RV-3049-C2 Real Time Clock Module with SPI-Bus MICRO CRYSTAL SWITZERLAND DIMENSIONS Package: Recommended Solder Pad: 1,0 1,0 1,0 1,0 5,0 0,2 0,6 1,0 0,4 4,6 100% leadfree, RoHS - compliant All dimensions in mm typical DESCRIPTION: Extremely Accurate RTC Module with embedded Xtal. The RV-3049-C2 is a Real-Time-Clock Module with embedded SPI Interface Crystal. This RTC has 4-wire serial Interface (SPI-Bus) Temperature Compensation 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.
