  • 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.
  • DS3231 available in commercial and industrial  temperature ranges, using a 16-pin 300mil SO package.
  • 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.
  • 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.
  • 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. 
  • /RST pin is monitored as generating μP reset  manually.
  • 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).
  • 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.
