†

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 PIC12C67X

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 D061 and D061A.

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.
