DS3232M Real-Time Clock

Maxim Integrated's low-cost, extremely accurate, I²C real-time clock

Image of Maxim Integrated's DS3232M Real-Time ClockMaxim's DS3232M is a low-cost, extremely accurate, I²C real-time clock (RTC) with 236 bytes of battery-backed SRAM. The device incorporates a battery input and maintains accurate timekeeping when main power to the device is interrupted. The integration of the microelectromechanical systems (MEMS) resonator enhances the long-term accuracy of the device and reduces the part count in a manufacturing line. The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year.

Features Applications
  • Timekeeping accuracy ±5ppm (±0.432 second/day) from -40NC to +85NC
  • 236 bytes of battery-backed user SRAM
  • Battery backup for continuous timekeeping
  • Low power consumption
  • Functionally compatible to DS3232
  • Power meters
  • Industrial applications
