PCF85063A Tiny Real-Time Clock/calendar with alarm function and I2C-bus
■General description
●The PCF85063A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via the two-line bidirectional I2C-bus. Maximum data rate is 400 kbit/s. The register address is incremented automatically after each written or read data byte.
■Features and benefits
▲Provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768 kHz quartz crystal▲Clock operating voltage: 0.9 V to 5.5 V▲Low current; typical 0.22μAat VDD= 3.3 V and Tamb=25℃▲400 kHz two-line I2C-bus interface (at VDD= 1.8 V to 5.5 V) ▲Programmable clock output for peripheral devices (32.768 kHz, 16.384 kHz, 8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz, and 1 Hz) ▲Selectable integrated oscillator load capacitors for CL=7pF or CL= 12.5 pF▲Alarm function▲Countdown timer▲Minute and half minute interrupt▲Oscillator stop detection function▲Internal Power-On Reset (POR)▲Programmable offset register for frequency adjustment
