Real-Time Clock/Calendar with Embedded
Unique ID
Features
• Real-Time Clock/Calendar
The ISL12024 device is a micro-power real-time clock with
embedded 64-bit unique ID, timing and crystal
compensation, clock/calender, power-fail indicator, two
periodic or polled alarms, intelligent battery backup
switching, and integrated 512 x 8-bit EEPROM configured in
16 Bytes per page.
- Tracks Time in Hours, Minutes, and Seconds
- Day of the Week, Day, Month, and Year
- 3 Selectable Frequency Outputs
• 64-bit Unique ID
• Two Non-Volatile Alarms
- Settable on the Second, Minute, Hour, Day of the Week,
Day, or Month
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.
- Repeat Mode (periodic interrupts)
• Automatic Backup to Battery or SuperCap
• On-Chip Oscillator Compensation
- Internal Feedback Resistor and Compensation
Capacitors
Ordering Information
- 64 Position Digitally Controlled Trim Capacitor
- 6 Digital Frequency Adjustment Settings to ±30ppm

- Endurance: 2,000,000 Cycles Per Byte
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
