I/O pin capacitance

1. VDD = 3.0 V, TA = -40 to 125 °C unless otherwise specified.

2. Data based on characterization results.

3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.

4. The max. value may be exceeded if negative current is injected on adjacent pins.

5. Not tested in production.
