STMicroelectronics M4T32-BR12SH1 2.8V 120mAh SNAPHAT Lithium Battery and Crystal IC

STMicroelectronics M4T32-BR12SH1 2.8V 120mAh SNAPHAT Lithium Battery and Crystal IC

The STMicroelectronics M4T32-BR12SH1 is a SNAPHAT battery and crystal IC made for compatible TIMEKEEPER and serial real-time clock surface-mount SOIC packages. Its detachable SNAPHAT design allows the battery and crystal top to be installed after surface mounting, helping keep the battery away from reflow heat during board assembly.

This part combines a lithium power source and crystal in one snap-on package for backup and clock support. It is built for compatible 28-pin and 44-pin SOIC applications that use the STMicroelectronics SNAPHAT format for memory backup and timekeeping functions.
