DS1330W
FRESHNESS SEAL
Each DS1330W is shipped from Dallas Semiconductor with its lithium energy source disconnected,
guaranteeing full energy capacity. When V
is first applied at a level greater than V
, the lithium
CC
TP
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.
