Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 7: Voltage characteristics,
Table 8: Current characteristics, and Table 9: 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. VIN maximum must always be respected. Refer to Table 8: Current characteristics for the maximum
allowed injected current values.

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. Negative injection disturbs the analog performance of the device. See note 3 below Table 65 on page 103.
3. Positive 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 7: Voltage characteristics for the 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 7: Voltage characteristics 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).
