1. All main power (VDD, VDDA) and ground (VSS, VSSA) 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 LQFP packages.

3. Positive current injection is not possible on these I/Os. A negative injection is induced by VIN < VSS. IINJ(PIN) must never be

exceeded. Refer to Table 12 for maximum allowed input voltage values.

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 to Table 12 for the maximum allowed input voltage values.

5. When several inputs are submitted to a current injection, the maximum ΣIINJ(PIN) is the absolute sum of the positive and

negative injected currents (instantaneous values).
