GENERAL DESCRIPTION
The PCF8573 is a low threshold, CMOS circuit that functions as a real time clock/calendar. Addresses and data are transferred serially via the two-line bidirectional I2C-bus.
FEATURES
• Serial input/output I2C-bus interface for minutes, hours, days and months
• Additional pulse outputs for seconds and minutes
• Alarm register for presetting a time for alarm or remote switching functions
• On-chip power fail detector
• Separate ground pin for the clock allows easy implementation of battery back-up during supply interruption
• Crystal oscillator control (32.768 kHz)
• Low power consumption.
