PACKAGES
The DS1230W is available in two packages: 28-pin DIP and 34-pin PowerCap Module (PCM). The 28-
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 DS1230W to be
surface mounted without subjecting its lithium backup battery to destructive high-temperature reflow
soldering. After a DS1230W 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. DS1230W module bases and DS9034PC PowerCaps are ordered separately and shipped in
separate containers. See the DS9034PC data sheet for further information.
