Real-time clocks enhance security, reduce cost

Milpitas, Calif.—Intersil Corp. introduced the ISL12024 and ISL12025 micropower real-time clock/calendar devices, which 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.

The ISL12024/25 continue the trend toward feature integration by combining clock/calendar/alarm functions with 4-Kbits of EEPROM memory and 64 bits of unique ID all in a tiny 8-lead package suitable for both fixed and portable applications. The ISL12025 also includes a CPU supervisor function.

According to Intersil, this level of integration benefits the customer by reducing design cost and footprint and communication with the device is accomplished via the industry-wide I²C interface standard.

“The ISL12024/25 feature an I²C communication link, which provides a reliable communication channel for the unique ID,” said Rouben Gharagozian, marketing director for Intersil's Timing products group, in a statement. “The I²C communication interface is universal and communicates with all devices on the board, saving design time and simplifying the entire system.”

The ISL12024 and ISL12025 are available in 8-lead SOIC and TSSOP packages.

Pricing: The ISL12024 starts at $1.80 each, and the ISL12025 at $1.97 each in 1,000-unit quantities.
