Note 1: Data in “Typ” column is based on characterization results at 25
°C. These parameters are for design guidance
only and are not tested for, or guaranteed by Microchip Technology.
Note 2: Total power dissipation as stated under absolute maximum ratings must not be exceeded.
Note 3: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified levels
represent normal operating conditions. Higher leakage current may be measured at different input voltages.
Note 4: Negative current is defined as coming out of the pin.
Note 5: In RC oscillator mode, the OSC1 pin is a Schmitt trigger input. It is not recommended that the microcontroller
be driven with external clock in RC mode.
Note 6: The user may use better of the two specifications.
