Real Time Clock/Calendar with EEPROM  
Features  
The ISL12029 device is a low power real time clock with  
clock/calender, power-fail indicator, clock output and crystal  
compensation, two periodic or polled alarms (open drain  
output), intelligent battery backup switching, CPU  
Supervisor, integrated 512 x 8 bit EEPROM configured in 16  
byte per page.  
• Real Time Clock/Calendar  
- Tracks Time in Hours, Minutes, and Seconds  
- Day of the Week, Day, Month, and Year  
- 3 Selectable Frequency Outputs  
• Two Non-Volatile Alarms  
- Settable on the Second, Minute, Hour, Day of the Week,  
Day, or Month  
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.  
- Repeat Mode (periodic interrupts)  
• Automatic Backup to Battery or SuperCap  
- Power Failure Detection  
- 800nA Battery Supply Current  
• On-Chip Oscillator Compensation:
