ISL1219

Real Time Clock/Calendar with Event Detection

Low Power RTC with Battery Backed

SRAM and Event Detection

The ISL1219 device is a low power real time clock with

Event Detect and Time Stamp function, timing and crystal

compensation, clock/calendar, power fail indicator, periodic

or polled alarm, intelligent battery backup switching and 2

Bytes of battery-backed user SRAM.

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.
