Product Description
Description:
- The DS3231 is a high precision real time clock module that maintains hours, minutes and seconds, as well as day, month and year information.
- Operating voltage: 3.3-5V. You can use a typical CR2032 3V battery to power this RTC module, kindly note that the batteries is not included in this listing!
- Specification:
- Clock chip: high-precision clock chip DS3231
- Clock Accuracy range: 0-40 ℃, the accuracy is 2ppm, the error is about 1 minute for a year With 2 Calendar alarm clocks
- Programmable square-wave output
- Real time clock generator seconds, minutes, hours, day, date, month and year timing and provide valid until the year 2100 leap year compensation
- The chip itself is with temperature sensor whose accuracy is around ± 3 ℃
- Memory chips: AT24C32 (storage capacity 32K)
- IIC bus interface, the transmission speed of 400KHz @ working voltage of 5V
●32K - outputs from the DS3231 chip a very accurate 32KHz oscillator
●SQW - outputs a square-wave signal from the DS3231 chip. The frequency of the
square-wave can be changed between 1Hz, 4kHz, 8kHz, or 32kHz programmatically.
this pin can also be used programmed as an interrupt output.
●SCL - input pin for I2C Serial Clock
●SDA - input/output pin for I2C Serial Data
●VCC - power source input pin for the module; can be any voltage from +3.3V to +5.5V DC
●GND - Ground pin connection
●The SCL, SDA, VCC, and GND pins at the right side of the module are
connected internally at the left side pins with the same label.
Note: Working with the RTC requires two important steps: 1, Setting the current time, so that the RTC knows what time it is. 2, Retaining the time, so that the RTC module always gives the correct time, even when it is turned off.
Can be cascaded with other IIC device, 24C32 addresses can be shorted A0/A1/A2 modify default address is 0x57
