ISL12027 General Description

The ISL12027 device is a low power real time clock with timing and crystal compensation, clock/calender, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching, CPU Supervisor and integrated 512 x 8 bit EEPROM, in 16 Byte per page format.

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.
