1. All power (VDD, VDDA, VDD3V3_USB, VDDCORE, VBAT) and ground (VSS, VSSA, VSSX) pins must always be

connected to the external/internal power supply, in the permitted range.

2. VIN maximum must always be respected. Refer to Table 51 for the maximum allowed injected current

values.

3. This formula has to be applied on power supplies related to the IO structure described by the pin definition

table.

4. To sustain a voltage higher than 3.9 V the internal pull-up/pull-down resistors must be disabled.

5. Voltage should be also below Min(VDD, VDD3V3_USBFS) + 3.9 V

2. This current consumption must be correctly distributed over all I/Os and control pins. The total output

current must not be sunk/sourced between two consecutive power supply pins.
