Category:
Timming Circuits
-> Real Time Clocks
Description: Real Time Clock/Calendar with EEPROM<<<>>>The ISL12028 device is a low power real time clock with clock/calender, power-fail indicator, clock output and crystal compensation, two periodic or polled alarms (CMOS output), intelligent battery backup switching, CPU Supervisor, integrated 512 x 8 bit EEPROM configured in 16 Byte per page.<<<>>><<<>>>The oscillator uses an external, low-cost 32.768kHz crystal. The real time clock tracks time with separate registers for hours, minutes, and seconds. The device has calendar registers for date, month, year and day of the week. The calendar is accurate through 2099, with automatic leap year correction.<<<>>> <<<>>> Key Features<<<>>> <<<>>><<<>>> * Real Time Clock/Calendar<<<>>> o Tracks time in Hours, Minutes, and Seconds<<<>>> o Day of the Week, Day, Month, and Year<<<>>> o 3 Selectable Frequency Outputs <<<>>> * Two Non-Volatile Alarms<<<>>> o Settable on the Second, Minute, Hour, Day of the Week, Day, or Month<<<>>> o Repeat Mode (periodic interrupts) <<<>>> * Automatic Backup to Battery or SuperCap<<<>>> o Power Failure Detection<<<>>> o 800nA Battery Supply Current <<<>>> * On-Chip Oscillator Compensation<<<>>> o Internal Feedback Resistor and Compensation Capacitors<<<>>> o 64 Position Digitally Controlled Trim Capacitor<<<>>> o 6 Digital Frequency Adjustment Settings to ±30ppm <<<>>> * 512 x 8 Bits of EEPROM:<<<>>> o 16-Byte Page Write Mode (32 total pages)<<<>>> o 8 modes of Block Lock™ Protection<<<>>> o Single Byte Write Capability<<<>>> o Data Retention: 50 years<<<>>> o Endurance: >2,000,000 Cycles Per Byte <<<>>> * CPU Supervisor Functions:<<<>>> o Power On Reset, Low Voltage Sense<<<>>> o Watchdog Timer (0.25, 0.75, 1.75 sec) <<<>>> * I2C* Interface - 400kHz data transfer rate<<<>>> * 14 Ld SOIC and TSSOP Packages<<<>>> * Pb-Free Plus Anneal Available (RoHS Compliant)
