PCF8563

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

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

2.
