DS1330Y/AB

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 DS1330 PCM device to be surface mounted without subjecting its lithium backup battery to

destructive high-temperature reflow soldering. After a DS1330 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. DS1330 PowerCap modules and DS9034PC PowerCaps are ordered separately and

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