The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date 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 AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.

The DS1307 Real Time Clock (RTC) module is a widely used component in electronics and embedded systems for keeping accurate time. Here are some key features and details about the DS1307 RTC module:
Key Features:
- Real-Time Clock (RTC): Keeps track of the time in hours, minutes, and seconds, along with the date, month, and year with leap year compensation.
- I2C Interface: Communicates with microcontrollers via the I2C bus.
- Battery Backup: This can maintain accurate timekeeping even when the main power supply is interrupted, thanks to a backup battery (typically a CR2032 coin cell).
- Low Power Consumption: Consumes minimal power, making it suitable for battery-operated devices.
- Clock Oscillator: Uses an external 32.768 kHz crystal oscillator.
Pin Configuration:
- VCC: Power supply (typically 5V).
- GND: Ground.
- SCL: Serial Clock Line for I2C communication.
- SDA: Serial Data Line for I2C communication.
- SQW/OUT: Square wave output pin that can be used for outputting a programmable square wave.
Basic Operation:
- Connecting to a Microcontroller: The DS1307 RTC module is connected to the microcontroller via the I2C bus (SCL and SDA lines). The microcontroller can then read from and write to the RTC to get the current time or set a new time.
- Setting the Time: To set the time, the microcontroller sends the desired time data over the I2C bus to the DS1307.
- Reading the Time: To read the current time, the microcontroller requests time data from the DS1307 over the I2C bus.
Common Applications:
- Clocks and Watches: Provides accurate timekeeping for digital clocks and watches.
- Data Loggers: Timestamping data entries in data logging applications.
- Alarm Systems: Scheduling tasks or triggering events at specific times.
- Home Automation: Time-based control of appliances and systems in smart homes.
