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.
