RV-8063-C7 Real Time Clock Module with SPI 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 High Speed SPI Interface 7 MHz Programmable Offset Register Alarm and Timer Interrupt Minute and Half Minute Interrupt Oscillator Stop Detection Programmable Clock Output Time keeping mode down to 0.9 V Very low power consumption 190nA All dimensions in mm typical DESCRIPTION: This ultra small RTC Module with a 3-wire SPI-bus 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 programmable Offset Register value allows aging compensation. The calendar function tracks Weekdays, Date, Month and Years with automatic Leap Year calculation. The clock function provides, Seconds, Minutes and Hours in AM/PM or 24h format. Programmable Alarm, Timer, Interrupt and CLKOUT frequency settings increase flexibility using this device. The typical current consumption @ VDD = 3 V is only 190 nA. 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: VDD VSS SCL SDIO CE 5 2 POWER CONTROL 7 1 8 SPI-BUS INTERFACE FREQUENCY OFFSET COMPENSATION XTAL OSC CLKOUT CLKOE 6 3 4 INPUT OUTPUT CONTROL INT RESET DIVIDER SYSTEM CONTROL LOGIC Control1 Control2 Offset RAM Seconds Minutes Hours Date Weekdays Months Years Seconds Alarm Minutes Alarm Hours Alarm Date Alarm Weekday Alarm Timer Value Timer Mode 00 11 ELECTRICAL CHARACTERISTICS AT 25°C: Symbol Condition Supply voltage VDD SPI Bus Active 1.8 Supply voltage VDD Time keeping 0.9 Current consumption during access IDD Current consumption Time keeping mode IDDO Min.
