    Rev 2.00
    Sep 25, 2015 Low Cost and Low Power I2C RTC Real Time Clock/Calendar with Alarm Function
    and Dual IRQ Pins
    The ISL12057 device is a low-power, real-time clock that is
    pin compatible and functionally equivalent to Maxim DS1337
    with clock/calendar and alarm function.
    The oscillator uses an external, low-cost 32.768kHz crystal
    with 6pF load capacitance. 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. Pinouts Features Pin Compatible to Maxim DS1337 Functionally Equivalent to Maxim DS1337 Real-Time Clock/Calendar
