DS1330W

FRESHNESS SEAL

Each DS1330W is shipped from Dallas Semiconductor with its lithium energy source disconnected,

guaranteeing full energy capacity. When VCC is first applied at a level greater than VTP, the lithium

energy source is enabled for battery backup operation.

PACKAGES

The 34-pin PowerCap Module integrates SRAM memory and nonvolatile control into a module base

along with contacts for connection to the lithium battery in the DS9034PC PowerCap. The PowerCap

Module package design allows a DS1330W device to be surface mounted without subjecting its lithium

backup battery to destructive high-temperature reflow soldering. After a DS1330W module base is reflow

soldered, a DS9034PC is snapped on top of the base to form a complete Nonvolatile SRAM module. The

DS9034PC is keyed to prevent improper attachment. DS1330W module bases and DS9034PC

PowerCaps are ordered separately and shipped in separate containers. See the DS9034PC data sheet for

further information.
