Hi,
we are promoting BQ32000 against PCF8563, do we have spec for the maximum time error after BQ32000 have worked for one day or one year?
Thanks.
Hi Howard,
It is US holiday today. My coworker will get back to you next Monday.

Hao,
thank you.
Waiting for the feedback.
In reply to Howard Zou:
Datasheet indicates pre-calibration accuracy of +/-35ppm. +/-35*10^-6 * 3600 sec/hr * 24hr/day = +/-3.024 seconds per week without calibration
For more information about RTC calibration, see this post: https://e2e.ti.com/support/clock-and-timing/f/48/t/703635
Kind regards,Lane
