DS3231 RTC Memory Module Precise Real Time Clock I2C AT24C32

DS3231 RTC Memory Module Precise Real Time Clock I2C AT24C32 is a low-cost, extremely accurate I2C real-time clock (RTC), with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, disconnect the main power supply and maintains accurate timekeeping. Integrated oscillator improve long-term accuracy of the device and reduces the number of components of the production line RTC DS3231 maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus. Features: Two Time-of-Day Alarms. Digital Temp Sensor Output. Register for Aging Trim. DS3231 RTC Module with 2032 Battery Holder. Highly Accurate RTC Completely Manages All Timekeeping Functions. Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year, with Leap-Year Compensation Valid Up to 2100. Configurable I2C device Address for AT24C32 using SMD jumpers on PCB (A0, A1, A2). Programmable Square-Wave Output Signal. Battery-Backup Input for Continuous Timekeeping. Low Power Operation Extends Battery-Backup Run Time.
