Serial Real-Time Clocks
Embedded Crystal Packaging

ST's popular line of Serial Real-Time Clocks now has a new packaging option - Embedded Crystal Packaging. In addition to standard features such as integrated battery switchover and write protect, we now include the crystal, thereby bringing many more benefits to the user.

The Embedded Crystal Package (SOX28, "MX" suffix) is now an option on four different Serial RTCs. SOX28 samples of all four are available now, and the M41T81MX6 and M41ST95WMX6 are at production status.
