Description

Caution:

M4T28-BR12SH1 (48mAh) and M4T32-BR12SH1 (120mAh). For the extended temperature

requirement, the 120mAh M4T32-BR12SH6 is available. For more information, see Table 19

on page 39.

Do not place the SNAPHAT battery/crystal top in conductive foam, as this will drain the

lithium button-cell battery.

The 300mil SOX embedded crystal SOIC typically requires a user-supplied battery for non-

volatile operation. Capacitor back-up can also be implemented with this package.
