Note:
  1. VIL source < (GND - 0.3). Characterized but not tested.
  2. VIH source > (VDDIO + 0.3) for non-5V tolerant pins only.
  3. Digital 5V tolerant pins do not have an internal high side Diode-to-VDDIO, and therefore, cannot tolerate any “positive” input injection current.
  4. If the sum of all injection currents are > | ∑IICT | it can affect the ADC results by approximately 4 to 6 counts (i.e., VIH Source > (VDDIO + 0.3) or VIL source < (GND - 0.3)).
  5. Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the specified ∑IICT limit. To limit the injection current the user must insert a resistor in series RSERIES, (i.e. RS), between the input source voltage and device pin. The resistor value is calculated according to the following:
    • For negative Input voltages less than (GND-0.3): RS ≥ absolute value of | ((VIL source - (GND - 0.3)) / IICL) |
    • For positive input voltages greater than (VDDIO +0.3): RS ≥ ((VIH source - (VDDIO +0.3))/ IICH)
    • For Vpin voltages >VDDIO +0.3 and <GND-0.3 then RS = the larger of the values calculated above
