The DS1245 devices are 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 memory and nonvolatile control along with contacts for connection to the lithium battery in the DS9034PC PowerCap. The PowerCap Module package design allows a DS1245 PCM device to be surface mounted without subjecting its lithium backup battery to destructive high-temperature reflow soldering. After a DS1245 PCM is reflow soldered, a DS9034PC PowerCap is snapped on top of the PCM to form a complete Nonvolatile SRAM module. The DS9034PC is keyed to prevent improper attachment. DS1245 PowerCap Modules and DS9034PC PowerCaps are ordered separately and shipped in separate containers. See the DS9034PC data sheet for further information.
