DS9034PC/PCI
PowerCap
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

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.
