M4Z28-BR00SH M4Z32-BR00SH ZEROPOWER® SNAPHAT® battery Datasheet - production data Description The M4Zxx-BR00SH SNAPHAT® top is a detachable lithium power source for ST’s nonvolatile ZEROPOWER® surface-mount SOIC 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. The two-piece solution prevents the battery from being exposed to the high temperatures of the surface-mount process.

Mechanical information 2 M4Z28-BR00SH, M4Z32-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.
M4Z28-BR00SH, M4Z32-BR00SH 2.1 Mechanical information Battery characteristics Figure 3 on page 8 illustrates the lithium coin cell discharge rate for a given load. This demonstrates the characteristically flat voltage level supplied by the battery until very near the end of its life. These discharge levels have been greatly accelerated in comparison to the normal, actual usage. Note: These batteries contain no mercury (Hg), cadmium (Cd), or lead (Pb). 2.
