This RTC has an SPI Bus (4-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 BLOCKDIAGRAM: 32.768 kHz Xtal DIVIDER and TEMPERATURE COMPENSATION LOGIC OSC CLKOUT CLKOE INT VDD VBACKUP VSS CE SCL SDO SDI 3 1 OUTPUT CONTROL 7 2 POWER CONTROL 9 SYSTEM CONTROL LOGIC 6 8 4 5 10 SPI-BUS 4-wire Serial Interface TEMPERATURE SENSOR On / Off Ctrl IRQ Ctrl Control 3 Control 4 Seconds Minutes Hours Date Weekday Month Year Seconds Alarm Minutes Alarm Hour Alarm Day Alarm Weekday Alarm Month Alarm Year Alarm Timer Low Timer High Temperature °K User EEPROM 2 Bytes EE Control 1 Xtal Deviation Xtal Temp-Coef Xtal T0 Temp User RAM 8 Byte User RAM 00 20 28 29 38 3F 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.
