... PACKAGES The DS1250W is available in two packages: 32-pin DIP and 34-pin PowerCap Module (PCM). The 32- pin DIP integrates a lithium battery, an SRAM memory and a nonvolatile control function into a single package with a JEDEC-standard 600-mil DIP pinout. The 34-pin PowerCap Module integrates SRAM for an out-of-tolerance condition ...

... DS9034PC PowerCap. The PowerCap Module package design allows a DS1250W PCM device to be surface mounted without subjecting its lithium backup battery to destructive high- temperature reflow soldering. After a DS1250W module base is reflow soldered, a DS9034PC PowerCap is snapped on top of the base to form a complete Nonvolatile SRAM module ...
