M4T32-BR12SH6 is a Real-time clock and TIMEKEEPER® SNAPHAT® battery with Crystal. This post will unlock its pinout, datasheet, feature and more about M4T32-BR12SH6.
STMICROELECTRONICS - M4T32-BR12SH6 - BATTERY & CRYSTAL, LITHIUM SNAPHAT-4 M4T32-BR12SH6 is a Real-time clock and TIMEKEEPER? SNAPHAT? battery with Crystal.

The M4T32-BR12SH6 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 SNAPHAT temperatures of the surface-mount process.
Provides battery backup power for the 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 the 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

M4T32-BR12SH6 Battery Discharge Rate
The figure above illustrates the lithium coin cell discharge rate for a given load. This demonstrates the characteristically flat voltage level supplied by the battery until very near the end of its life. These discharge levels have been greatly accelerated in comparison to the normal, actual usage.
