INTERSIL ANNOUNCES THIRD QUARTER EARNINGS

      -     Reports revenue of $113.4 million, exceeding consensus expectations

      -     Grows power management revenue 41.1% from the previous quarter

      -     Achieves adjusted earnings per share (EPS) of $.10, beating
            consensus estimates

IRVINE, Calif. - October 19, 2001 - Intersil Corporation (NASDAQ: ISIL) today
reported financial results for the quarter ended September 28, 2001. Sales were
$113.4 million, a decline of 4.1% compared to the previous quarter but above
previous guidance. Adjusted net income was $11.1 million, or $.10 per diluted
share of common stock, significantly surpassing consensus expectations.
Including amortization and a one-time tax adjustment, the company recorded a net
loss of $3.3 million.

Intersil's gross margins for the third quarter increased to 50.8%, a 50 basis
point gain from the previous quarter, with improvement in both Wireless Access
and Communications Analog. Intersil continues to maintain one of the strongest
balance sheets in the industry, exiting the third quarter with approximately
$624 million in cash and an 8% reduction in inventory during the quarter.

"Intersil's execution was outstanding during the quarter, particularly in our
Communications Analog business where power management revenues grew 41% from the
second quarter," said Intersil President and CEO, Greg Williams. "Our overall
book-to-bill ratio was greater than one, with orders up more than 26% from the
previous quarter. Intersil improved gross margins and operating expenses, which
contributed to growth in our earnings per share. We continue to outperform the
overall semiconductor industry and we enter the fourth quarter optimistic about
our future."

                            RESULTS BY PRODUCT GROUP

WIRELESS ACCESS

Intersil's Wireless Access sales were $29.6 million, a decline of 8.6% from the
second quarter of 2001 due to continued weakness in telecom and fixed wireless
markets. Although sales declined for Wireless Access products during the
quarter, PRISM(R) WLAN product sales were sequentially flat and orders were up
more than 20%, partially due to renewed demand from Intersil's largest
enterprise customer.

"We continue to see strong design activity for our 11 megabit per second (Mbps)
PRISM 2.5 wireless networking solution, which is now built into many notebook
PCs by leading manufacturers including IBM, Hewlett Packard, Panasonic, Compaq
and others," said Williams. "We believe that our strategic alliance for wireless
LAN development with Quanta, the largest notebook manufacturer in Taiwan, is an
important catalyst for embedded wireless technologies in notebooks and
handhelds. We are also encouraged by the rollout of Microsoft(R)'s new
Windows(R) XP operating software, which incorporates 802.11b WLAN drivers as a
standard feature."

"In addition to the notebook design wins, we're excited about innovative new
products that incorporate Intersil's PRISM WLAN chipset, including new wireless
appliances by Panasonic and Sharp," added Williams. "Sharp Corporation, a leader
in LCD TV, has integrated PRISM chipsets into their new AN-SS700 audio/visual
digital transmission system that allows wireless TV reception throughout the
home. We believe these products underscore the widespread adoption of wireless
networking and represent the wide-range of exciting PRISM-based products that
extend beyond traditional PC applications in the home and enterprise."

"Our 11Mbps PRISM product is the most popular wireless LAN radio solution in the
world today," said Williams. "802.11b is the only true global standard and
continues to expand at work, at home and in public places. Wi-Fi (802.11b)
radios now exceed 10 million units worldwide and are helping to create a
significant wireless data infrastructure. We continue to drive new levels of
integration into 802.11 products, making wireless an even more attractive value.
Most notebooks will soon be available with an embedded Intersil WLAN option,
driving even more widespread adoption of Wi-Fi worldwide."

Intersil plans to begin sampling its new PRISM Indigo(TM) 5 GHz wireless LAN
semiconductors during the fourth quarter. The PRISM Indigo solution will support
the United States 802.11a standard and will leverage Intersil's experience in
high volume WLAN applications. The company will continue to work to establish
global, high-data-rate standards. Intersil is also engaged with customers and
Microsoft to develop solutions that are backward compatible with the millions of
802.11b radios already in place.

COMMUNICATIONS ANALOG

Intersil's Communications Analog sales were $45.7 million during the third
quarter, a 14.8% increase from the previous quarter. The Power Management
portion of the analog business showed particular strength, growing 41.1% from
the second quarter, driven by an aggressive production ramp supporting
Intel(R)'s Pentium(R) 4 microprocessor.

The trend toward faster microprocessors that require more power and support from
complex analog power integrated circuits (ICs) continues. Intersil believes that
its Endura(TM) power management solution offers better quality, performance,
ease of use and reliability than its competitors. This enables customers to
transition quickly from concept to production at the lowest overall cost.
Consequently, Intersil is now the world's leading provider of power solutions
for Intel and AMD high-end desktop platforms, and demand for Intersil's Endura
power management products surpassed expectations during the third quarter.
Intersil continues to gain market share in desktop computers and currently
estimates 50% share of the world's power management ICs to support Intel's
Pentium 4.

"We extended our global lead in desktop power management during the third
quarter and continue to see strong design activity for notebook PCs, servers and
broadband gateways," said Williams. "We plan to add to that lead through our
recently announced power management alliance with Primarion. We'll co-develop a
digital control architecture with Primarion to power the next generation of
multi-Gigahertz PCs, servers and notebooks."

"Our alliance with Primarion is one more factor in maintaining Intersil's global
leadership in power management for advanced PC and server customers," said
Williams. "Primarion is a startup company that understands high-performance
power delivery to next generation microprocessors. Primarion was started in 1999
by four former Intel executives and now includes both Intel and Intersil as
significant investors. The combination of Intersil and Primarion's engineering
and technical proficiencies coupled with our global leadership in power
management and channels to market will help accelerate the development of
multi-GHz power management solutions. These digital power solutions will help
complement our rich Endura power management portfolio."

Intersil added several new products to its Endura power management family during
the third quarter including the world's first hot swap IC to support InfiniBand
- a new, gigabit-range communications specification for servers and storage
networks that's backed by an industry association of over 200 members.

OTHER ANALOG

As expected, sales of Intersil's other analog products during the quarter
decreased due to seasonality and continued soft demand. Revenue declined 17.4%
during the third quarter to $38.1 million. The company's fab consolidation and
transition out of automotive products is on track for completion by mid-2002,
which should lead to further improvement in total analog margins.

BUSINESS OUTLOOK

"Based on the strength of our power management and wireless access businesses,
we expect sequential revenue growth of 3-5% in the fourth quarter of 2001," said
Williams. "We anticipate gross margins of 51% and expect an increase in earnings
per share (EPS) to approximately $.11. We believe that Intersil is uniquely
positioned to take advantage of the trend towards faster and more powerful
computing and wireless mobility - providing power and wireless networking
solutions that enable connectivity for people at work, at home and on the go."
