* These parameters are characterized but not tested.
† Data in ‘Typ’ column is at 5.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
Note 1: In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended to use an external
clock in RC mode.
2: Negative current is defined as current sourced by the pin.
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.
4: See Section 14.4.1 “Using the Data EEPROM” on page 105.
