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.

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

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

IIO

Output current sunk by any I/O and control pin

ΣI(PIN)

Total output current sunk by sum of all I/Os and control pins(2)

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.

IINJ(PIN)(3)(4)

3. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the

specified maximum value.

4. A positive injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. IINJ(PIN) must

never be exceeded. Refer also to Table 10: Voltage characteristics for the maximum allowed input voltage

values.
