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.
