PACKAGES

The 34-pin PowerCap Module integrates SRAM memory and nonvolatile control along with contacts for

connection to the lithium battery in the DS9034PC PowerCap. The PowerCap Module package design

allows a DS1350 PCM device to be surface mounted without subjecting its lithium backup battery to

destructive high-temperature reflow soldering. After a DS1350 PCM is reflow soldered, a DS9034PC is

snapped on top of the PCM to form a complete Nonvolatile SRAM module. The DS9034PC is keyed to

prevent improper attachment. DS1350 PowerCap Modules and DS9034PC PowerCaps are ordered

separately and shipped in separate containers. See the DS9034PC data sheet for further information.
