This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC - but it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully)



  • Real-Time Clock (RTC) Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the week, and Year with Leap-Year Compensation Valid Up to 2100
  • Battery-Backed, General-Purpose RAM with Unlimited Writes
  • I²C Serial Interface
  • Programmable Square-Wave Output Signal
  • Consumes Less than 500nA in Battery-Backup Mode with Oscillator Running.
  • Dimension of 27mm * 28mm * 8.4mm
