DS3231 RTC Module Precise Real Time Clock I2C AT24C32 without cell

DS3231 RTC is a precise real time clock module with a 32 Kbit EEPROM and a built in 10 bit temperature sensor with 0.25°C resolution.

The DS3231 is a low cost and highly accurate I2C real time clock with an integrated temperature compensated crystal oscillator and crystal. It includes a battery input to maintain accurate timekeeping even when main power is lost.

The integrated crystal resonator improves long term accuracy and reduces component count during manufacturing. The DS3231 is available in commercial and industrial temperature ranges and comes in a 16 pin SO package.

Features:

• Two time of day alarms
• Digital temperature sensor output
• Aging trim register
• DS3231 RTC with CR2032 battery holder
• Highly accurate RTC that manages all timekeeping functions
• Counts seconds, minutes, hours, date, month, day, and year with leap year compensation up to 2100
• Configurable I2C address for AT24C32 using PCB jumpers (A0, A1, A2)
• Programmable square wave output
• Battery backup input for continuous timekeeping
• Low power operation extends backup battery life
• RTC voltage supply: 2.2V to 5.5V
• Time format: HH:MM:SS (12 or 24 hour)
• Date format: YY MM DD dd
• 10 bit digital temperature output with ±3°C accuracy and 0.25°C resolution

Package Includes:

• 1 x DS3231 Precise Real Time Clock Module Memory Module
