The PCF8523TK/1,118 from NXP Semiconductors is a highly integrated CMOS Real-Time Clock (RTC) and calendar designed for applications requiring low power consumption. It provides accurate timekeeping from seconds to years, based on a 32.768 kHz quartz crystal.
This device features a 2-line bidirectional I2C interface with a maximum data rate of 1 MHz, enabling efficient serial communication. Key functionalities include programmable timer and alarm capabilities with interrupt output, a backup battery switch-over circuit for power failure detection, and an offset register for fine-tuning clock frequency. It also includes an oscillator stop detection function and internal Power-On Reset (POR).
The PCF8523TK/1,118 is available in an 8-HVSON (4x4) package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C, making it robust for various environmental conditions. The low backup current, typically 150 nA at 3.0 V, makes it ideal for battery-powered devices and timekeeping applications in metering and other embedded systems.
