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. <\/p>\n

1. Low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.<\/li>\n
2. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping.<\/li>\n
3. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line.<\/li>\n
4. DS3231 available in commercial and industrial temperature ranges, using a 16-pin 300mil SO package.<\/li>\n
5. 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.<\/li>\n
6. 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.<\/li>\n
7. Address and data are transferred serially through an I2C bidirectional bus.<\/li>\n
8. 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.<\/li>\n
9. RST pin is monitored as generating \u03bcP reset manually.<\/li>\n
10. 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.<\/li>\n
11. The device integrates a very precise digital temperature sensor, through the I2C * interface to access it (as the same time).<\/li>\n
12. Temperature sensor accuracy is \u00b1 3 \u00b0 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.<\/li>\n
13. If the main power failure, the device can continue to provide accurate timing and temperature, performance is not affected.<\/li>\n
14. 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.<\/li>\n<\/ol>\n
