1. FT = 5V tolerant. To sustain a voltage higher than V
2. 0.7V
3. FT = Five-volt tolerant.
4. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization, not tested in production.
5. With a minimum of 200 mV. Based on characterization, not tested in production.
6. The max. value may be exceeded if negative current is injected on adjacent pins.
7. Pull-up and pull-down resistors are designed with a true resistance in series with a switchable PMOS/NMOS. This

Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to ±8 mA, and sink or
source up to ±20 mA with the non-standard V
in the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in
