ISL1221
Real Time Clock/Calendar with Event Detection and Frequency Output
Low Power RTC with Battery Backed
SRAM and Event Detection
The ISL1221 device is a low power real time clock with
Event Detect and Time Stamp function, timing and crystal
compensation, clock/calendar, power fail indicator, periodic
or polled alarm, intelligent battery backup switching with
separate FOUT output and 2 Bytes of battery-backed user
SRAM.
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.
