DS9034PC/PCI PowerCap www.maxim-ic.com FEATURES § § § § § § § § PACKAGE OUTLINE 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 surfacemounted 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: GND VBAT SIDE VIEW TOP VIEW PIN DESCRIPTION VBAT GND - +3V Battery Output - Ground ABSOLUTE MAXIMUM RATINGS § § § DS1230YP/ABP/WP DS1245YP/ABP/WP DS1250YP/ABP/WP Operating Temperature: 0°C to +70°C, -40°C to +85°C for PCI parts Storage Temperature: -40°C to +70°C, -40°C to +85°C for PCI parts § § § DS1330YP/ABP/WP DS1345YP/ABP/WP DS1350YP/ABP/WP BATTERY CHARACTERISTICS Nominal Voltage Nominal Capacity Chemistry Data Retention Life 3V 130mAh Li(CF)X 10 Years (25°C) 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. 1 of 3 100102 DS9034PC/PCI POWERCAP ATTACHMENT POWERCAP REMOVAL 2 of 3 DS9034PC/PCI DS9034PC PACKAGE DIMENSIONS PKG INCHES DIM MIN NOM MAX A 0.845 0.850 0.855 B 0.955 0.960 0.965 C 0.210 0.215 0.220 D 0.065 0.070 0.075 E 0.065 0.070 0.075 ATTENTION: BATTERY COMPONENT The DS9034PC contains a lithium battery.
