Description
The MCP79410-I/SN is a versatile, low-power Real-Time Clock/Calendar (RTC) IC designed for high-precision timekeeping. It utilizes a 32.768 kHz quartz crystal to accurately track seconds, minutes, hours, days, dates, months, and years. Equipped with automatic leap-year compensation and 12/24-hour format support, it provides a robust timing reference for a wide array of embedded and IoT applications.
Beyond its timekeeping functions, the MCP79410-I/SN integrates 64 bytes of battery-backed SRAM, allowing for persistent storage of critical data that must survive main power loss. It communicates via an industry-standard I²C interface, making it simple to integrate into digital systems. With its low-power operational profile and reliable battery-backed storage, this RTC is an excellent choice for applications requiring long-term, independent operation.
Key Features
- Comprehensive Calendar: Tracks time and date information with automatic leap-year and month-length adjustments.
- Persistent Memory: 64 bytes of battery-backed SRAM for saving configuration, user data, or system states during power cycles.
- I²C Interface: Reliable, high-speed serial communication for easy integration with microcontrollers.
- Flexible Alarms: Programmable alarm functions for precise scheduling and event triggering.
- Low Power Consumption: Optimized for efficiency in battery-operated and energy-conscious designs.
- Compact Design: Housed in a space-efficient SMD-8 surface-mount package.
Applications
- Embedded Systems: Provides a stable, battery-supported clock reference for custom hardware.
- IoT Devices: Essential for time-stamping sensor data and coordinating time-sensitive network tasks.
- Data Logging: Utilizes the internal SRAM to store timestamps and event data reliably.
- Consumer Electronics: Versatile timing solution for smart appliances, portable devices, and digital hardware.
