Description

RV-3049-C2 is a CMOS low power, real-time clock/calendar module with built-in Thermometer and Digital Temperature Compensation circuitry (DTCXO). The temperature compensation circuitry is factory-calibrated and greatly improves the time accuracy by compensating the frequency-deviation @ 25°C and the anticipated frequency-drift over the temperature of the embedded 32.768 kHz “Tuning-Fork” crystal, even over the extended Temperature Range -40°C to +125°C. Data is transferred serially via a SPI interface with a maximum SCL clock frequency in fast mode of 1 MHz, the built-in word address register is incremented automatically after each written or read data byte. Beyond standard RTC-functions like year, month, day, weekday, hours, minutes, seconds information, the RV-3049-C2 offers highly versatile Alarm and Timer-Interrupt function, programmable Clock-Output and Low-Voltage Detector. RTC module with built-in “Tuning Fork” crystal oscillating at 32.768 kHz Factory calibrated, all built-in Temperature Compensation circuitry SPI serial interface with fast mode SCL clock frequency of 1 MHz Provides year, month, day, weekday, hours, minutes and seconds Main Power Supply to Backup Battery switchover circuitry with Trickle Charger AEC-Q200 qualified The unique features make this product perfectly suitable for many applications: Automotive: Car Radio / GPS and Tracking Systems / Dashboard / Engine Controller / Car Mobile & Entertainment Systems / Tachometers Metering: E-meter / Heating Counter Outdoor: ATM & POS systems / Surveillance & Safety systems / Ticketing system All kind of portable and battery operated devices Industrial and consumer electronics White goods
