M4T32-BR12SH1属于集成电路（IC）的IC电池。由意法半导体集团制造生产的M4T32-BR12SH1IC 电池该产品族的中产品是用来给应用中实时时钟供电的专用模块，包含电化学电源，在外部电源缺失时追踪时间的流逝。这些产品通常用于特定的计时集成电路，提供了一个温度敏感型组件的组装解决方案，可在其他高温组装过程完成之后，再将其组装到印刷电路板上。

描述 Description

The M4TXX-BR12SH SNAPHAT® top is a detachable lithium power source for ST’s nonvolatile TIMEKEEPER® surface-mount SOIC (MH) 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.
