M4T32-BR12SH：SNAPHAT® 120 mAh lithium coin cell battery with crystal

The M4Txx-BR12SH SNAPHAT^®top is a detachable lithium power source for ST’s serial real-time clock and non-volatile TIMEKEEPER^®surface-mount SOIC package (28- and 44-pin).

The SNAPHAT top contains both the battery and crystal 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 and crystal from being exposed to the high temperatures of the surface-mount process.
