    Jun 22, 2006 Low Power RTC with Battery Backed SRAM
    The ISL1218 device is a low power real time clock with
    timing and crystal compensation, clock/calendar, power fail
    indicator, periodic or polled alarm, intelligent battery backup
    switching and battery-backed user SRAM.
    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. Real Time Clock/Calendar
    -Tracks Time in Hours, Minutes, and Seconds
