Programmable alarm, timer and interrupt Low power consumption, low ageing Available on T&R - 1k or 5k pcs per reel Evaluation / development board & manual available on request The I2C-Bus is a trademark of Philips Electronics NV Block Diagram 32.768kHz CRYSTAL OSC VOLTAGE DETECTOR DIVIDER CLKOUT CLKOE OUTPUT CONTROL / INT SCL CONTROL LOGIC I2C BUS INTERFACE SDA PDR ADDRESS REGISTER Control 1 00 Control 2 Seconds Minutes Hours Days Weekdays Month / Century Years Minutes Alarm Hour Alarm Day Alarm Weekday Alarm CLKOUT Frequency Timer Control 0F Timer Description This very small SMD ceramic package has been specially designed to combine the 32.768kHz crystal unit with the CMOS based oscillator and real-time clock circuit. The calendar function tracks year, month, date and day of the week with built-in century and leap-year flags. The clock function tracks minutes and seconds in 24-hour format. Programmable alarm setting and universal timer functions increase flexibility.
