TPS659113 RTC: Delay 1s after 20 min

Chris Meng

Hi,

We are using RTC on TPS659113 on IPNC app. We found the RTC time will dealy 1s after 20 minutes compared with PC timer.

Is this reasonable? What's the accuracy of the RTC on TPS659113? What may cause this problem?

Hi,

Are you using external crystal or internal oscillator?

Accuray for the internal oscillator is +/- 15% on page 12 of datasheet.
