Real-time clock/calendar

16 April 1999

Product speciﬁcation

1. General description

The PCF8563 is a CMOS real-time clock/calendar optimized for low power

consumption. A programmable clock output, interrupt output and voltage-low detector

are also provided. All address and data are transferred serially via a two-line

bidirectional I²C-bus. Maximum bus speed is 400 kbits/s. The built-in word address

2. Features

■ Provides year, month, day, weekday, hours, minutes and seconds based on

32.768 kHz quartz crystal

■ Century ﬂag

■ Wide operating supply voltage range: 1.0 to 5.5 V

■ Low back-up current; typical 0.25 µA at V_DD= 3.0 V and T_amb= 25 °C

■ 400 kHz two-wire I²C-bus interface (at V_DD= 1.8 to 5.5 V)

■ Programmable clock output for peripheral devices: 32.768 kHz, 1024 Hz,

32 Hz and 1 Hz

■ Alarm and timer functions

■ Voltage-low detector

■ Integrated oscillator capacitor

■ Internal power-on reset

■ I²C-bus slave address: read A3H; write A2H

■ Open drain interrupt pin.
