Data Sheet  
FN6371.1  
Real-Time Clock/Calendar with EEPROM  
Features  
The ISL12025 device is a low power real-time clock with  
timing and crystal compensation, clock/calender, 64-bit  
unique ID, power-fail indicator, two periodic or polled alarms,  
intelligent battery backup switching, CPU Supervisor and  
integrated 512 x 8-bit EEPROM, in a 16 Bytes per page  
format.  
• Real-Time Clock/Calendar  
- Tracks Time in Hours, Minutes, and Seconds  
- Day of the Week, Day, Month, and Year  
• 64-bit Unique ID  
• 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  
• On-Chip Oscillator Compensation  
- Internal Feedback Resistor and Compensation

NOTE: Intersil Pb-free plus anneal products employ special Pb-free  
material sets; molding compounds/die attach materials and 100% matte  
tin plate termination finish, which are RoHS compliant and compatible  
with both SnPb and Pb-free soldering operations. Intersil Pb-free  
products are MSL classified at Pb-free peak reflow temperatures that  
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
