U.L. recognition and recycling

While providing innovative, leading edge products, STMicroelectronics remains committed

to safety, including its products, its customers, and the environment. Each device contains

reverse-charge protection circuitry, and uses safe lithium mono-fluoride batteries. All

ZEROPOWER®, TIMEKEEPER, supervisor, and serial RTC components are recognized by

Underwriter’s Laboratory under file number E89556, and are compliant to the LL-94-VO

flammability rating.

The unique SNAPHAT packaging consists of a 330 mil SOIC device and a separate, “snap-

on” SNAPHAT, which includes both the lithium power cell, and in the case of TIMEKEEPER

product, a high accuracy crystal. The SNAPHAT is removable and can be replaced,

providing the added benefit of proper disposal or recycling that has not been available

before with NVRAMs. Various companies offer recycling and safe disposal of scrap lithium

cells.
