Low Power RTC with Battery Backed SRAM,  
Integrated ±5ppm Temperature Compensation and  
Auto Daylight Saving  
ISL12022M  
Features  
• Embedded 32.768kHz Quartz Crystal in the Package  
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.  
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.  
• 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  
• VDD and Battery Status Monitors  
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  
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 the time and date of
