1. All main power (VDD, VDDSMPS, VDDA, VDDUSB, VDDIO2, VDDDSI, VBAT) and ground (VSS, VSSA, VSSSMPS) pins

must always be connected to the external power supply, in the permitted range.

2. The I/O structure options listed in this table can be a concatenation of options including the option explicitly listed.

For instance TT_a refers to any TT I/O with _a option. TT_xx refers to any TT I/O and FT_xx refers to any FT I/O.

3. VDDIO1 or VDDIO2, VDDIO1 = VDD.

4. VIN maximum must always be respected. Refer to Table 31 for the maximum allowed injected current values.

5. To sustain a voltage higher than 4 V, the internal pull-up/pull-down resistors must be disabled.

6. This formula has to be applied only on the power supplies related to the I/O structure described in the pin definition table.

7. Including VREF- pin.
