ISL1208
I2C Real Time Clock/Calendar
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.
