Product Description

Describe

The DS3231 is a low-cost, high-accuracy I2C real-time clock (RTC) featuring an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device includes a battery input terminal, enabling precise timekeeping even when the main power supply is disconnected. The integrated crystal enhances long-term accuracy and reduces the number of components required on the production line. The DS3231 is available in commercial- and industrial-grade temperature ranges and is packaged in a 16-pin, 300-mil SO package.
The RTC stores information for 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 correction for leap years. The clock can operate in either a 24-hour format or a 12-hour format with AM/PM indication. It provides two programmable calendar alarms and one programmable square-wave output. Address and data are transmitted serially over the I2C bidirectional bus.
A precision, temperature-compensated voltage reference and comparator circuit is used to monitor the VCC status, detect
power-supply faults, generate a reset output, and automatically switch to the backup power supply when necessary. In addition, the /RST monitoring pin can serve as a manual input for generating a microprocessor reset.
In addition to its high timing accuracy, the DS3231 offers several other features that expand the system host’s functionality and design options. The device integrates a highly accurate digital temperature sensor that can be accessed via the I2C* interface—just like the timekeeping function. This temperature sensor has an accuracy of ±3°C. An on-chip control circuit provides automatic power-supply detection and manages seamless switching between the main power supply and the backup power source (i.e., a low-voltage battery). Even if the main power supply fails, the device continues to provide precise timing and temperature readings without any degradation in performance. When the main power is restored or the supply voltage returns to within the allowable range, the on-chip reset function can be used to restart the system microprocessor.

Module parameters:
1. Dimensions: 38 mm (length) × 22 mm (width) × 14 mm (height)
2. Weight: 8g
3. Operating voltage: 3.3–5.5 V
4. Clock Chip: High-Precision DS3231 Clock Chip
5. Clock accuracy: Within the temperature range of 0–40°C, the accuracy is 2 ppm, resulting in an annual error of approximately 1 minute.
6. Comes with 2 calendar alarms
7. Programmable Square Wave Output
8. The real-time clock provides second, minute, hour, day of the week, date, month, and year timing, and includes leap-year
compensation valid through the year 2100.
9. The chip features a built-in temperature sensor with an accuracy of ±3°C.
10. Memory chip: AT24C32 (storage capacity: 32 KB)
11. I²C bus interface, with a maximum transmission speed of 400 kHz (at a supply voltage of 5 V).
12. Can cascade with other I²C devices; the 24C32 address can be configured by shorting A0, A1, and A2, with the default address being 0x57.
13. Equipped with a CR2032 battery to ensure the clock continues to keep accurate time even after a power outage.
14. Packaging method: individual antistatic packaging

Wiring instructions (using Arduino Uno R3 as an example):
SCL→A5
SDA→A4
VCC→5V
GND→GND

This EGS002 driver module works well for my inverter. It’s a bit larger than I imagined, but it still fits in my enclosure and functions as it should.
