... The 34-pin PowerCap module board is designed with contacts for connection to a separate PowerCap (DS9034PCX) that contains the crystal and battery. This design allows the PowerCap to be mounted on top of the DS1553P after completion of the surface-mount process. Mounting the PowerCap after the surface-mount process prevents damage to the crystal and battery due to the high temperatures required for solder reflow ...
