*These parameters are characterized but not tested.

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 EC oscillator mode, the OSC1/CLKIN pin is a Schmitt Trigger input.

The leakage current on the MCLR/VPP 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.

Negative current is defined as current sourced by the pin.

Parameters are per USB Specification 1.1. No Microchip specific parameter numbers exist (per the PICmicro Mid-Range

Reference Manual, DS33023.
