Features
• 50/60 Cycle AC as a Primary Clock Input for RTC Timing
• Real Time Clock/Calendar
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.
- Tracks Time in Hours, Minutes, Seconds and tenths of a
Second
- Day of the Week, Day, Month and Year
• Auto Daylight Saving Time Correction
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.
- Programmable Forward and Backward Dates
• Dual Alarms with Hardware and Register Indicators
- Hardware Single Event or Pulse Interrupt Mode
• 128 Bytes of User SRAM
