DS3231MZ Real Time Clock Module, I2C Interface, High Accuracy TCXO, Battery Backup, SOP-8 Package, for Industrial Arduino Raspberry Pi DIY Projects(A)
【HIGH-ACCURACY TIMEKEEPING】- Integrated temperature-compensated crystal oscillator (TCXO) ensures precise timekeeping with low drift, ideal for applications requiring reliable long-term timing.
【BATTERY BACKUP & LOW POWER】- Features a backup battery input to maintain continuous timekeeping during main power loss, with ultra-low power consumption to extend battery life in standby mode.
【COMPLETE CALENDAR & ALARM FUNCTIONS】- Provides full clock calendar including seconds, minutes, hours, day, date, month, and year with automatic leap year compensation until 2100, plus two programmable time-of-day alarms.
【BUILT-IN TEMPERATURE SENSOR】- Includes an on-chip digital temperature sensor with ±3°C accuracy, offering convenient ambient temperature monitoring without additional components.
【EASY I2C INTERFACE & WAVEFORM OUTPUT】- Communicates via a standard 400kHz I2C bus for simple microcontroller integration and offers configurable square wave outputs (e.g., 1Hz, 32.768kHz) for system synchronization.
