High-Precision Real-Time Clock: DS3231SN is a high-accuracy real-time clock (RTC) that integrates a temperature-compensated crystal oscillator (TCXO) and crystal, making it suitable for applications requiring reliable timing.
Uninterrupted Timekeeping: Maintains accurate timing when main power is disconnected, ideal for critical applications like data logging and industrial systems.
Comprehensive Calendar Functions: RTC stores information for seconds, minutes, hours, weekday, date, month, and year. For months with fewer than 31 days, the end-of-month date is automatically adjusted, including leap year correction. The clock format can be either 24-hour or 12-hour with AM/PM indicators.
Wide Operating Voltage Range: Compatible with 3.3-5.5V power supplies. Easily integrates into various systems, with automatic power switching between main and backup sources for continuous operation.
Programmable Alarms: Supports two calendar alarms and a configurable square wave signal for custom timing needs.
