Part Overview
Description
The DS3231M is a highly accurate, low-cost, 12C real-time clock (RTC) with an integrated MEMS resonator. It maintains accurate timekeeping even during power interruptions thanks to its battery input. The DS3231M is compatible with the popular DS3231 RTC and offers the following features:
Complete clock calendar functionality (seconds, minutes, hours, day, date, month, year) with leap year compensation up to 2100
Timekeeping accuracy of ±5ppm (±0.432 seconds/day) from -45°C to 85°C
Two programmable time-of-day alarms
1Hz and 32.768kHz outputs
Reset output and pushbutton input with debounce
Digital temperature sensor with ±3°C accuracy
2.3V to 5.5V supply voltage
Simple serial interface (12C) with a fast 400kHz speed
Battery-backup input for continuous timekeeping
Low power operation for extended battery-backup run time
