Electrical characteristics STM32L031x4/6
50/126 DS10668 Rev 6
6.2 Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 17: Voltage characteristics,
Table 18: Current characteristics, and Table 19: 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. Device mission profile (application conditions)
is compliant with JEDEC JESD47 Qualification Standard. Extended mission profiles are
available on demand.
