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 indicat-

ed in the Operating sections of this specification is

not implied. Exposure to Absolute Maximum Rat-

ing conditions for extended periods may affect de-

vice reliability. Refer also to the

STMicroelectronics SURE Program and other rel-

evant quality documents.

Note: 1. Soldering temperature not to exceed 260°C for 10 seconds (total thermal budget not to exceed 150°C for longer than 30 seconds).

No preheat above 150°C, or direct exposure to IR reflow (or IR preheat) allowed, to avoid damaging the Lithium battery.

CAUTION! Negative undershoots below -0.3V are not allowed on any pin while in the Battery Back-up Mode.
