FN8231.9  
Real Time Clock/Calendar with I2C Bus™  
and EEPROM  
Features  
• Real Time Clock/Calendar  
The ISL12026 and the ISL12026A devices are micro power  
real time clocks with timing and crystal compensation,  
clock/calender, power-fail indicator, two periodic or polled  
alarms, intelligent battery backup switching, and integrated  
512x8-bit EEPROM configured in 16 Bytes per page.  
- 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  
• On-Chip Oscillator Compensation  
- Internal Feedback Resistor and Compensation  
Capacitors  
The ISL12026 and ISL12026A have different types of Power  
Control Settings. The ISL12026 uses the Legacy Mode  
Setting, which follows conditions set in X1226 products. The  
ISL12026A uses the Standard Mode Setting. Please refer to  
“Power Control Operation” on page 13 for more details. Also,  
please refer to “I2C Communications During Battery Backup”  
on page 22 for important details.  
- 64 Position Digitally Controlled Trim Capacitor  
- 6 Digital Frequency Adjustment Settings to ±30ppm  
• 512x8 Bits of EEPROM  
- 16-Byte Page Write Mode (32 total pages)  
- 8 Modes of BlockLock™ Protection  
- Single Byte Write Capability  
• High Reliability  
Pinouts  
- Data Retention: 50 years  
- Endurance: >2,000,000 Cycles Per Byte
