FN6757.0
Low Power and Low Cost RTC
The ISL12059 device is a low power real time clock with
clock/calendar, and 512Hz/digital output function.
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.
