RV-4162-C7 Real Time Clock Module with I2C Bus DIMENSIONS Package: Recommended Solder Pad: 100% leadfree, RoHS - compliant Ultra small SMT ceramic package with integrated 32.768kHz Crystal Automotive qualified, according to AEC-Q200 Rev. C I2C Interface Address: D0h Frequency-Offset Trimming Register Programmable Alarm and Interrupt Oscillator Fail Detection Watchdog Timer Programmable Clock-Output Time keeping mode down to 1.0 V All dimensions in mm typical DESCRIPTION: This ultra small RTC Module has been specially designed for miniature and cost sensitive high volume applications. The very small SMT ceramic package combines the 32.768 kHz crystal unit with the CMOS-based oscillator and real-time-clock circuitry. The clock function provides tenths/hundredths of seconds, seconds, minutes and hours. The calendar function tracks date, month, year and century with automatic leap year compensation. Programmable CLKOUT frequencies, alarm settings and watchdog function increase flexibility using this device. For pick-and-place equipment, the parts are available in 12 mm tape: 7” (178 mm) reel with 1'000 parts 7” (178 mm) reel with 3'000 parts BLOCK DIAGRAM: 32.768 KHz CRYSTAL OSC CLKOUT 2 th th DIVIDER 10 /100 Second FREQUENCY-OFFSET COMPENSATION CLKOUT OUTPUT CONTROL OSCILLATOR FAIL DETECTION Seconds 00 Minutes Hours Day Date Month / Century INT SCL SDA INT CONTROL 6 Years Freq.
