Hi,
When checking the performance of devices built on the basis of the processor MSP430F5529,
a defect of "leaving" the time ahead (RTC failure) was detected.
We use quartz p/n KX-327XS 32.768 kHz.
A-B and A-B-A swap is already done.
When the MSP430F5529IPPG was replaced, the problem was solved.
However, 80 pcs. (from 2000) are potentially defective.
Please tell me, what could be the reason?
WBR,
Anastasia
