    Product Details

    SNAPHAT® Lithium Coin Cell Battery with Crystal, STMicroelectronics


    These Battery and Crystal Option devices are detachable lithium power sources housed in special top called SNAPHAT®. The SNAPHAT is snapped on the top of the surface-mounted IC in the Printed Circuit board. Also compatible with the non-volatile TIMEKEEPER® package by STMicroelectronics.

    M4Txx-BR12SH SNAPHAT


    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.

    Features and Benefits


    • 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
