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 surface- mounted to protect lithium battery from the high temperatures of reflow soldering GND VBAT Maintains mechanical and electrical connection with module base even during severe shock and vibration stresses Detachment feature allows easy removal SIDE VIEW TOP VIEW using a regular screwdriver Periodic replacement allows NV SRAM module life to be extended indefinitely PIN DESCRIPTION Optional industrial temperature range of V - +3V Battery Output BAT -40C to +85C, designated PCI GND - Ground Compatible with these PowerCap module bases: ABSOLUTE MAXIMUM RATINGS Operating Temperature: 0C to +70C, DS1230YP/ABP/WP -40C to +85C for PCI parts DS1245YP/ABP/WP Storage Temperature: -40C to +70C, DS1250YP/ABP/WP -40C to +85C for PCI parts DS1330YP/ABP/WP BATTERY CHARACTERISTICS DS1345YP/ABP/WP Nominal Voltage 3V DS1350YP/ABP/WP Nominal Capacity 130mAh Chemistry Li(CF) X Data Retention Life 10 Years (25C) DESCRIPTION The DS9034PC PowerCap is a snap-on lithium power source for NV SRAMs in Dallas Semiconductors 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 100102DS9034PC/PCI POWERCAP ATTACHMENT POWERCAP REMOVAL 2 of 3
