* These parameters are characterized but not tested.
Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25
°
C. This data is for design guid-
ance only and is not tested.
2: The leakage current on the MCLR/V
PP
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
voltage.
3: Negative current is defined as coming out of the pin.
4: For PIC12C5XX devices, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC12C5XX be driven with external clock in RC mode.
5: The user may use the better of the two specifications.
