PACKAGES

The DS1250 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

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 DS1250 PCM

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

temperature reflow soldering. After a DS1250 PCM module base 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. DS1250 module bases and DS9034PC PowerCaps are ordered

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