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 register is incremented automatically after each written or read data byte.

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.

Applications

• Mobile telephones
• Portable instruments
• Fax machines
• Battery powered products.
