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,
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
