This RTC chip is one of the best when it comes to accuracy and voltage ranges. It can be used with 3.3v or 5v micros as the ABSOLUTE MAX voltage is 6v. The nominal voltage range is 3.3v to 5.5v. This board holds a CR1220 battery and can last for a long time, the DS3234 uses a max of 2.5\u00a0\u00b5A to keep time. With a CR1220 you have about 48\u00a0mAH. So about 19200\u00a0hrs or 800\u00a0Days (2+ years) without being powered from any other source.<\/p>\n<p><a href=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_top.jpg\"><img loading=\"lazy\" class=\"alignnone size-large wp-image-19\" src=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_top-1024x849.jpg\" alt=\"AtomRTC_top\" width=\"545\" height=\"452\" srcset=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_top-1024x849.jpg 1024w, http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_top-300x249.jpg 300w, http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_top.jpg 1613w\" sizes=\"(max-width: 545px) 100vw, 545px\" \/><\/a><\/p>\n<p>The pin out is as basic as it gets.<\/p>\n<pre><strong>-   = GND<\/strong>\r\n<strong>+   = 3.3v to 5v<\/strong>\r\n<strong>SQW = INT\/SQW (Square Wave Output)<\/strong>\r\n<strong>SI  = MOSI<\/strong>\r\n<strong>SO  = MISO<\/strong>\r\n<strong>CLK = SCK<\/strong>\r\n<strong>SS  = CS<\/strong><\/pre>\n<h2>Datasheet:\u00a0<a href=\"http:\/\/datasheets.maximintegrated.com\/en\/ds\/DS3234.pdf\" target=\"_blank\">DS3234<\/a><\/h2>\n<h2>Schematic:<\/h2>\n<pre><strong><a href=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_SCH.jpg\"><img loading=\"lazy\" class=\"alignnone size-large wp-image-18\" src=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_SCH-1024x449.jpg\" alt=\"AtomRTC_SCH\" width=\"545\" height=\"239\" srcset=\"http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_SCH-1024x449.jpg 1024w, http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_SCH-300x132.jpg 300w, http:\/\/atomsofttech.com\/docs\/wp-content\/uploads\/2015\/02\/AtomRTC_SCH.jpg 1874w\" sizes=\"(max-width: 545px) 100vw, 545px\" \/><\/a> <\/strong><\/pre>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>AtomRTC is a small RTC board based on the DS3234 from MAXIM-IC.
