Product details

Description

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperaturecompensated crystal oscillator (TCXO) and crystal.

The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted.

Features

Highly Accurate RTC Completely Manages All Timekeeping Functions.
Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year, with Leap-Year Compensation Valid Up to 2100.
Accuracy ±2ppm from 0°C to +40°C.
Accuracy ±3.5ppm from -40°C to +85°C.
Digital Temp Sensor Output: ±3°C Accuracy.
Register for Aging Trim.
RST Output/Pushbutton Reset Debounce Input.
Two Time-of-Day Alarms.
