Real Time Clock/Calendar with EEPROM
The ISL12029 device is a low power real time clock with
clock/calender, power-fail indicator, clock output and crystal
compensation, two periodic or polled alarms (open drain
output), intelligent battery backup switching, CPU
Supervisor, integrated 512 x 8 bit EEPROM configured in 16
byte per page.
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.
