Product data sheet Rev. 11 — 26 October 2015 5 of 45 NXP Semiconductors PCF8563 Real-time clock/calendar 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. Table 3.
