DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line. The DS3231 is available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.\u003c\/span\u003e\n\u003c\/div\u003e  \u003cdiv\u003e   \u003cspan style=\"font-size:14px;\"\u003e2. RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band \/ AM \/ PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus.\u003c\/span\u003e\n\u003c\/div\u003e  \u003cdiv\u003e   \u003cspan style=\"font-size:14px;\"\u003e3. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply. In addition, \/ RST pin is monitored as generating μP reset manually.\u003c\/span\u003e\n\u003c\/div\u003e  \u003cdiv\u003e   \u003cspan style=\"font-size:14px;\"\u003e4. Save time and high precision addition, DS3231 also has some other features that extend the system host of additional features and a range of options. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it (as the same time). This temperature sensor accuracy is ± 3 ° C. On-chip power supply control circuit can automatically detect and manage the main and standby power (i.e., low-voltage battery) to switch between the power supply. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected. When the main power re-power or voltage value returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.\u003c\/span\u003e\n\u003c\/div\u003e  \u003cdiv\u003e    \u003c\/div\u003e  \u003cdiv\u003e   \u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eSpefications:\u003c\/strong\u003e\u003c\/span\u003e\n\u003c\/div\u003e  \u003cdiv\u003e    \u003c\/div\u003e  \u003cdiv\u003e   \u003cspan style=\"font-size:14px;\"\u003e1.
