  • The M4Txx-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- 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 temperatures of the surface-mount process.

    Key Features

    • 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
    • Snaps directly onto surface-mounted SNAPHAT SOIC
    • Choice of battery capacities
      • M4T28-BR12SH = 48 mAh
      • M4T32-BR12SH = 120 mAh
    • Keyed insertion to ensure proper assembly
    • Removable for replacement and proper disposal
    • Pb-free package
    • Available in Ecopack®packages, tubes
