PCF8563T module clock module RTC module

• All possible exports: In addition to the two necessary ports, SDA and SCL, the 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 for ten years.
  Crystal oscillator: Brand new original authentic crystal oscillator, to ensure the stability of the chip PCF8563, accurate travel time.
  The advantages of the chip itself: In the actual project of the owner, a variety of clock chips have been applied, and this Philips chip is found to be the most stable, most accurate, and lowest power consumption. Clock chips like DS1302 are really weak. PCF8563 clock chip is highly recommended.
  Price advantage: We are a manufacturer. We have an absolute advantage in terms of price. We can do it at a price that other people can do (the batch price is better).
  I. PCF8563 clock chip introduction

• PCF8563 is an industrial-grade multifunction clock / calendar chip with extremely low power consumption that includes the I2C bus interface function introduced by PHILIPS. PCF8563's multiple alarm functions, timer functions, clock output functions, and interrupt output functions can complete a variety of complex timing services, and even provide a watchdog function for the microcontroller. Is a very cost-effective clock chip, it has been widely used in electric meters, water meters, gas meters, telephones, fax machines, portable instruments and battery-powered instruments and other product areas.
