 The [[http://macetech.com/store/index.php?main_page=product_info&cPath=5&products_id=8|ChronoDot RTC]] is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC (TCXO). It includes a CR2016 battery which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required. The [[http://macetech.com/store/index.php?main_page=product_info&cPath=5&products_id=8|ChronoDot RTC]] is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC (TCXO).

-The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges...the ChronoDot will drift less than a minute per year. This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock. Here is a live demo of a DS3231 chip that has been keeping time since it was last synchronized in 2005: [[http://www.maxim-ic.com/products/timers/DS3231_demo/|DS3231 Web Demo]]+The DS3231 has an internal crystal and a switched bank of tuning capacitors.

 The ChronoDot will plug into a standard solderless breadboard and also has mounting holes for chassis installation. The ChronoDot will plug into a standard solderless breadboard and also has mounting holes for chassis installation.
