Product Overview

Fermion DS3231 precise RTC (breakout). This real-time clock module (RTC) uses the DS3231 chip that integrates a crystal resonator and a temperature compensator which improves the long-term accuracy of the module. In the range of -40°C to +85°C the accuracy of DS3231 remains at ±3.5ppm (±0.3024 seconds/day). The device incorporates a battery input and maintains high precision timing when main power to the device is interrupted. The RTC provides information of seconds, minutes, hours, week, day, month and year and it can automatically adjust the date at the end of the month including corrections for leap year. The clock operates in either the 24hour or 12hour format with AM/PM indicator. Two programmable time of day alarms and a programmable square-wave output are provided. In addition, the RST pin can be used as a push-button input for microprocessor reset.
  • XTAL integrated resonator
  • 840nA timing current and 3.3V-5.5V operating voltage
  • Internal integrated crystal resonator, small deviation
  • Internal integrated temperature compensator, small temperature drift
  • Complete clock calendar function
  • Two programmable time-of-day alarms
  • 0 x 68 I2C address, 1970 to 2100 timing range
  • Working temperature range -40℃ ~ +85℃
  • Timing accuracy: ±3.5ppm (±0.3024 seconds/day)
  • Suitable for event reminder, MCU external wakeup source, clock and alarm output
