DS3231 REAL TIME CLOCK MODULE – RTC

DS3231 REAL TIME CLOCK MODULE – RTC in Pakistan High Accuracy DS3231 Precise Real Time Clock Module with 32Kbit EEPROM and a built-in 10-bit temperature sensor having a resolution of 0.25C.The DS3231.The DS3231 Precise Real Time Clock Module is a low-cost The device incorporates a battery input and maintains accurate timekeeping when the main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line.

DS3231M is an extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator.

Save precious cycles on your micro as the RTC maintains seconds, minutes, hours, day, date, month, and year information in easy-to-access registers. On top of that, the DS3231M manages leap years and has two configurable alarm clocks.
