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 avoids the battery and

crystal from having to be exposed to the high tem-

peratures of the surface mount process.
