                                                                                                  The M4T28-BR12SH1 SNAPHAT top is a detachable lithium power source. 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.

                                                                                                  • Provides battery backup power for non volatile TIMEKEEPER and supervisor devices
