean – 3σ)
respectively, where σ is standard deviation.

Note 1: This combination of R, C and VDD draws too
much current and prohibits oscillator operation.
