1024k Nonvolatile SRAM with Battery Monitor

Dallas Semiconductor -> Maxim Integrated 

DS1345Y/AB

FRESHNESS SEAL

Each DS1345 is shipped from Dallas Semiconductor with its lithium energy source disconnected,

guaranteeing full energy capacity. When VCC is first applied at a level greater than VTP, the lithium

energy source is enabled for battery backup operation.

PACKAGES

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 DS1345 PCM device to be surface mounted without subjecting its lithium backup battery to

destructive high-temperature reflow soldering. After a DS1345 PCM is reflow soldered, a DS9034PC is

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

prevent improper attachment. DS1345 PowerCap Modules and DS9034PC PowerCaps are ordered

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