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: Extended operating range is Advanced Information for this device.

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.

7: Does not include GP3. For GP3 see parameters D0061 and D0061A.
