The RV-3029-C3 is an ultra miniature Real-Time-Clock Module 2 2 I C Interface with embedded Crystal. This RTC has an I C Bus (2-wire Serial- Temperature Compensation Interface) and offers temperature compensated time. The STC-Smart Automotive qualified, according to Temperature Compensation is calibrated in the factory and leads AEC-Q200 Rev. C to a very high time-accuracy of 6ppm from -40C to +85C and 8ppm from -40C to +125C. Option A: Calibrated Beside standard RTC functions, it includes a Backup-Battery Input with Temperature Time Deviation internal switchover function, a programmable Trickle-charge circuitry, +25C 0.26 s/day 3ppm an integrated Temperature Sensor with digital-output and offers 8 Bytes 0C to +50C 0.35 s/day 4ppm RAM and 2 Bytes EEPROM for customer s application. -10C to +60C 0.44 s/day 5ppm -40C to +85C 0.52 s/day 6ppm The calendar function tracks year and leap -year ags. The clock tracks -40C to +125C 0.70 s/day 8ppm second, minute and hour in 24-hour format. Programmable alarm setting Option B: Default and universal timer functions increase exibility.
