19-5584; Rev 10/10 DS9034PCX PowerCap with Crystal www.maxim-ic.com GENERAL DESCRIPTION FEATURES The DS9034PCX PowerCap is designed to be a lithium power source for nonvolatile timekeeping RAMs in Dallas Semiconductor’s directly surfacemountable PowerCap Module (PCM) package. After a PowerCap module board has been soldered in place and cleaned, the DS9034PCX PowerCap is placed on top of the PCM board to form a complete PowerCap module package. The PowerCap is keyed to prevent incorrect attachment. Provides 10 Years of Battery Backup Power for Nonvolatile Timekeeping RAMs in the PowerCap Module Package (PCM) Snaps Directly Onto Surface-Mounted PowerCap Module Boards Detachment Feature Allows Easy Removal Compatible with these 34-Pin PowerCap Module Boards: The DS9034PCX can be easily removed by inserting a regular screwdriver into a detachment feature and prying gently outward and upward to release the PowerCap from the PowerCap module board.
