Versatile Real-Time Clock & Calendar

The DS1302N provides accurate timekeeping and calendar capabilities, supporting second, minute, hour, day, date, month, and year resolutions, including automatic leap-year compensation. It supports both 12-hour (with AM/PM) and 24-hour formats, making it adaptable for various time display preferences in electronics design and development.

Power Efficiency and Battery Backup

With a power supply range of 2V to 5.5V and a standby current as low as 2A at 5V, the DS1302N is extremely power efficient. Its automatic battery backup feature ensures reliable data retention for over 10 years at 2V, providing uninterrupted timekeeping even during power failuresideal for long-term embedded applications.

Easy Integration Through 3-Wire Serial Interface

Featuring a simple 3-wire serial interface (SDA, SCL), the DS1302N is easy to interface with most microcontrollers, streamlining the design process. Its DIP-8 form factor and through-hole mounting make it suitable for both prototyping and final PCB designs in various electronic systems and devices.

FAQs of DS1302N:

Q: How do I connect the DS1302N to my microcontroller project?

A: To connect the DS1302N to a microcontroller, use the 3-wire serial interface: connect the Serial Data Input/Output (SDA), Serial Clock Input (SCL), and Chip Enable (CE) to the corresponding pins on your microcontroller. Also, supply it with 2.0V5.5V power and attach an external 32.768kHz crystal to ensure accurate timekeeping.

Q: What are the benefits of using an external 32.768kHz crystal with the DS1302N?

A: An external 32.768kHz crystal provides precise clock oscillation, essential for accurate real-time tracking. This enables long-term stable timekeeping, vital for applications like calendars, data loggers, and electronic clocks.

Q: When does the DS1302N switch to battery backup mode?

A: The DS1302N automatically switches to battery backup mode if the primary power supply (Vcc) fails or drops below the battery voltage. This process is seamless, allowing continuous timekeeping without user intervention.

Q: Where can the DS1302N be effectively used?

A: This RTC module is widely used in microcontroller projects needing reliable time management, such as electronic clocks, data loggers, and calendar systems. Its compatibility with embedded electronics makes it ideal for educational, industrial, and consumer device applications in India and globally.

Q: What process ensures the data retention of the DS1302N for over 10 years?

A: Thanks to its low standby current design and robust battery backup feature, the DS1302N can retain time and calendar data for more than 10 years at 2V, maintaining reliability for extended timekeeping even with infrequent power interruptions.

Q: How does the write protect feature work on the DS1302N?

A: The DS1302N includes an integrated write protect mechanism that can be activated to prevent unintended modification of the time and calendar registers. This ensures your stored time data remains secure during operation.

Q: What is the maximum clock frequency for DS1302N operation, and how does voltage affect it?

A: At 5V supply, the DS1302N supports clock frequencies up to 2MHz. When powered at 2V, the maximum supported frequency is 1MHz. This allows you to optimize performance based on your systems operating voltage.
