PCF8563 PCF8563T 8563 I2C RTC Real Time Clock Module Board Fit For Arduino

1、The PCF8563 RTC Board provides the real-time clock/calendar function, which can be driven by a battery on board and works independently even when the MCU is turned off.

2、Low-cost, extremely accurate I2C real-time clock (RTC).

3、More steady and precise than DS1302 or DS1307

4、Support I2C bus cascade (by pin, row seat docking method, which can use multiple I2C module)

5、All the possible elicitations: In addition to the necessary interfaces for SDA and SCL, the INT and COT that may be used are also elicited.

Features:

1. The PCF8563 RTC Board provides the real-time clock/calendar function, which can be driven by a battery on board and works independently even when the MCU is turned off.

2. Low-cost, extremely accurate I2C real-time clock (RTC).

3. More steady and precise than DS1302 or DS1307

4. Support I2C bus cascade (by pin, row seat docking method, which can use multiple I2C module)

5. All the possible elicitations: In addition to the necessary interfaces for SDA and SCL, the INT and COT that may be used are also elicited.

6. Spare 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 be powered normally for ten years.

7. Crystal oscillator: The new original crystal oscillator ensures the stable and accurate travel time of the chip PCF8563.
