* 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/VPP 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.
