    Rev 1.00
    August 7, 2015 Low Power RTC with 8 Bytes of Battery Backed SRAM and Separate FOUT
    The ISL1220 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, battery-backed user SRAM and separate FOUT
    and IRQ outputs.
    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. Ordering Information
