M4T28-BR12SH1 (48 mAh) and M4T32-BR12SH1 (120 mAh). For the extended
temperature requirement, the 120 mAh M4T32-BR12SH6 is available. For more information,
see Table 21 on page 40.
Caution: Do not place the SNAPHAT
®
battery/crystal top in conductive foam, as this will drain the
lithium button-cell battery.
The 300 mil SOX embedded crystal SOIC typically requires a user-supplied battery for non-
volatile operation. Capacitor backup can also be implemented with this package.
