Real-Time Clocks suit low-voltage and portable applications.

Press Release Summary:

With operation from 1.4-3.6 V, Series ISL12057/8/9 is suited for battery-powered portable applications such as remote utility meters, multi-function printers, and digital photo albums. Real-time clock and calendar uses external 32.768 kHz crystal that tracks time by date, year, month, week, and hour, minute, or seconds. Measuring 0.55 mm thick, Models ISL12057 and ISL12058 require 2 x 2 mm board space, while Model ISL12059 comes in industry-standard SOIC package.

World's Smallest, Thinnest Real-Time Clocks

Up to 73% Smaller and 45% Thinner than the Competition, Intersil's New ISL12057/8/9 Simplify Design Of Utility E-Meters, Multifunction Printers, Digital Photo Frames and Many Other Devices

MILPITAS, CA-July 14, 2009 - Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog and mixed-signal semiconductors, today introduced three tiny, razor-thin real-time clock (RTC) products that are ideal for low-voltage and portable applications.

The smallest of these breakthrough products, the ISL12057 and ISL12058, require just 2mm x 2mm, a 73% reduction in board space versus their closest competitors. And at only 0.55mm thick, these new 8-lead devices are 45% percent thinner than similar products on the market. The ISL12057 is available in this 2mm x 2mm 8-lead µTDFN plastic package, which offers enhanced ruggedness and durability in portable applications. For added design versatility, the devices are also available in a 3mm x 3mm 8-lead TDFN, and popular MSOP and SOIC package choices.

In addition, the ISL12058 offers package choices in the 2mm x 2mm µTDFN, 3mm x 3mm TDFN, 8-lead MSOP and 8-lead SOIC options.

The ISL12059 is available in the industry-standard SOIC package.

With operation from 1.4V to 3.6V, these new RTCs are ideally suited for battery-powered, portable applications such as remote utility meters, copy/fax/scanner/printers, digital photo albums and hundreds of other applications.
The real time clock and calendar uses an external 32.768 kHz crystal that tracks time by date, year, months, week, and hour, minute or seconds. Multiple selectable alarms allow a flexibility of alarm choices, with outputs for beepers or lights. The calendar is accurate through 2099, with automatic leap-year correction. The two-wire I2C interface in the ISL12057/8/9 is widely used around the world, which simplifies design-in and enhances ease of manufacturability.

The ISL12057/8/9 family of products is Pb-free (RoHS-compliant), pin, and software-compatible with legacy devices for easy design-in.

Pricing and Availability

Pricing starts at $0.92 each in 1,000-piece quantities in all package types for the IS12057, ISL12058 and ISL12059.
