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.
In ER oscillator configuration, the OSC1 pin is a Schmitt Trigger input. It is not recommended that the PIC16F62X be driven with exter-
nal clock in ER mode.
The leakage current on the MCLR pin is strongly dependent on applied voltage level. The specified levels represent normal operating
conditions. Higher leakage current may be measured at different input voltages.
Negative current is defined as coming out of the pin.
