Intersil's Real-Time Clocks Enhance Security While Reducing Cost and Footprint

Intersil Corporation, a world leader in the design and manufacture of high-performance analog semiconductors, today introduced the ISL12024 and ISL12025 micropower real-time clock/calendar devices. These devices feature an integrated factory-set 64-bit unique ID that is read-only and tamper-proof for increased security and reduced footprint and BOM cost.

Intersil's ISL12024/25 Feature a Permanent 64-Bit Unique ID Integrated with Standard Clock, Calendar and Alarm Functions in a Tiny Package; ISL12025 Also Adds a CPU Supervisor and Watchdog Timer for Greater BOM Reduction

The ISL12024/ 25 continue the trend toward feature integration by combining clock/calendar/alarm functions with 4Kbits of EEPROM memory and 64 bits of unique ID and the ISL12025 also adds a CPU supervisor function, all in a tiny 8-lead package suitable for both fixed and portable applications. This level of integration benefits the customer by reducing design cost and footprint and communication with the device is accomplished via the industry-wide I² C interface standard.
