Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 6: Voltage characteristics,
Table 7: Current characteristics, and Table 8: Thermal characteristics may cause permanent
damage to the device. These are stress ratings only and functional operation of the device
at these conditions is not implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.

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 (see Table 7: Current characteristics). 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> VINmax while a negative injection is
induced by VIN < VSS
