Low Power RTC with Battery Backed  
SRAM  
Features  
• Real Time Clock/Calendar  
- Tracks Time in Hours, Minutes, and Seconds  
- Day of the Week, Day, Month, and Year  
The ISL1208 device is a low power real time clock with  
timing and crystal compensation, clock/calendar, power fail  
indicator, periodic or polled alarm, intelligent battery backup  
switching and battery-backed user SRAM.  
• 15 Selectable Frequency Outputs  
• Single Alarm  
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 to the Second, Minute, Hour, Day of the Week,  
Day, or Month  
- Single Event or Pulse Interrupt Mode  
• Automatic Backup to Battery or Super Cap  
• Power Failure Detection
