The is a SNAPHAT® lithium coin Cell Battery provides battery backup power for non-volatile ZEROPOWER® SRAM device. The SNAPHAT is snapped on the top of the surface-mounted IC in the printed circuit board. The two-piece solution prevents the battery from being exposed to the high temperatures of the surface-mount process. Electrical connection to the SOIC is made through two pins that connect to the press fitted sockets at one end of the SOIC. Critical contact points between the pins and sockets are gold-plated to resist oxidation. Internally, each socket contains six independent contact fingers to form redundant connections between the two components. These sockets were designed to provide high point contact force to provide the lowest possible contact resistance.
