Introduce real-time clock (RTC) functionality to the design using the RTC 2 Click Board™. This add-on board features a low-power Maxim DS1307 serial real-time clock (RTC). It is a full binary-coded decimal (BCD) clock/calendar with a programmable square-wave output signal. The board uses a standard I2C interface for communication with the target host microcontroller. RTC2 Click Board™ has a 3V/230mA lithium battery that works as a backup power supply. The timekeeping function continues even when the power supply status is OFF. Real-Time Clock (RTC) counts seconds, minutes, hours, date of the month, month, day of the week, and year with leap-year clock function with a four-year calendar. It is designed to operate a 5V power supply only. In order to function to a 3.3V system, the user can check to go for RTC Click Board™.
The RTC2 Click Board™ is an ideal option who applications involving real-time clocks, calendars, and programmed alarms.

Product Description
Product Description
The RTC2 Click Board™ is an accessory board in mikroBus™ form factor. It features the DS1307 serial real-time clock (RTC). It is a low-power, full binary-coded decimal (BCD) clock/calendar with programmable square-wave output signal. Board uses I2C interface for communication, and can only use 5V power supply. Board features a 3V/230mA lithium battery as a backup power supply which ensures that timekeeping operation continues even when the main power supply goes OFF.
IC/module: DS1307 Serial Real-Time Clock
DS1307 is a full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The clock is designed to operate in either the 24-hour or 12-hour format with AM/PM indicator. It detects power failures and automatically switches to the backup supply. It completely manages all timekeeping functions.
Note: The RTC2 Click Board™ is intended to be used with a 5V power supply only.
