Latest RTC

[aloon15]

Have used DS1302 but haven't looked at RTC chips for a while and I am wondering / looking for recommendations on new RTC's or just keep using the DS1302. Anyone seen any good one wire RTC's they use? Ok, basically I'm lazy and don't want to research but I find peoples thoughts are better than the spec sheets anyway.

Thanks in advance.

Hi

I did use a DS1307 in a little project but now I am not so sure it the right beast.... Losing time / gaining time issues.

I am curently looking at the obvious alternative the DS3231... I have got as far as ordering some samples of Maxim (Very nice people... Dont ask many questions) So will let you know how I get on.
