Data Sheet

FN6371.1

Real-Time Clock/Calendar with EEPROM

Features

The ISL12025 device is a low power real-time clock with

timing and crystal compensation, clock/calender, 64-bit

unique ID, power-fail indicator, two periodic or polled alarms,

intelligent battery backup switching, CPU Supervisor and

integrated 512 x 8-bit EEPROM, in a 16 Bytes per page

format.

• Real-Time Clock/Calendar

- Tracks Time in Hours, Minutes, and Seconds

- Day of the Week, Day, Month, and Year

• 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
