It&#8217;s got a couple of handy features, including a rather large cache of nonvolatile FRAM for data storage (8kb on the &#8220;C&#8221; variant, 2kb on the &#8220;B&#8221; variant). That can be useful for applications where some sort of data needs to be stored, like in <a href=\"http:\/\/www.nearfuturelaboratory.com\/projects\/flavonoid\/\">Flavonoid<\/a> where we&#8217;re time-stamping activity measurements, or the <a href=\"http:\/\/www.nearfuturelaboratory.com\/category\/art-technology\/projects\/slow-messenger\/\">Slow Messenger<\/a> where potentially large messages need to be stored. The chip also has a built-in crystal for the actual time keeping part, which reduces the parts count. It communicates using the I2C protocol \u2014 convenient \u2014 and will keep time on a simple low-voltage battery backup or a &#8220;super capacitor&#8221;. (This design uses a small coin-cell, on the back there.)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A bit of overt geekdom here, but we&#8217;ve been getting a few requests for designs that relate to time \u2014 a peculiar watch design for one, and an even more provocative sort of life time-piece.
