† 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 PIC12F508/509/
16F505 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: The specification applies to all weak pull-up devices, including the weak pull-up on GP3/MCLR
. The current listed will be the same
whether GP3/MCLR
is configured as GP3 with a weak pull-up or enabled as MCLR.
5: This specification applies when GP3/RB3/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.
