DS3231S Description

Short technical summary and product information.

The DS3231S is a highly accurate I2C Real-Time Clock (RTC) from Analog Devices / Maxim Integrated, designed to manage all timekeeping functions. It counts seconds, minutes, hours, date, month, day of the week, and year, with leap-year compensation valid up to 2100. The device integrates a temperature-compensated crystal oscillator (TCXO) and crystal for enhanced accuracy.

 

Key features include two programmable time-of-day alarms and a programmable square-wave output signal. The DS3231S operates over a voltage range of 2.3V to 5.5V and consumes low power, extending battery-backup run time. It maintains accurate timekeeping even when the main power supply is interrupted, thanks to its battery-backup input.

 

This RTC is available in a 16-SOIC package and is suitable for surface mount applications. Its operating temperature range is 0°C to 70°C. The simple serial interface connects easily to most microcontrollers, supporting a fast 400kHz I2C interface.

 

Applications for the DS3231S include servers, telematics, utility power meters, and GPS systems where precise timekeeping is critical.
