These parameters are characterized but not tested.

†

Data in “Typ” column is at 5.0V, 25

°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1:

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.

See Section 9.4.1 “Using the Data EEPROM” for additional information.
