The IC component MCP79412T-I/MNY is a real-time clock/calendar (RTCC) device manufactured by Microchip Technology. It is among the most popular choices for embedded systems that require accurate timekeeping and event scheduling capabilities. Below is an overview of the key features and functionalities offered by MCP79412T-I/MNY:
1. Real-Time Clock (RTC) Functionality: The MCP79412T-I/MNY has a built-in oscillator that provides precise timekeeping with an accuracy of ±20 ppm. It enables the tracking of time in hours, minutes, seconds, days, months, and years. It takes into account leap years and supports both 12-hour and 24-hour time formats.
2. Alarm and Event Management: The device supports up to two programmable alarms, which can trigger an interrupt signal or perform specific actions when a specified time is reached. It also offers a power-fail detection feature to prevent data loss during unexpected power outages and a power-on reset functionality.
3. Battery Backup: MCP79412T-I/MNY has a built-in power-fail comparator that operates on a separate VBAT pin. This pin allows connection to a backup battery, such as a coin cell, to provide continuous timekeeping and backup power to the clock and alarm registers. The low-power consumption of the device ensures extended battery life
