DS3231 is a low-cost, extremely accurate I2C module realtime clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. Use in commercial and industrial applications 16-pin 300 miles.
The RTC provides seconds, minutes, hours, day, date, month and year. Functions: Less than 31 days, the date of termination, a correction for the leap year. AM / PM. Two configurable alarms, and a calendar. Addresses and data are transmitted through the I2C bus.
- IIC interface, the maximum transmission speed of 400KHz (5V)
- Can be cascaded with other IIC devices, 24 C 32 A0/A1/A2, the default address is 0x57
- Battery LIR2032, to ensure the fuses during a power failure.
