7.2 Pin description
[1]
The die paddle (exposed pad) is connected to VSS through high ohmic (non-conductive) silicon attach and
should be electrically isolated. It is good engineering practice to solder the exposed pad to an electrically
isolated PCB copper pad for better heat transfer but it is not required as the RTC doesn’t consume much
power. In no case should traces be run under the package exposed pad.
