† 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: Does not include GP3. For GP3 see parameters D0061 and D0061A.
5: This specification applies to GP3/MCLR
configured as external MCLR and GP3/MCLR configured as input with internal pull-up
enabled.
6: This specification applies when GP3/MCLR
is configured as an input with pull-up disabled. The leakage current of the
MCLR
circuit is higher than the standard I/O logic.
