Product Description
Product Description
The Waveshare PCF8563 RTC Board is a compact real-time clock module for the I2C bus based on the PCF8563. It provides timekeeping and calendar functions for microcontroller and embedded applications that require a continuous time base independent of the main processor.
Via its I2C interface, the PCF8563 RTC Board can be integrated into typical development and control systems. The feature set of the RTC IC includes real-time clock, calendar, and additional timing functions such as alarm and timer. The board is suitable for applications requiring timestamps, scheduled switching, or periodic wake-up signals.
Technical Features
- Real-time clock module with PCF8563 RTC IC
- Interface: I2C bus
- Suitable for providing time and calendar data
- Supports alarm function
- Supports timer function
- Supports interrupt output
- Supports clock output
- Includes integrated crystal solution for RTC operation
- Provision for backup battery support
Application Areas
The module is suitable for embedded systems, microcontroller projects, data loggers, timing controllers, and industrial prototypes. It can be used wherever autonomous time and calendar tracking is required over a standardized serial interface.
Typical uses include time stamping in measurement systems, periodic wake-up of low-power systems, alarm or reminder functions, and adding RTC capability to controller platforms without an integrated real-time clock. The I2C connection allows integration into many existing hardware platforms with low wiring effort.
