Real Time Clock (DS3231 High Precision)

Introduction:

The DS3231 is a low-cost, extremely accurate I2C?real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.

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.

The DS3231 is available in commercial and industrial?temperature ranges.

The DS3231 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

. The?clock operates in either the 24-hour or 12-hour format?with an?AM/PM indicator.

Two programmable time-of-day?alarms and a programmable square-wave output are?provided. Address and data are transferred serially?through an I2C bidirectional bus. The DS3231 Real Time Clock (RTC) is a highly precise and reliable module used to keep track of accurate time and date in embedded systems, including microcontroller-based projects. This module has a built-in temperature-compensated crystal oscillator (TCXO) that ensures its high accuracy of ?2 ppm over a wide temperature range. It can also communicate over I2C interface with the host microcontroller, allowing it to easily integrate into a variety of projects. In addition to time and date keeping, the DS3231 module also features an alarm function and 56 bytes of non-volatile memory. This makes it suitable for applications that require accurate timing, such as scheduling events, data logging, and controlling actuators at specific times. Overall, the DS3231 RTC module is a versatile and reliable time-keeping solution for embedded systems.
