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.
Programmable clock output for peripheral devices
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
