ISL12025
FN6371.1
Real-Time Clock/Calendar with 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 512 x 8-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.

with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.

NOTES:
3. RESET Inactive (no reset).
4. VIL = VDD x 0.1, VIH = VDD x 0.9, fSCL = 400kHz.
5. VRESET = 2.63V (VDD must be greater than VRESET), VBAT = 0V.
6. Bit BSW = 0 (Standard Mode), VBAT 1.8V.
7. Specified at +25°C.
8. In order to ensure proper timekeeping, the VDD SR- specification must be followed.
9. Parameter is not 100% tested.
10. tWC is the minimum cycle time to be allowed for any non-volatile Write by the user (it is the time from valid STOP condition at the end of Write
sequence of a serial interface Write operation) to the end of the self-timed internal non-volatile write cycle.
