These parameters are characterized but not tested.
Data in "Typ" column is at 5V, 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 that the
PIC16F87X be driven with external clock in RC mode.
2:
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.
3:
Negative current is defined as current sourced by the pin.
