Description
The PCF8563T/F4,118 is a high-efficiency CMOS Real-Time Clock (RTC) and calendar designed specifically for low-power applications. Utilizing a 32.768kHz quartz crystal, it provides comprehensive timekeeping, including year, month, day, weekday, hours, minutes, and seconds, while also featuring an integrated century flag for accurate date tracking. This IC is highly versatile, offering a programmable clock output, a dedicated interrupt output, and an internal voltage-low detector.
Communication is facilitated via a two-line bidirectional I²C-bus at speeds up to 400 kbit/s, with automatic register address incrementing to streamline data read/write operations. Due to its exceptionally low power consumption and robust feature set—including internal power-on reset and integrated oscillator capacitors—it is an ideal choice for mobile devices, portable instrumentation, electronic metering, and any battery-operated product requiring long-term reliable timekeeping.
Key Features
- Efficient Timekeeping: Tracks time/date with century support; operates at voltages as low as 1V at room temperature.
- I²C Interface: High-speed 400kHz two-wire bus for seamless integration with microcontrollers.
- Advanced Control: Includes versatile alarm and timer functions with an open-drain interrupt output.
- Integrated Reliability: Features internal power-on reset (POR) and integrated oscillator capacitors to minimize external component count.
- Compact Footprint: Housed in a standard 8-pin SOIC package suitable for high-density PCB designs.
- Wide Operating Range: Robust performance across -40°C to +85°C.
Applications
- Mobile Telephones: Reliable clock reference for handheld communication hardware.
- Portable Instruments: Perfect for energy-conscious, battery-operated test and measurement equipment.
- Electronic Metering: Provides stable time-stamping for utility billing and consumption data.
- Consumer Electronics: Versatile enough for any product needing a battery-friendly real-time clock.
