These parameters are characterized but not tested.

Data in âTypâ column is at 3.0V, 25Â°C unless otherwise stated. These parameters are for design guidance only and are

not tested.

In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended to use an external

clock in RC mode.

Negative current is defined as current sourced by the pin.

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.

Including OSC2 in CLKOUT mode.
