Asking for alt.s solution to replace PCF8563TS

Hi Alan,
Here is the customer updated RTC spec. Can BQ32000 or BQ32002 support the spec?

- end-customer expect Vcc can be 5V.
As customer current circuit, there is 1F or 1.5F capacitor for backup power. With 5V Vcc, RTC has more longer back up time (5V to 2.0V or more lower/discharge).
- It’s better to have time correction function.
End-customer got complain from market. As customer spec, timer has to work over 2-weeks. But market users complain the device with big time lag.



Thanks,
SHH

Hi SHH,
Till now, I think TI have no low cost & low power consumption solution to support these new features.
Thanks.
