This RTC IC has been specially designed to achieve an ultra-low power Frequency-Offset Trimming Register consumption of typically 130nA V 3.0V in time-keeping mode. DD Backup supply switchover circuitry The very small SMT ceramic-package combines the 32.768 kHz crystal Miniature SMT ceramic package unit with the CMOS-based oscillator and real-time-clock circuitry. Very tight frequency tolerance The calendar function tracks year, month, date, and day-of-the-week 2 I C Bus Interface (fast mode 1 MHz) with built-in century and leap-year ags. The clock function tracks minute Programmable Clock-output and second in 24-hour format. Programmable alarm setting, dual timer Low aging functions and integrated switch-over circuitry to backup supply voltage Time keeping mode down to 1.2 V increase exibility. Programmable alarm, timer and For pick-and-place equipment, the parts are available in 12 mm tape: interrupt functions 7 (178 mm) reel with 1 000 or 3 000 parts 13 (330 mm) reel with 10 000 parts BLOCK DIAGRAM: 32.768 kHz Xtal Control 0 00 FREQUENCY Control 1 OSC DIVIDER Control 2 and Seconds 5 OFFSET Minutes CLKOUT CLKOUT COMPENSATION Hours 2 & Days INT 1 Interrupt Weekdays 6 CONTROL Months INT 2 Years Minute Alarm 1 Hour Alarm V DD Day Alarm Weekday Alarm SYSTEM 8 Frequency Offset V CONTROL BACKUP POWER Timer & CLKOUT CONTROL LOGIC Timer A Clock 7 V Timer A SS Timer B Clock Timer B 13 2 I C-BUS 3 SCL 2-wire 4 Serial SDA Interface 2,502,50 max.0,9max.0,9 0,10,1 00,6,6 00,8,8 11,4,4 0,80,8 33,0,0ELECTRICAL CHARACTERISTICS Symbol Condition Min.
