Real-time clock module RV-3029-C3

RV-3129-C3 is Form Fit and Function compatible.The package features now side castellations post soldering for optical inspection. RV-3029-C3 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 an I²C interface with a maximum SCL clock frequency in fast mode of 400 kHz, 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-3029-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 I²C serial interface with fast mode SCL clock frequency of 400 kHz Provides year, month, day, weekday, hours, minutes and seconds Main Power Supply to Backup Battery switchover circuitry with Trickle Charger 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
