概要
Description
- I²C Interface: Supports communication with microcontrollers.
- Low Power Consumption: Ideal for battery-operated devices.
- Timekeeping Accuracy: Maintains seconds, minutes, hours, day, date, month, and year (with leap-year correction).
- Battery Backup: Operates down to 1.3V, ensuring time retention during power loss.
- Alarm & Timer Functions: Configurable interrupts for system wake-ups.
- Wide Temp Range: Operates from -40°C to +85°C, suitable for industrial applications.
Commonly used in embedded systems, smart meters, and IoT devices, the M41T62LC6F ensures reliable timekeeping with minimal power draw. Its small SOIC-8 package makes it space-efficient for compact designs.
For detailed specs, refer to the datasheet.
Equivalent
