RTC with
Embedded
Unique ID
ISL12024,
ISL12025
RTC with Factory Programmed 64-bit
Unique ID Enhances Security
The ISL12024, ISL12025 are RTCs with
embedded 64-bit unique ID, 512 x 8-bits
EEPROM, and supervisory functions (ISL12025).
These devices permit data encryption in security
and networking applications and eliminate the
need for an external stand-alone unique ID.
