Real-Time Clock/Calendar with Embedded
Unique ID
The ISL12024IRTCZ device is a micro-power real-time clock
with embedded 64-bit unique ID, timing and crystal
compensation, clock/calender, power-fail indicator, two
periodic or polled alarms, intelligent battery backup
switching, and integrated 512x8-bit EEPROM configured in
16 Bytes per page.
The device contains a 64-bit unique ID number for security
and product identification applications. It is housed in a tiny
3mmx3mm TDFN package for small handheld applications.
The clock output defaults to 32.768kHz on initial power-up
for low power microcontroller clocking applications. The low
800nA battery supply current extends backup battery life.

NOTE: These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials, and
100% matte tin plate plus anneal (e3 termination finish, which is RoHS
compliant and compatible 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.
