Maximum rating

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.

Caution:

Negative undershoots below –0.3V are not allowed on any pin while in the battery back-up

mode.

For SOX18 package, Lead-free (Pb-free) lead finish: Reflow at peak temperature of 240°C (total thermal

budget not to exceed 180°C for between 90 to 150 seconds). No direct exposure to infrared (IR) reflow, or

IR preheat allowed, to avoid damaging the embedded 32KHz crystal.
