The IC component PCF2129T/2,518 is a high-accuracy Real-Time Clock (RTC) and calendar module manufactured by NXP Semiconductors. It is designed to provide accurate timekeeping and calendar functions for various electronic devices.
Key Features of PCF2129T/2,518:
1. Timekeeping Accuracy: The PCF2129T/2,518 offers excellent timekeeping accuracy with a typical deviation of only ±3 ppm over the temperature range of -40°C to +85°C. This ensures highly precise time and date calculations.
2. Real-Time Clock: It supports real-time clock functionality and can track hours, minutes, and seconds in both 12-hour and 24-hour formats. The RTC automatically compensates for leap years, ensuring accurate date tracking.
3. Calendar Functions: The PCF2129T/2,518 incorporates a built-in calendar that provides day, month, year, and weekday information. It can determine the correct number of days in each month, including leap years.
4. Battery Backup: To maintain accurate timekeeping during power interruptions, the IC includes a battery backup system. This allows the IC to continue operating from an external power source while the main power is disconnected.
5. I²C Interface: The IC utilizes the I²C (Inter-Integrated Circuit) interface, which allows for easy integration with microcontrollers and other I²C-compatible devices. This interface enables simple communication and configuration settings
