FEATURES

§ Provides 10 years of battery backup power for

Nonvolatile (NV) SRAMs in the PowerCap

Module (PCM) package

§ Snaps directly onto a surface-mounted

PowerCap module base to form a complete

NV SRAM module

§ Attaches after module base has been surface-

mounted to protect lithium battery from the

high temperatures of reflow soldering

§ Maintains mechanical and electrical

connection with module base even during

severe shock and vibration stresses

§ Detachment feature allows easy removal

using a regular screwdriver

§ Periodic replacement allows NV SRAM

module life to be extended indefinitely

§ Optional industrial temperature range of

-40°C to +85°C, designated PCI

§ Compatible with these PowerCap module

bases:

§ DS1230YP/ABP/WP

§ DS1245YP/ABP/WP

§ DS1250YP/ABP/WP

§ DS1330YP/ABP/WP

DESCRIPTION

The DS9034PC PowerCap is a snap-on lithium power source for NV SRAMs in Dallas Semiconductor’s

directly surface-mountable PowerCap module base package. After a PowerCap module has been soldered

in place and cleaned, the DS9034PC PowerCap is snapped onto the base to form a complete NV SRAM

module. The PowerCap is keyed to prevent incorrect attachment and is designed to maintain mechanical

and electrical contact with its host module base even during severe mechanical shock and vibration. The

DS9034PC is easily removed by inserting a regular screwdriver into the detachment feature and prying

gently outward and upward to release the PowerCap from the module base.
