High-precision real-time clock (RTC) module equipped with the SD3031 chip. It has an integrated quartz resonator and temperature compensator, which significantly improves the stability and accuracy of the module, and also ensures high precision of synchronization. The module is powered by a coin cell battery (not included), thanks to which it measures time also in the absence of power from another source. The RTC tracks seconds, minutes, hours, days of the week, months and years. It also automatically adjusts the date to the end of each month and includes leap year adjustments. The SD3031 has a built-in 70-byte SRAM for low-power data storage.
Main features:
- Low power consumption, operating current of 1.8 µA when powered by a coin cell battery
- High working precision of ± 3.8 ppm at 25 °C
- Integrated temperature compensator
- Built-in 70-byte SRAM
Specification:
- Supply voltage: 3.3 V
- Communication interface: I2C bus
- I2C address: 0x32
- Year measurement range: from 2000 to 2099
- Operating environment temperature: -10 °C to 70 °C
- Timing accuracy: ±3.8 ppm at 25 °C
- Product size: 22.5 x 21 mm
