The calendar function tracks year, month, date, and day-of-the-week with built-in century and leap-year flags. The clock function tracks minute and second in 24-hour format. Programmable alarm setting and universal timer functions increase flexibility. For pick-and-place equipment, the parts are available in 12 mm tape: 7” (178 mm) reel with 1'000 parts 10” (254 mm) reel with 2'500 parts 13” (330 mm) reel with 5'000 parts BLOCK DIAGRAM: VDD 32.768 KHz CRYSTAL Voltage Detector 1 GND Control 1 OSC DIVIDER CLKOUT 2 CLKOE 00 Control 2 6 Seconds Minutes OUTPUT CONTROL Hours Days 10 Weekdays INT 7 Month / Century CONTROL LOGIC SCL 4 Years Minutes Alarm 2 I C-BUS Hour Alarm INTERFACE Day Alarm SDA Weekday Alarm 5 ADDRESS REGISTER CLKOUT frequency Timer Control Timer 0F POR * The I2C Bus is a trademark of Philips Electronics N.V.
