Real Time Clock/Calendar

Data Sheet

July 29, 2005

FN8085.3

Low Power RTC with Battery Backed

SRAM

The ISL1208 device is a low power real time clock with

timing and crystal compensation, clock/calendar, power fail

indicator, periodic or polled alarm, intelligent battery backup

switching and 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.
