概览

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.
