PCF8563
Real-time clock/calendar
Rev. 11 — 26 October 2015
Product data sheet
1. General description
The PCF8563 is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power
consumption. A programmable clock output, interrupt output, and voltage-low detector are
also provided. All addresses and data are transferred serially via a two-line bidirectional
I2C-bus. Maximum bus speed 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
Century flag
Clock operating voltage: 1.0 V to 5.5 V at room temperature
Low backup current; typical 0.25 A at VDD = 3.0 V and Tamb = 25 C
400 kHz two-wire I2C-bus interface (at VDD = 1.8 V to 5.5 V)
Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz, and
1 Hz)
Alarm and timer functions
Integrated oscillator capacitor
Internal Power-On Reset (POR)
I2C-bus slave address: read A3h and write A2h
Open-drain interrupt pin
3. Applications
Mobile telephones
Portable instruments
Electronic metering
Battery powered products

[1] The die paddle (exposed pad) is connected to VSS through high ohmic (non-conductive) silicon attach and
should be electrically isolated. It is good engineering practice to solder the exposed pad to an electrically
isolated PCB copper pad for better heat transfer but it is not required as the RTC doesn’t consume much
power. In no case should traces be run under the package exposed pad.
