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 V
IH specification is only in relation to externally applied inputs and not with respect to the user-select-
able pull-ups. Externally applied high impedance or open drain input signals utilizing the PIC32 internal pull-
ups are guaranteed to be recognized as a logic “high” internally to the PIC32 device, provided that the
external load does not exceed the maximum value of I
CNPU.
7: VIL source < (VSS - 0.3). Characterized but not tested.
8: V
IH source > (VDD + 0.3) for non-5V tolerant pins only.
9: Digital 5V tolerant pins do not have an internal high side diode to V
DD, and therefore, cannot tolerate any
“positive” input injection current.
10: Injection currents > | 0 | can affect the ADC results by approximately 4 to 6 counts (i.e., V
IH Source > (VDD +
0.3) or VIL source < (VSS - 0.3)).
11: Any number and/or combination of I/O pins not excluded under I
ICL or IICH conditions are permitted pro-
vided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the speci-
fied limit. If Note 7, IICL = (((Vss - 0.3) - VIL source) / Rs). If Note 8, IICH = ((IICH source - (VDD + 0.3)) / RS).
RS = Resistance between input source voltage and device pin. If (V
SS - 0.3)  VSOURCE  (VDD + 0.3), injec-
tion current = 0.
