Cap backup of real time clock
PostPosted: Tue Jul 12, 2005 10:51 am     Reply with quote
Has anyone made a circuit that uses a 1F supercap to backup/keep running
a M41T80M6E Real time clock? I was thinking of using a
panasonic EEC-S5R5V105 Super cap. Vertical mount.

I just want to keep the clock going for 4-5 days with out power,.. and then start back up when power is applied, and have the right time.

I've read the apnotes and such, I just don't have a part to proto-type, and I wanted to know if this has worked for someone.

I did a google search for "Supercapacitor" and "RTC" and found the following on Maxim:

They even show a supercap calculator in the site.
