DS1250WP-150-IND DALLAS [Dallas Semiconductor], DS1250WP-150-IND Datasheet - Page 3

• Manufacturer Part Number: DS1250WP-150-IND
• Description: 3.3V 4096k Nonvolatile SRAM
• Manufacturer: DALLAS [Dallas Semiconductor]

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 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. The DS9034PC is keyed to
prevent improper attachment. DS1250W module bases and DS9034PC PowerCaps are ordered separately
and shipped in separate containers. See the DS9034PC data sheet for further information.
