Real-time clock module RV-3049-C3

RV-3149-C3 is Form Fit and Function compatible.The package features now side castellations post soldering for optical inspection. RV-3049-C3 is an high accuracy, ultra low power Real-Time-Clock Module with embedded 32.768 kHz Crystal. High accuracy, high stability is achieved by factory calibrated, temperature compensated DTCXO and results to time-accuracy of ± 3.0 ppm accross the temperature range from -40°C to +85°C. Standard Clock & Calendar function tracks second, minute, hour in 24-hour format, year and leap -year fl ags. Beside standard RTC function like Timer & Alarm, it includes integrated Temperature Sensor, Time Stamp Event Input and User RAM and offers I²C-bus (2-wire Interface). RV-8803-C7 is the smallest and offers the lowest current consumption among all temperature compensated RTC modules. 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 All kind of portable and battery operated devices Industrial and consumer electronics White goods
