ISL12030
Real Time Clock with 50/60 Hz Clock and Alarms
Low Power RTC with 50/60 Cycle AC
Input, Alarms and Daylight Savings
Correction
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.
