Intersil Introduces the Industry's Most Accurate Full-Featured Real Time Clocks

New Line Frequency RTCs Will Enhance the Performance of Power Meters, Security Devices and Consumer Appliances

MILPITAS, CA, Feb. 21, 2007 – Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today introduced the world’s first full-featured, AC-driven Real Time Clock (RTC) devices. The new ICs will be designed into a wide range of industrial and consumer products, from power meters and security devices to white goods and other high-end appliances that require precise measurement of time. With integrated functionality such as dual alarms, event detection and a “brownout” alert, the new ISL12030 and ISL12032 have the broadest feature set of any RTCs on the market.

Traditionally, RTCs have used an external crystal for timekeeping, and over long periods of time, some crystal-based solutions can accumulate significant errors. The 50/60 Hz AC power ubiquitous to the U.S. and Europe is a new and even more efficient method of providing RTCs with a clock source. By using the AC power line for timekeeping, designers can build devices that ultimately perform more accurately and reliably over the long term and better withstand extreme temperature changes.

Other features of Intersil’s new AC-driven RTCs include an automatic crystal oscillator backup in case the AC line frequency is lost (ISL12032); an integrated trickle charger that allows a rechargeable energy source such as a super capacitor or rechargeable battery to be used as a backup supply; dual alarms for reporting problems with system performance; a power status “brownout” alarm that allows the system to save vital information to memory before a complete power loss occurs; time stamp, which records the time and date of events including power loss, recovery, and tampering, a feature particularly important in metering devices; and a battery status monitor that provides warning if battery voltage drops below a certain threshold.

Pricing and Availability
The ISL12030 is available now in an 8 Ld SOIC and is priced at $1.82 each 1,000-unit quantities. The ISL12032 is available now in a 14 Ld TSSOP and is priced at $2.06 each in 1,000-unit quantities. More information is available at: http://www.intersil.com/cda/deviceinfo/0,1477,ISL12032,0.html
