DS3231 Real Time Clock Module

Description:

• High Accuracy: Manages all timekeeping functions with an accuracy of ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C.
• Timekeeping Functions: Tracks seconds, minutes, hours, day of the week, date, month, and year with leap-year compensation valid up to 2100.
• Temperature Sensor: Digital output with ±3°C accuracy.
• Special Features: Includes registers for aging trim and a pushbutton reset debounce input (RST).
• Alarms: Two time-of-day alarms available.
• Output Signal: Programmable square-wave.
• Interface: Simple serial interface compatible with most microcontrollers, supporting fast (400kHz) I²C communication.
• Backup Power: Battery-backup input ensures continuous timekeeping during power failures.
• Low Power: Designed for low power consumption to extend battery-backup run time.
• Operating Voltage: 3.3V.

The DS3231 module is designed for precise timekeeping and offers robust features such as temperature-compensated accuracy, multiple alarms, and a straightforward interface for easy integration with microcontrollers.
