PCF85063ATL
Tiny Real-Time Clock/calendar with alarm function and
I2C-bus
Rev. 2 — 15 April 2013
Product data sheet
1. General description
The PCF85063ATL 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.
2. 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 0.27 A at VDD = 3.0 V and Tamb = 25 C
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 = 7 pF or CL = 12.5 pF
