† 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 nor-
mal 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 spec. applies to GP3/MCLR
configured as external MCLR and GP3/MCLR configured as input with internal pull-up enabled.
6: This spec. 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.
