| DS9034PC DS9034PC PowerCap FEATURES PACKAGE OUTLINE * Provides 10 years of battery backup power for Nonvolatile SRAMs in the PowerCap Module (PCM) package * Snaps directly onto a surface-mounted PowerCap module base to form a complete Nonvolatile SRAM module after module base has been surface- mounted to protect lithium battery from the high temperatures of reflow soldering module base even during severe shock and vibration stresses * Attaches * Maintains mechanical and electrical connection with * 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 DS1250YP/ABP/WP DS1330YP/ABP/WP DS1345YP/ABP/WP DS1350YP/ABP/WP PIN DESCRIPTION VBAT GND - +3 Volt Battery Output - Ground ABSOLUTE MAXIMUM RATINGS Operating Temperature Storage Temperature -40C to +85C -40C to +85C BATTERY CHARACTERISTICS Nominal Voltage Nominal Capacity Chemistry Data Retention Life 3 volts 130 mAh Li(CF)X 10 Years (25C) 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. 052798 1/3 DS9034PC POWERCAP ATTACHMENT 1. Align PowerCap contact springs with module base contact lands. 2. Hook PowerCap flange under module base board. Fit Alignment ribs on PowerCap into alignment notches in module base board. 3. Push down slot side of PowerCap until it snaps onto module base. POWERCAP REMOVAL 2. Pull back screwdriver handle slowly until slot side of PowerCap releases from module base. 1. Insert small flathead screwdriver vertically into PowerCap slot. 052798 2/3 DS9034PC DS9034PC PACKAGE DIMENSIONS A B TOP VIEW PKG D DIM A E 0.025" MAX COPLANARITY SIDE VIEW D E 0.065 0.065 0.070 0.070 0.075 0.075 C B C MIN 0.845 0.955 0.210 INCHES NOM 0.850 0.960 0.215 MAX 0.855 0.965 0.220 CONTACT SPRINGS BOTTOM VIEW: REFERENCE ONLY ATTENTION: BATTERY COMPONENT The DS9034PC contains a lithium battery.
