Product Introduction
The DS1302 RTC module is a low-current charging clock chip that incorporates a real-time clock/calendar and 31-byte static RAM. It communicates with the microcontroller via a simple serial interface. The real-time clock/calendar circuit provides information on seconds, minutes, hours, day, week, month, and year. The number of days in each month and the number of days in leap years can be automatically adjusted. The clock operation can be determined by the AM/PM indication to adopt either 24-hour or 12-hour format. The DS1302 real time clock can communicate with the microcontroller simply in a synchronous serial manner, using only three pins: RST reset, I/O data line, and SCLK serial clock. The read/write data of the clock/RAM is transmitted in a byte or up to 31-byte character group format. When the DS1302 module is operating, its power consumption is very low, with the power consumption when storing data and time information being less than 1mw.
Product Parameter
1. The backup battery is CR2032, with a voltage of 3V and a current of 260mAh. It is a non-rechargeable battery. The theoretical data indicates a retention time of more than 10 years!

Product Application
- Time synchronization in embedded systems: In embedded systems, the real time clock module can serve as the system clock source, providing accurate time information. Through the I2C interface, the microcontroller can read the current time of the real-time clock module and synchronize the time when necessary.
- Timestamp of data recorder: In data recorder applications, the real-time clock module can provide an accurate timestamp for each recorded data item. This is very important for subsequent data analysis and processing.
- Time synchronization in industrial control systems: In industrial control systems, multiple devices need to maintain time synchronization. The real-time clock module can serve as the common clock source for these devices, ensuring the accuracy of time synchronization between them.
- Temperature monitoring: The temperature sensor built into the real time clock module can be used to monitor the environmental temperature. By connecting the real time clock module to the microcontroller, real-time temperature data can be read and processed or displayed.
