RTC Clock Does Not Satisfy WBMS Specification for Sleep Clock Accuracy (SCA) When Internal RCOSC_LF is Used as Clock Source

Revisions Affected:

Revision F and earlier

Details:

The accuracy of the RCOSC_LF clock degrades with decreasing temperature and the compensation algorithm implemented does not compensate for the whole drift for process corner devices. The RTC clock sourced by RCOSC_LF will have reduced accuracy in these cases.

Workarounds:

The workaround is to use the external LF crystal oscillator (XOSC_LF).
