The MCP79400T-I/MNY is an IC (Integrated Circuit) component manufactured by Microchip Technology. It is a Real-Time Clock (RTC) module that offers accurate timekeeping and timestamping capabilities. Here is an overview and some key features of the MCP79400T-I/MNY:
1. Real-Time Clock (RTC): The MCP79400T-I/MNY provides a precise time reference, keeping track of hours, minutes, seconds, day of the week, day of the month, month, and year. It is capable of operating in 12-hour or 24-hour time formats.
2. Battery Backup: The IC incorporates a battery backup system that ensures timekeeping during power interruptions. It utilizes an external 3V backup power source, allowing it to retain the accurate time even when the main power supply is disconnected.
3. Oscillator and Calibration: The MCP79400T-I/MNY uses an integrated oscillator for timekeeping. Its crystal oscillator can be fine-tuned for improved accuracy by adjusting the calibration registers, compensating for frequency variations.
4. Alarms and Interrupts: This IC supports two independent alarm configurations, enabling alarms for specific date and time events. It can trigger interrupt outputs or wake-up other devices when an alarm event occurs, providing system-wide notifications and control
