    Rev 2.00
    July 15, 2010 Low Power RTC with Battery Backed SRAM and Event Detection
    The ISL1219 device is a low power real time clock with
    Event Detect and Time Stamp function, timing and crystal
    compensation, clock/calendar, power fail indicator, periodic
    or polled alarm, intelligent battery backup switching and 2
    Bytes of 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. Ordering Information
