Description

DS3231 Real Time Clock RTC Module 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 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.
