The ISL12026IBZ is a Real-time Clock/Calendar with I²C Bus™ and EEPROM. The ISL12026 devices are micro power real time clocks with timing and crystal compensation, clock/calendar, power-fail indicator, two periodic or polled alarms, intelligent battery backup switching and integrated 512x8-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.
