® ISL12030 Real Time Clock with 50/60 Hz Clock and Alarms Data Sheet December 14, 2007 FN6617.0 Low Power RTC with 50/60 Cycle AC Input, Alarms and Daylight Savings Correction www.datasheet4u.com The ISL12030 device is a low power real time clock with 50/60 AC input for timing synchronization, clock/calendar registers, single periodic or polled alarms. There are 128 bytes of user SRAM. The oscillator uses a 50/60 cycle sine wave input. The real time clock tracks time with separate registers for hours, minutes, and seconds. The calendar registers contain the date, month, year, and day of the week. The calendar is accurate through year 2100, with automatic leap year correction and auto daylight savings correction.
