The device includes a built-in temperature-compensated crystal oscillator (TCXO) for improved accuracy over temperature variations.

Features:

• Low Power Consumption: 400nA timekeeping current (typical)
• Wide Supply Voltage Range: 2.7V to 5.5V
• I²C Interface: Up to 400kHz communication speed
• Battery Backup Support: Maintains timekeeping during power loss
• Two Time-of-Day Alarms: Programmable alarms with interrupt output
• Automatic Leap Year Compensation: Up to year 2100
• Temperature Compensation: Improves oscillator accuracy
• Small Footprint: Available in a 16-pin SOIC package
• Industrial Temperature Range: -40°C to +85°C

This RTC is commonly used in embedded systems, IoT devices, and industrial applications requiring precise timekeeping with low power consumption.
