    This fits your .
  • Make sure this fits by entering your model number.
  • DS3231 is a low-cost, high-precision I2C real-time clock (RTC) with integrated temperature-compensated crystal oscillator (TCXO) and crystal. The integrated crystal oscillator improves the long-term accuracy of the device and reduces the number of components in the production line.
  • The module contains a battery input, which can maintain accurate timing when the main power is disconnected. RTC saves seconds, minutes, hours, day, date, month, and year information. Months less than 31 days will automatically adjust the end of the month, including corrections for leap years. The working format of the clock can be 24 hours or a 12-hour format with / AM / PM indication.
  • Provide two configurable calendar alarms and a configurable square wave output. The address and data are transferred serially through the I2C bidirectional bus.
  • Precise, temperature-compensated voltage reference and comparator circuits are used to monitor VCC status, detect power failures, provide reset output, and automatically switch to backup power when necessary. In addition, the / RST monitor pin can be used as a manual input to generate a μP reset.
  • A very accurate digital temperature sensor is integrated inside, which can be accessed through the I2C * interface (just like time).
