ISL12082
I2C-Bus
Real Time Clock with Two Interrupts, Alarm, and Timer
Low Power RTC with Battery ReSeal,
2 IRQs, Hundredths of a Second Time,
and Crystal Compensation
The ISL12082 device is a low power real time clock with
timing and crystal compensation, clock/calendar, power fail
indicator, 2 IRQs, periodic or polled alarm, timer/watchdog,
and intelligent battery backup switching.
The oscillator uses an external, low-cost 32.768kHz crystal.
The real time clock tracks time with separate registers for
hours, minutes, seconds and hundredths of a second. 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.
