Replace RTC IC with TI devices

Other Parts Discussed in Thread: BQ32000

Hi Team,

My customer considers to use R2221L for his application.
http://www.ricoh.com/LSI/product_rtc/2wire/r2221/r2221-e.pdf
Is there any TI device that could be alternative?
I would like to suggest TI device to my customer.

I found BQ32000 but Vcc is 3～3.6V and supply current seems more than competitor.
I would also like to know if there is any advantage for TI devices.

I really appreciate if your team suggest the device until tomorrow(26 Feburary).
We must inform the device to my customer by that time.

Best Regards,
Yaita

Yaita,
The BQ32000 is the best solution from TI for this application. Unfortunately, I don't have any competitive slides to share.
Please post on the forum any further support you need.
