| RV-8564-C2 DIMENSIONS Package: 5,0 0,2 1,0 0,4 1,0 1,0 Real Time Clock Module with I2C Bus Recommended Solder Pad: 1,0 0,6 0,9 1,0 0,2 0,35 3,2 4,6 0,6 100% leadfree, RoHS - compliant max.1,2 All dimensions in mm typical Xtal integrated solution Miniature SMT ceramic package Ultra low power consumption Very tight frequency tolerance I2C Bus Interface (400 kHz) * Programmable Clock-output Low aging Time keeping mode down to 1.2 V Programmable alarm, timer and interrupt functions DESCRIPTION: This very small SMD ceramic package has been specially designed to combine the 32.768 kHz 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 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 GND 6 DIVIDER CLKOUT 2 CLKOE 10 INT 7 CONTROL LOGIC SCL 4 I C-BUS INTERFACE SDA 5 ADDRESS REGISTER 2 32.768 KHz CRYSTAL 1 OSC Voltage Detector Control 1 Control 2 Seconds Minutes Hours Days Weekdays Month / Century Years Minutes Alarm Hour Alarm Day Alarm Weekday Alarm CLKOUT frequency Timer Control Timer POR 0F 00 OUTPUT CONTROL * The I2C Bus is a trademark of Philips Electronics N.V.
