1. All main power (VDD, VDDIO2, VDDUSB, VDDA, VDDRF, VDDRFPA, VDDANA, VDDSMPS) and ground (VSS, VSSA,

VSSRF, VSSSMPS) pins must always be connected to the external power supply, in the permitted range.

2. VIN maximum must always be respected. Refer to Table 27 for the maximum allowed injected current values.

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

4. This formula applies only to power supplies related to the I/O structure described by the pin definition table.

1. All main power (VDD, VDDIO2, VDDUSB, VDDA, VDDRF, VDDRFPA, VDDANA, VDDSMPS) and ground (VSS, VSSA,

VSSRF, VSSSMPS) pins must always be connected to the external power supplies, in the permitted range.

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.

3. Positive injection (when VIN > VDD) is not possible on these I/Os and does not occur for input voltages lower than the

specified maximum value.

4. A negative injection is induced by VIN < VSS. IINJ(PIN) must never be exceeded. Refer also to Table 26 for the maximum

allowed input voltage values.

5. When several inputs are submitted to a current injection, the maximum ∑|IINJ(PIN)| is the absolute sum of the negative

injected currents (instantaneous values).
