Key Features:

  • Provides battery backup power for serial real-time clock, non-volatile TIMEKEEPER® and supervisor devices in the 28-pin SNAPHAT® SOIC package
  • Removable battery avoids heat associated with surface-mount process
  • Snaps directly onto surface-mounted SNAPHAT SOIC
  • Keyed insertion to ensure proper assembly
  • Removable for replacement and proper disposal

The M4T28-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-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.
