Description
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. The two-piece solution prevents the battery from
being exposed to the high temperatures of the surface mount process.

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. These sockets were
designed to provide high point contact force to provide the lowest possible contact
resistance. The SNAPHAT® top also incorporates four molded-in retaining clips which hold
onto the ends of the SOIC insuring mechanical and electrical connection even under severe
mechanical shock and vibration. The combined SOIC and SNAPHAT assembly can sustain
shock levels in excess of 100 g without separating. This package also passes variable
frequency testing in accordance with MIL-STD-883, method 2007.2, condition A.
Figure 2 illustrates the affect of repeated insertion and extraction of the SNAPHAT top to the
SOIC. The force required to extract the SNAPHAT, and then to re-insert it, reduces each
time. After four or five extractions, the reduction starts to become unnoticeable and the force
required remains at a fairly constant figure. Typically, though, the SNAPHAT will only need to
be extracted and re-inserted once in its lifetime.

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).
2.2
UL recognition
The M4Zxx-BR00SH has been recognized by Underwriters Laboratories under their
Component Recognition Program and carries U.L. File Number E89556.
2.3
Battery life
For information on data retention life and battery storage life, please refer to the application
note AN1012.
2.4
General notes
ST has conducted experiments using a manual press which determined that if
approximately 60 pounds of force is applied to the top of the SNAPHAT®, battery damage
and/or die cracks could be induced. As Figure 2 on page 6 specifies, only an average of less
than 13 force-pounds is required for proper insertion. We recommend that no more than 40
pounds of force be applied during SNAPHAT® insertion.
If a manual press is employed, it is very important that it be calibrated such that it cannot
exceed this limit.
To remove the SNAPHAT® top for replacement, a DIP/IC extractor tool should be used (see
Figure 4). The SNAPHAT top should be grabbed by the narrow end to avoid bending the
pins.
Caution:
To avoid draining battery do NOT place SNAPHAT pins into conductive foam.
Caution:
To avoid damaging SNAPHAT sockets do NOT wave solder SOIC.
