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 serial real-time clock, non-volatile TIMEKEEPER®and supervisor devices in the 28- or 44-pin SNAPHAT®SOIC package

Removable battery avoids heat associated with surface-mount process
