PACKAGES
The 34-pin PowerCap Module integrates SRAM memory and NV control along with contacts for
connection to the lithium battery in the DS9034PC PowerCap. The PowerCap module package design
allows a DS1345 PCM device to be surface mounted without subjecting its lithium backup battery to
destructive high-temperature reflow soldering. After a DS1345 PCM is reflow soldered, a DS9034PC is
snapped on top of the PCM to form a complete NV SRAM module. The DS9034PC is keyed to prevent
improper attachment. DS1345 PowerCap modules and DS9034PC PowerCaps are ordered separately and
shipped in separate containers. See the DS9034PC data sheet for further information.
