      Intersil Corporation Announces First Quarter 2003 Financial Results

    --Achieves $164.4 million in revenue and grows orders sequentially in all
                                 Product Groups
                        --Meets revenue and EPS guidance
         --Generates more than $34 million in cash flow from operations


MILPITAS, CA, April 23, 2003 - Intersil Corporation (NASDAQ: ISIL), a world
leader in the design and manufacture of high performance analog and wireless
networking solutions, today reported financial results for the first quarter
ended April 4, 2003. On a generally accepted accounting principles (GAAP) basis,
net revenue was $164.4 million, an increase of 23% from the first quarter of
2002. GAAP net income for the first quarter of 2003 was $13.7 million or $0.10
per diluted share. This compares to net income of $13.8 million or $0.13 per
diluted share for the same period a year ago.

Intersil believes that adjusted revenue and earnings information is a more
accurate representation of its quarterly operating performance and has therefore
chosen to provide this information to investors for a more consistent basis of
comparison. Intersil also uses this adjusted information internally to evaluate
and manage the company's operations.

Revenue from ongoing operations, including Elantec(R) for all periods and
excluding Automotive, was $162.2 million, an increase of 10% over the prior year
and a decrease of 1% from the fourth quarter of 2002. Excluding amortization of
intangibles and other one-time items, adjusted net income for the first quarter
was $18.3 million or $0.13 per diluted share of common stock. This compares to
adjusted net income of $17.8 million or $0.13 per diluted share for the first
quarter of 2002.

"Our Power Management and Elantec Product Groups both achieved impressive
sequential growth in the first quarter, and we're pleased with Intersil's total
performance during what is historically a seasonally weak quarter for the
industry," said Rich Beyer, Intersil's president and CEO. "Our Wireless
Networking Product Group and total analog business each grew on an annual basis.
Our orders position improved substantially with strong sequential orders growth
in each of our Product Groups."

"Intersil improved gross margins 30 basis points to 53.0% this quarter and our
analog gross margins reached an all-time high," added Beyer. "The company
generated more than $34 million in cash flow from operations and exited the
quarter with a very strong cash and liquid investments position of over $633
million."

Results by Product Group

Revenue for Intersil's Power Management products reached a record $54.3 million
during the first quarter, an increase of 3% from the prior quarter and 26% from
the first quarter of 2002. Intersil's continued expansion from desktop power
management into notebook, portable and peripheral applications helped the
company grow its revenue during a historically soft seasonal quarter. Intersil's
Endura(TM) power management products for notebooks, graphics cards and DDR
memory all experienced significant growth during the first quarter. Intersil
received more orders for notebook products in the first quarter than it had for
all of 2002. Strong design win momentum for Intersil's graphics card and DDR
memory solutions helped the company's market share to grow to more than 50% of
next-generation products. This should help drive continued revenue growth for
Intersil's Power Management Product Group during all of 2003 and beyond.

Elantec product sales also increased during the quarter, growing 6% sequentially
and 7% over the first quarter of the prior year to $27.2 million. Revenue growth
for the Elantec Product Group was driven by demand for its laser diode drivers
(LDD) for new DVD recorders, as Intersil continues to benefit from increasing PC
attach rates for DVD recordable drives. The company also experienced increasing
demand for its DSL products and announced during the quarter that it has now
shipped more than 30 million DSL ports since introducing the world's first DSL
line driver in 1995.

Intersil's Standard Analog revenue decreased 1% both sequentially and from the
same quarter of 2002 to $29.8 million. Based upon recent improvement in customer
ordering patterns, there now appears to be some strengthening in the standard
analog demand environment. As a result, Intersil expects a return to sequential
revenue growth in Standard Analog in the second quarter. Intersil continues to
add to its standard analog portfolio with high-precision, low power,
space-saving products such as analog switches for Voice over Broadband and
RS-232/485 interface. The company's focus on portable markets within standard
analog has helped establish Intersil as the number one supplier of analog
multiplexers and number three supplier of analog switches.

As expected, the company reported Automotive product sales of $2.2 million
during the first quarter as Intersil completed its exit of the automotive
business in order to focus on higher growth and more profitable markets.

Intersil's Wireless Networking sales decreased 9% from the previous quarter but
grew 4% year over year to $51.0 million. The sequential decline was primarily
due to seasonal softness within the WLAN market as well as ASP declines in 11
Megabit per second (Mbps) 802.11b. As expected, the market began to shift to
higher data rate 54 Mbps products during the quarter. Lead customers including
D-Link, NETGEAR, SMC, corega and USI have already begun ramping new products
based on Intersil's higher data rate PRISM(R) WLAN solutions, and approximately
20% of the first quarter wireless networking revenue came from these new
products. Intersil also began shipping its new dual band 802.11a, b and g WLAN
solution, PRISM Duette(TM), during the first quarter. Continued strong orders
demand for these new solutions should result in a resumption of wireless
networking growth in the second quarter.

Business Outlook

Looking ahead to the second quarter, Beyer said, "Given the increasing strength
in orders in Q1 and our new product launches, we expect to resume sequential
revenue growth in the second quarter. We expect revenue to grow 5 to 7% in the
second quarter to between $172 and $176 million, with all of our product groups
contributing to our growth. We expect earnings to grow faster than revenues, due
to continued improvement in gross margins and continued leveraging of our
operating expenses. We anticipate adjusted earnings per share to increase to
$0.15-$0.16 in the second quarter."
