Maximum ratings
Stressing the device above the rating listed in the absolute maximum ratings table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
Table 10.
1. For SO16 and SOH28 package, lead-free (Pb-free) lead finish: reflow at peak temperature of 260°C (the
Negative undershoots below –0.3 V are not allowed on any pin while in the battery backup
mode.
