Product Summary

The DS3231SN is a low-cost, extremely accurate I2C realtime clock (RTC) with an integrated temperature compensated crystal oscillator (TCXO) and crystal. The DS3231SN incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231SN is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. Its applications include servers, utility power meters, telematics, GPS.
