PCF85063TP/1Z Datasheet PDF - NXP

The PCF85063TP/1Z is a CMOS Real-time Clock (RTC) and Calendar optimized for low power consumption. It provides year, month, day, weekday, hours, minutes and seconds based on a 32.768kHz quartz crystal. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via the two-line bidirectional I²C-bus. Maximum bus speed is 400kbps. The register address is incremented automatically after each written or read data byte.

● Minute and half minute interrupt

● Oscillator stop detection function

● Internal power-ON Reset (POR)

● Programmable offset register for frequency adjustment

● Selectable integrated oscillator load capacitors for CL=7pF or CL=12.5pF
