This RTC has a 4-wire Serial-Interface (SPI-Bus) 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 -40C to +85C and 8ppm from -40C to +125C. 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 10" (254 mm) reel with 2'500 parts 13" (330 mm) reel with 5'000 parts 32.768 KHz CRYSTAL ar y OSC CLKOUT CLKOE INT OUTPUT CONTROL DIVIDER and TEMPERATURE COMPENSATION LOGIC VDD VBACKUP VSS POWER CONTROL SYSTEM CONTROL LOGIC CE CLK SDI SDO SPI-BUS 4-wire INTERFACE TEMPERATURE SENSOR Control 1 Control 2 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 Xtal Compensation User RAM 4 Byte User RAM Control 3 Xtal Offset T0 Temperature Temp Coefficient 0,9 2,2 4,0 00 Pr el im in 20 23 31 Version 0.3/02.2008 ELECTRICAL CHARACTERISTICS AT 25C: Symbol Supply voltage Supply voltage Current consumption CLKOUT frequency Frequency Tolerance Aging first year max.
