1 / 19 page 1 ® FN6690.1 ISL12008 I2C Real Time Clock with Battery Backup Low Power RTC with Battery ReSeal™ Function 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. 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.
