RV-2123-C2 Real Time Clock Module with SPI Bus DIMENSIONS Package: Recommended Solder Pad: 1,0 1,0 1,0 1,0 0,2 5,0 0,6 1,0 0,4 4,6 100% leadfree, RoHS - compliant All dimensions in mm typical DESCRIPTION: Ultra low power consumption 130nA Automotive qualified, according to This RTC IC has been specially designed to achieve an ultra-low power AEC-Q200 Rev. C consumption of typically 130nA V 3.0V in time-keeping mode. DD Xtal integrated solution. The very small SMT ceramic-package combines the 32.768 kHz crystal Frequency-Offset Trimming Register unit with the CMOS-based oscillator and real-time-clock circuitry. Miniature SMT ceramic package The calendar function tracks year, month, date, and day-of-the-week with Very tight frequency tolerance built-in century and leap-year ags. The clock function tracks minute and SPI Bus Interface (SCL up to 8 MHz) second in 24-hour format. Programmable alarm setting and universal Programmable Clock-output timer functions increase exibility. Low aging For pick-and-place equipment, the parts are available in 12 mm tape: Time keeping mode down to 1.1 V 7 (178 mm) reel with 1 000 parts Programmable alarm, timer and 13 (330 mm) reel with 5 000 parts interrupt functions BLOCK DIAGRAM: DIVIDER OFFS E T FUNCTION and OSCILLATOR FREQUENCY-OFFSET 0D OFFSET 32 .768 kH z COMPENSATION MONITOR TIM E R FU N C TION 0E Timer / CLKOUT Control CLKOUT CLOCK 2 0F Countdown Tim er OUTPUT CLKOE 10 CONTROL 00 C ontrol / S tatus 1 IN T 8 INTERRUPT 01 C ontrol / S tatus 2 TIME VDD POWER-ON OS / Seconds 1 02 R E SET V SS 03 VL / M inutes 6 04 Hours 05 Days W A TCH DOG 06 Weekdays 07 Months 08 Years CE 7 SCL SPI 4w ire 3 A LA R M FUNCTION SDI IN TE R FA C E 09 Minute 4 0A Hour SDO 5 0B Day 0C Weekday 0,6 3,2 0,2 max.1,2 0,35 0,9 2,2 0,9 4,0ELECTRICAL CHARACTERISTICS Symbol Condition Min.
