DS3231SN
Brand: Analog Devices
The DS3231SN integrates a crystal and temperature-compensated oscillator into a single 16-pin SOIC, delivering ±2 ppm real-time-clock accuracy from 0°C to +40°C without any external timing components. A VBAT battery-backup input keeps the calendar running through main-supply outages, and a simple I²C interface at up to 400 kHz drops straight into any microcontroller design.
