ISL12024
Real-Time Clock/Calendar with Embedded
Unique ID
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.
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.
