DESCRIPTION

The DS9034PCX PowerCap is designed to be a

snap–on lithium power source for Nonvolatile Time-

keeping RAMs in Dallas Semiconductor’s directly sur-

face–mountable PowerCap Module (PCM) package.

After a PowerCap Module Board has been soldered in

place and cleaned, the DS9034PCX PowerCap is

snapped 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.
