† 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 EXTRC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the
PIC12C5XX 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 coming out of the pin.
4: This spec. applies when GP3/MCLR
is configured as MCLR. The leakage current of the MCLR circuit is higher than the
standard I/O logic.
