All that may be used are exported: In addition to the two necessary ports of SDA and SCL, INT and COT that may be used are also exported.
Backup battery: When the system is powered off, the backup battery supplies power to the PCF8563 chip. The low power consumption of the PCF8563 ensures that the battery can supply power normally for ten years.
Crystal oscillator: The new original crystal oscillator ensures the stable and accurate timekeeping of the chip PCF8563.
Advantages of the chip itself: In the actual project of the shop owner, he has applied a variety of clock chips and found that this Philips chip is stable, accurate in time and power consumption. Clock chips like DS1302 are simply weak, and the PCF8563 clock chip is highly recommended.
Price advantage: We are a manufacturer, we have some advantages in price, and we can do it at a price that other companies can do (batch price is better).

PCF8563 clock chip introduction:
PCF8563 is an industrial-grade multi-function clock/calendar chip with very low power consumption with I2C bus interface function introduced by PHILIPS. The multiple alarm functions, timer functions, clock output functions, and interrupt output functions of PCF8563 can complete various complex timing services, and even provide watchdog functions for the microcontroller. It is a very cost-effective clock chip, which has been widely used in the fields of electricity meters, water meters, gas meters, telephones, fax machines, portable instruments and battery-powered instruments.
