I/O port pin characteristics
General Characteristics
Subject to general operating conditions for V33 and TA unless otherwise specified. All
unused pins must be kept at a fixed voltage: using the output mode of the I/O for example or
an external pull-up or pull-down resistor.
Notes:
1.
Data based on characterization results, not tested in production.
2.
Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
3.
When the current limitation is not possible, the VIN absolute maximum rating must be respected, otherwise
refer to IINJ(PIN) specification. A positive injection is induced by VIN>V33 while a negative injection is
induced by VIN<VSS. Refer to Section 2.2 on page 33 for more details.
4.
Leakage could be higher than max. if negative current is injected on adjacent pins.
5.
The RPU pull-up and RPD pull-down equivalent resistor are based on a resistive transistor (corresponding
IPU and IPD current characteristics described in Figure 18 to Figure 19).
