Post by thread:[EE]: Best Choice for RTC ?

Hello all, Please indicate me what would be your choice for an Real Time Clock for a system. The cheapest. Thank you. Lucian ____________________________________________

Look at Xicor. They have RTC-only as well as EEROM versions as well as RTC. Work very well. --Bob Lucian Copat wrote: >Hello all, > >Please indicate me what would be your choice for an Real Time Clock for a >system.

Hi, I recommend RS5C313 or RS5C372 from Ricoh. The latter is an I2C one, the former is a 3-Wire bus. Costs $1 or so. Even leap years are maintained.
