Low Power RTC with Battery-Backed SRAM and Embedded Temp Compensation  
±5ppm with Auto Daylight Saving  
The ISL12022 device is a low power real time clock with an  
Features  
embedded Temp sensor for oscillator compensation,  
• Real Time Clock/Calendar  
- Tracks Time in Hours, Minutes and Seconds  
- Day of the Week, Day, Month, and Year  
clock/calendar, power fail, low battery monitor, brownout  
indicator, single periodic or polled alarms, intelligent  
battery-backup switching, Battery Reseal™ function, and  
128 bytes of battery-backed user SRAM.  
• On-chip Oscillator Compensation Over the Operating  
Temperature Range  
- ±5ppm Over -40°C to +85°C  
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.  
• 10-bit Digital Temperature Sensor Output  
- ±2°C Accuracy  
• Customer Programmable Day Light Saving Time  
• 15 Selectable Frequency Outputs  
Daylight Savings time adjustment is done automatically, using  
parameters entered by the user. Power fail and battery  
monitors offer user-selectable trip levels. A time stamp
