ISL12025
Real-Time Clock/Calendar with I2C Bus
and EEPROM
The ISL12025 device is a low power real-time clock with
timing and crystal compensation, clock/calender, 64-bit
unique ID, power-fail indicator, two periodic or polled alarms,
intelligent battery backup switching, CPU Supervisor and
integrated 512x8-bit EEPROM, in a 16 Bytes per page
format.
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.
