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 DS1245W PCM

device to be surface mounted without subjecting its lithium backup battery to destructive high-

temperature reflow soldering. After a DS1245W module base is reflow soldered, a DS9034PC PowerCap

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

prevent improper attachment. DS1245W module bases and DS9034PC PowerCaps are ordered separately

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