DS3231SN#T&R Description

Short technical summary and product information.

The DS3231SN#T&R is an extremely accurate I2C Real-Time Clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal, manufactured by Analog Devices / Maxim Integrated. This device manages all timekeeping functions, including seconds, minutes, hours, date, month, day of the week, and year, with leap-year compensation valid up to 2100.

 

Key features include high accuracy, with ±2ppm from 0°C to +40°C and ±3.5ppm from -40°C to +85°C. It offers a digital temperature sensor output with ±3°C accuracy. The RTC supports both 12-hour and 24-hour formats, includes two programmable time-of-day alarms, and a programmable square-wave output signal. The simple serial interface utilizes a fast 400kHz I2C bus.

 

Designed for continuous timekeeping, the DS3231SN#T&R includes a battery-backup input and operates at low power, extending battery-backup run time. It is available in a 16-pin SOIC package suitable for surface mounting. The operating temperature range is -40°C to +85°C, making it suitable for industrial applications.

 

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