DESCRIPTION

The DS9034PCX PowerCap is designed to be a lithium power source for Nonvolatile Time-keeping

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.
