Product Introduction
The RTC DS3231 module is a low-cost, high-precision I2C real-time clock that features an integrated temperature-compensated crystal oscillator (TCXO) and crystal. This device includes a battery input terminal, allowing it to maintain timing even when the main power is disconnected. The integrated crystal oscillator enhances the long-term DS3231 precision and reduces the number of components on the production line. The DS3231 RTC module offers both commercial and industrial temperature ranges and is packaged in a 16-pin 300mil SO package.
The RTC stores information on seconds, minutes, hours, day of the week, date, month, and year. For months with fewer than 31 days, the end-of-month date is automatically adjusted, including corrections for leap years. The clock’s operation format can be either 24-hour or 12-hour format with AM/PM indication. Two configurable calendar alarms and a configurable square wave output are provided.
The DS3231 internally integrates a very accurate digital temperature sensor that can be accessed via the IIC interface (just like time). The on-chip control circuit can perform automatic power detection and manage the power switching between the main power and the backup power source (low-voltage battery).
Product Parameter
1. Operating Voltage: 3.3~5.5V
2. Clock Chip: High-precision clock chip DS3231
3. Clock Accuracy: Within the temperature range of 0℃~40℃, the accuracy is 2ppm, and the annual error is approximately 1 minute
4. Comes with 2 calendar alarms
5. Programmable square wave output
6. Real-time clock generates time measurement for seconds, minutes, hours, day of the week, date, month and year, and provides leap year compensation valid up to the year 2100.
7. The chip is equipped with an internal temperature sensor with an accuracy of ±3℃.
8. Storage Chip: AT24C32 (storage capacity 32K)
9. IIC bus interface, transmission speed 400KHz (when the operating voltage is 5V), can be cascaded with other IIC devices, the 24C32 address can be modified by short-circuiting A0/A1/A2, the default address is 0x57.
10. Comes with battery CR2032, ensuring that the clock continues to operate normally even after the system is powered off.
Product Application
1. 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.
2. 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.
3. 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.
4. 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.
