STMicroelectronics M4T28-BR12SH1, Battery Backup IC, 2.8 V 4-Pin, SNAPHAT
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.
The M4Txx-BR12SH SNAPHAT®top is a detachable lithium power source for STs 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.
