Sep 25, 2015
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.
