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. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum
cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive
injection is induced by VIN > VDD while a negative injection is induced by VIN < VSS
.
3. Negative injection disturbs the analog performance of the device. See note in Section 5.3.17: 12-bit ADC
characteristics.
4. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the
positive and negative injected currents (instantaneous values). These results are based on
characterization with IINJ(PIN) maximum current injection on four I/O port pins of the device.
