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 name tables (Table 2 through Table 4) for the 5V-tolerant pins.
6: The V
IH 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 I
CNPU. For External “input” logic inputs that
require a pull-up source, to guarantee the minimum V
IH of those components, it is recommended to use an
external pull-up resistor rather than the internal pull-ups of the PIC32 device.
