The DS1306EN is an integrated circuit (IC) component, designed specifically for real-time clock (RTC) applications. Produced by Maxim Integrated, it offers highly accurate timekeeping functionality and various other features.
One of the key features of the DS1306EN is its ability to provide real-time clock operations even during power outages. This is made possible by an onboard battery backup, ensuring uninterrupted timekeeping. The IC also offers a wide operating voltage range from 2.0V to 5.5V, making it suitable for use with different power supply configurations.
The DS1306EN supports the standard I2C interface, facilitating easy communication with microcontrollers or other digital systems. Through this interface, users can read and write various registers to access different functionalities of the IC. The clock and calendar data are stored in separate registers, making it convenient to track time and date information accurately.
Additionally, the DS1306EN provides features like alarms and timer functions. Users can set multiple alarms for specific time events, enabling the IC to generate an interrupt signal when the set time is reached. The timer function allows for the generation of time-based events by setting a countdown duration.
Furthermore, the DS1306EN offers a programmable square-wave output with a frequency range from 1Hz to 32.768kHz. This feature enables users to generate periodic signals of desired frequencies for various applications, including clock synchronization
