This RTC has an I2C Bus (2-wire SerialInterface) and offers temperature compensated time. The STC-Smart Temperature Compensation is calibrated in the factory and leads to a very high time-accuracy of ± 6ppm from -40°C to +85°C and ± 8ppm from -40°C to +125°C. Beside standard RTC functions, it includes a Backup-Battery Input with internal switchover function, a programmable Trickle-charge circuitry, an integrated Temperature Sensor with digital-output and offers 8 Bytes RAM and 2 Bytes EEPROM for customer's application. The calendar function tracks year and leap -year flags. The clock tracks second, minute and hour in 24-hour format. Programmable alarm setting and universal timer functions increase flexibility. For pick-and-place equipment, the parts are available in 12 mm tape: 7” (178 mm) reel with 1'000 parts 7” (178 mm) reel with 3'000 parts ELECTRICAL CHARACTERISTICS AT 25°C: Symbol Condition VDD Time keeping 1.3 Supply voltage VDD Temp. comp. 1.8 5.5 V Current consumption IDDO VDD = 3V 800 1000 nA Progr. 32.768/1024/32/1 Hz ±10 ppm Supply voltage CLKOUT frequency F/F @ 25°C Freq.vs.Temp.
