FEATURES
Provides 10 years of battery backup power for
Non-volatile SRAMs in the PowerCap
Module (PCM) package
Snaps directly onto a surface-mounted
PowerCap module base to form a complete
Nonvolatile 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 Nonvolatile
SRAM module life to be extended
indefinitely
Compatible with these PowerCap module
bases:
DS1230YP/ABP/WP
DS1245YP/ABP/WP

DESCRIPTION
The DS9034PC PowerCap is a snap-on lithium power source for Nonvolatile 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 Nonvolatile 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.
