ISL12027, ISL12027A  
Real Time Clock/Calendar with EEPROM  
FN8232  
Rev 9.00  
September 23, 2015  
The ISL12027 device is a low power real time clock with  
timing and crystal compensation, clock/calender, power-fail  
indicator, two periodic or polled alarms, intelligent battery  
backup switching, CPU Supervisor and integrated 512x8-bit  
EEPROM, in 16 Byte per page format.  
Features  
• Real Time Clock/Calendar  
- Tracks Time in Hours, Minutes and Seconds  
- Day of the Week, Day, Month and Year  
• Two Non-Volatile Alarms  
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.  
- Settable on the Second, Minute, Hour, Day of the Week,  
Day, or Month  
- Repeat Mode (Periodic Interrupts)  
• Automatic Backup to Battery or SuperCap  
• On-Chip Oscillator Compensation  
The ISL12027 and ISL12027A Power Control Settings are  
different. The ISL12027 uses the Legacy Mode Setting, and  
the ISL12027A uses the Standard Mode Setting.  
- Internal Feedback Resistor and Compensation  
Capacitors  
- 64 Position Digitally Controlled Trim Capacitor  
Applications that have V

- 6 Digital Frequency Adjustment Settings to ±30ppm  
ISL12027A. Please refer to“Power Control Operation” on  
page 15 for more details. Also, please refer to “I2C  
Communications During Battery Backup and LVR Operation”  
on page 24 for important details.  
• 512x8-Bits of EEPROM
