Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only

and are not tested.

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 current sourced by the pin.

4: This parameter is characterized, but not tested in manufacturing.

5: See the “Pin Diagrams” section for the 5V-tolerant pins.

6: The VIH specifications are only in relation to externally applied inputs, and not with respect to the user-

selectable internal pull-ups. External open drain input signals utilizing the internal pull-ups of the PIC32

device are guaranteed to be recognized only as a logic “high” internally to the PIC32 device, provided that

the external load does not exceed the minimum value of ICNPU. For External “input” logic inputs that require

a pull-up source, to guarantee the minimum VIH of those components, it is recommended to use an

external pull-up resistor rather than the internal pull-ups of the PIC32 device.
