I/O pin capacitance

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

2. If VIH maximum is not respected, the injection current must be limited externally to IINJ(PIN) maximum.

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. RPU pull-up equivalent resistor based on a resistive transistor (corresponding IPU current characteristics described in

Figure 28).

6. Guaranteed by characterization results.
