DS9034PCX
Y2KC nonvolatile timekeeping RAM
GENERAL DESCRIPTION The DS9034PCX PowerCap® is designed to be a
lithium power source for nonvolatile timekeeping RAMs in Dallas Semiconductor’s directly surface-
mountable 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.
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.
PowerCap is a registered trademark of Dallas Semiconductor.
