Electrical characteristics
6.2
Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 12: Voltage characteristics,
Table 13: Current characteristics, and Table 14: 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 13: Current characteristics for the maximum
allowed injected current values.
