Low Power RTC with Battery Backed SRAM, Integrated  
±5ppm Temperature Compensation and Auto Daylight  
Saving  
ISL12022M  
Features  
The ISL12022M device is a low power real time clock (RTC) with  
an embedded temperature sensor and crystal. Device functions  
include oscillator compensation, clock/calendar, power fail and  
low battery monitors, brownout indicator, one-time, periodic or  
polled alarms, intelligent battery backup switching, Battery  
Reseal™ function and 128 bytes of battery-backed user SRAM.  
Backup battery current draw is less than 1.6µA over the  
temperature range. The device is offered in a 20 Ld SOIC module  
that contains the RTC and an embedded 32.768kHz quartz  
crystal. The calibrated oscillator provides less than ±5ppm drift  
over the full -40°C to +85°C temperature range.  
• Embedded 32.768kHz Quartz Crystal in the Package  
• 20 Ld SOIC Package (for DFN version, refer to the ISL12020M)  
• Calendar  
• On-chip Oscillator Temperature Compensation  
• 10-bit Digital Temperature Sensor Output  
• 15 Selectable Frequency Outputs  
• Interrupt for Alarm or 15 Selectable Frequency Outputs  
• Automatic Backup to Battery or Supercapacitor  
• V and Battery Status Monitors  
DD  
The RTC tracks time with separate registers for hours, minutes,  
and seconds. The calendar registers track date, month, year and  
day of the week and are accurate through 2099, with automatic  
leap year correction.  
• Battery Reseal™ Function to Extend Battery Shelf Life  
• Power Status Brownout Monitor  
• Time Stamp for Battery Switchover  
• 128 Bytes Battery-Backed User SRAM  
• 1.6µA Max Battery Current  
Daylight Savings time adjustment is done automatically, using  
parameters entered by the user. Power fail and battery monitors  
offer user-selectable trip levels. The time stamp function records
