Simple I2C/SPI RTC
2005-07-31 by James Dabbs
I'm looking for a SPI or I2C real-time clock that only counts seconds. Just a low-power 32-bit counter. Is there such a thing, or do they all have year, month, day of week, etc.? Thanks.

Not what you asked for but 1-wire device DS2415 does that ... Look at www.farnell.com I seem to remember having found an I2C device that did what you require (I usually use farnell to find such things because they have a lot of crap in their inventory and its usually easier to find something in a catalogue than searching through a billion hits on google) Regards lasse

Yes, I believe the Dallas ones are fairly popular.

Think there're several from Dallas/Maxim.. for example DS1371 & DS1374
with I2C interface.
