SUMMARY DESCRIPTION
The M4TXX-BR12SH SNAPHAT top is a detach-
able lithium power source for ST’s non-volatile
TIMEKEEPER surface-mount SOIC (MH) pack-
age (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 tem-
peratures of the surface mount process.
