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.
