Part Number: BQ32000
Do we have the curve about the " temperature VS time accuracy" or "temperature VS clock"?
And below this post, the customer also need the calibration flow to get the best accuracy, could you please help to send it to me? Thank you very much.
This temperature vs. frequency accuracy curve would be in the datasheet for the 32.768kHz crystal. Please refer to this post for more information about calibration:

In reply to Lane Boyd:
Thank you for your reply, the tested result is that the time skew of BQ32000 is 9s/24h when using the same crystal.
How to explain this phenomenon?
In reply to Kailyn Chen:
Perhaps the variation in board design or contributing to the difference in time skew measured. The value from the datasheet corresponds to 3.024s/24hr. In this case, you could attempt to calibrate the device for your board design to correct the 9s/24hr time skew (~105ppm adjustment).
