PCF85063TP/1Z

The PCF85063TP/1Z 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, including year, month, day, weekday, hours, minutes, and seconds, synchronized with a 32.768 kHz quartz crystal.

This device features a two-line bidirectional I2C-bus interface, supporting a maximum bus speed of 400 kbit/s. The operating voltage range is from 0.9 V to 5.5 V, with typical low current consumption of 0.22 µA at 3.3 V and 25°C. It offers programmable clock output frequencies and an offset register for fine-tuning clock accuracy.

Key features include minute and half-minute interrupts, oscillator stop detection, and an internal Power-On Reset (POR). The PCF85063TP/1Z is supplied in an 8-HWSON (2x3 mm) surface-mount package, making it suitable for space-constrained designs.

Applications for this RTC include digital cameras, printers, copy machines, mobile equipment, and other battery-powered devices where precise timekeeping and low power are critical.
