Low Power RTC with Battery ReSeal

Function

Features

• Pin Compatible to ST M41T00S and Maxim DS1340

The ISL12008 device is a low power real time clock/calendar

that is pin compatible and functionally equivalent to the

ST M41T00S and Maxim DS1340 with timing and crystal

compensation. The device additionally provides power-fail

indicator, software alarm and intelligent battery backup.

• Functionality Equivalent to ST M41T00S and Maxim

DS1340

• Real Time Clock/Calendar

- Tracks Time in Hours, Minutes, Seconds and

Sub-seconds

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.

- Day of the Week, Day, Month, and Year

• 512Hz Frequency Outputs for On-Chip Crystal

Compensation

• Software Alarm

- Settable to the Second, Minute, Hour, Day of the Week,

Day, or Month
