Real Time Clock Module with SPI-Bus DIMENSIONS Package: 100% leadfree, RoHS - compliant Extremely Accurate RTC Module with embedded Xtal. SPI Interface Temperature Compensation Automotive qualified, according to AEC-Q200 Rev. C Option A: Temperature Time Deviation @ +25°C ± 0.26 s/day 0°C to +50°C ± 0.35 s/day -10°C to +60°C ± 0.44 s/day -40°C to +85°C ± 0.52 s/day -40°C to +125°C ± 0.70 s/day DESCRIPTION: The RV-3049-C3 is an ultra miniature Real-Time-Clock Module with embedded Crystal. This RTC has an SPI Bus (4-wire SerialInterface) and offers temperature compensated time. The STC-Smart Temperature Compensation is calibrated in the factory and leads to a very high time-accuracy of ± 6ppm from -40°C to +85°C and ± 8ppm from -40°C to +125°C. Beside standard RTC functions, it includes a Backup-Battery Input with internal switchover function, a programmable Trickle-charge circuitry, an integrated Temperature Sensor with digital-output and offers 8 Bytes RAM and 2 Bytes EEPROM for customer's application. The calendar function tracks year and leap -year ags. The clock tracks second, minute and hour in 24-hour format. Programmable alarm setting and universal timer functions increase exibility. 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 BLOCKDIAGRAM: 32.768 kHz Xtal DIVIDER and TEMPERATURE COMPENSATION LOGIC OUTPUT CONTROL SYSTEM CONTROL LOGIC SPI-BUS 4-wire Serial Interface TEMPERATURE SENSOR On / Off Ctrl IRQ Ctrl Control 3 Control 4 Seconds Minutes Hours Date Weekday Month Year Seconds Alarm Minutes Alarm Hour Alarm Day Alarm Weekday Alarm Month Alarm Year Alarm Timer Low Timer High Temperature °K User EEPROM 2 Bytes EE Control 1 Xtal Deviation Xtal Temp-Coef Xtal T0 Temp User RAM 8 Byte User RAM
