Product Description

The PCF8563TS/5 is a low-power real-time clock (RTC) IC designed for surface mount applications, featuring an I²C-bus interface for seamless integration with microcontrollers. It operates within a wide voltage range of 1.0V to 5.5V, ensuring compatibility with diverse power sources, and supports industrial temperature ranges (-40°C to +85°C). This RTC IC includes a 32.768 kHz oscillator, programmable clock output, and two interrupt outputs for alarm functions. With ultra-low current consumption (typ. 0.25 µA at 3V), it excels in battery-backed systems such as smart meters, IoT devices, and industrial automation. Key advantages include high accuracy (±3 ppm), compact TSSOP8 package, and built-in voltage monitoring. While lacking an internal battery, it efficiently manages external backup power. Not applicable for screen-based or proximity-sensing applications, its focus remains on precise timekeeping and system event triggering.
