PCF8563TS/5,118 CMOS real-time clock/calendar chip
The PCF8563TS/5,118 from NXP Semiconductors is a low-power CMOS real-time clock/calendar chip optimized for timekeeping applications in battery-powered systems requiring minimal power consumption and high accuracy. This versatile IC provides a complete timekeeping solution with century, year, month, day, weekday, hours, minutes, and seconds functionality in a compact 8-pin SOIC package, operating from a wide voltage range of 1.0V to 5.5V with an extremely low backup current of only 0.25 μA typical at 3.0V. The device features a programmable clock output, alarm function, and timer capability, making it ideal for portable electronics, smart meters, industrial controllers, and consumer appliances where accurate timekeeping with extended battery life is essential.
PCF8563TS/5,118 Key Features
This real-time clock chip utilizes a highly accurate 32.768 kHz crystal oscillator with built-in load capacitors and oscillator compensation circuitry that maintains timekeeping precision across varying temperature conditions. The device features a 400 kHz I²C-bus interface for communication with microcontrollers and supports both slave transmitter and receiver modes with programmable slave addresses. Key functionalities include a programmable clock output frequency (32.768 kHz, 1.024 kHz, 32 Hz, or 1 Hz), a minute-based alarm with interrupt capability, and a down-counting timer that can generate interrupts at programmable intervals. The PCF8563TS/5,118 includes voltage monitoring circuitry that detects power failures and automatically switches to backup power, while the built-in power-on reset function ensures reliable initialization. Operating over the industrial temperature range of -40°C to +85°C, this RTC maintains accuracy with typical timekeeping current of only 0.65 μA at 3.0V, making it exceptionally suitable for long-duration battery operation.
