Ultra-Low Power Real-Time Clock and Calendar IC with 400 kHz I2C Interface for Embedded Systems

The PCF85063TP/1Z is a compact real-time clock (RTC) and calendar IC designed for accurate timekeeping in low-power embedded applications. Developed by NXP Semiconductors, the device maintains precise tracking of seconds, minutes, hours, days, weekdays, months, and years while consuming very low power. It communicates with host microcontrollers through a two-wire I2C interface with speeds up to 400 kHz, making it suitable for modern microcontroller-based designs. This RTC includes integrated alarm, timer, and interrupt capabilities that allow systems to perform scheduled operations or wake from low-power states. Its low current consumption makes it ideal for battery-powered devices such as IoT nodes, smart meters, and portable electronics. The compact HWSON-8 package enables efficient PCB utilisation in space-constrained designs while maintaining reliable timekeeping performance.
