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