Logic Diagram s s DESCRIPTION The M4Zxx-BR00SH SNAPHAT top is a detachable lithium power source for ST’s nonvolatile ZEROPOWER surface mount SOIC (MH) package (28 pin). The SNAPHAT top contains a lithium battery and is designed to be "snapped on" after the SOIC is surface mounted on the PC board. Thus the two piece solution prevents the battery from having to be exposed to the high temperatures of the surface mount process. SNAPHAT VBAT– VBAT+ AI02525 November 1999 1/7 M4ZXX-BR00SH MECHANICAL INFORMATION 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 t...
