∑|IINJ(PIN)|

Total injected current (sum of all I/Os and control pins)(5)

1. All main power (VDD, VDDRF, VDDA, VBAT) and ground (VSS) pins must always be connected to the external power

supply, 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 referring to high pin count packages.

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 to Table 16 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).
