概述
Description
The DS3231SN# is a highly accurate, I²C real-time clock (RTC) module with an integrated temperature-compensated crystal oscillator (TCXO). It maintains precise timekeeping (±2ppm from 0°C to +40°C) and includes a battery backup for continuous operation during power loss.
Key features:
- Accuracy: ±3.5ppm (±2 minutes/year) across -40°C to +85°C.
- Functions: Tracks seconds, minutes, hours, day, date, month, year (with leap-year correction).
- Alarms: Two programmable time-of-day alarms.
- Outputs: 32kHz output and programmable square-wave signal.
- Power: Operates at 3.3V or 5V, with low power consumption.
Commonly used in data loggers, clocks, and embedded systems requiring reliable timekeeping. The SN# suffix denotes a specific variant or packaging option.
For detailed specs, refer to the Maxim Integrated (now Analog Devices) datasheet.
