M4Txx-BR12SH SNAPHAT


The STMicroelectronics M4T28-BR12SH1 is a battery and crystal within a detachable SNAPHAT package. The SNAPHAT package snaps onto the PCB, directly on top of an SMD SOIC package. This lithium power source is removable which avoids potential issues caused by the heat in surface mounting processes. The M4T28-BR12SH1 works with the ST range of serial real-time clock and non-volatile TIMEKEEPER® SOIC packages, in 28 or 44 pin variants.

The M4T28-BR12SH1 contains a BR1225 48mAh, 3V battery which can be used in temperatures from 0°C to +70°C.

Features and Benefits
