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 the 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 input source voltage and device pin. The resistor value is calculated according to:
    • 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.
  6. IOL/IOH is specific to AC operation. For continuous DC operation characteristics, refer to the Absolute Maximum Ratings section.
  7. Not all I2C operating modes are supported on all pin types. Refer to the Table I2C Support below.
