    Lattice Semiconductor Reports Second Quarter Financial Results

    HILLSBORO, Ore.--(BUSINESS WIRE)--July 22, 2004--Lattice
Semiconductor Corporation (Nasdaq:LSCC) today announced financial
results for the second quarter ended June 2004.
    Revenue for the second quarter was $60.9 million, an increase of
three percent from last quarter's revenue of $59.1 million and up
eight percent from the $56.6 million reported in the same quarter a
year ago.
    Quarterly revenue from PLD products was $49.8 million, or 82
percent of total revenue, and grew four percent sequentially.
Quarterly revenue from FPGA products was $11.1 million, or 18 percent
of total revenue, and declined two percent sequentially but increased
24 percent on a year over year basis. Quarterly revenue from New
products, now 16 percent of total revenue, grew 28 percent
sequentially and more than doubled on a year over year basis.
    Net loss for the second quarter was $16.0 million ($0.14 per
share). This loss includes a $17.1 million charge for amortization of
intangible assets. Excluding these charges, income for the quarter was
$1.1 million ($0.01 per share). These non-cash amortization charges
have been highlighted as they are not expected to continue at these
levels and are currently expected to be entirely eliminated in 2007.
The Company believes exclusion of these charges more closely
approximates its cash earnings performance. A reconciliation of
non-GAAP income to GAAP loss accompanies the financial tables in this
earnings release.
    "Last quarter we made two significant new product announcements,"
stated Cyrus Y. Tsui, chairman and chief executive officer. "First, we
launched the initial wave of our planned next generation FPGA products
with the introduction of the LatticeEC(TM) and LatticeECP-DSP(TM)
families. The first device of these new FPGA families will be
production released during the current quarter, ahead of schedule.
Both FPGA families were designed from the ground up in order to
optimally balance emerging customer requirements in terms of cost,
architectural features and performance. As the FPGA market is rapidly
transitioning from high-priced, low-volume devices to low-priced,
high-volume devices, we believe the timing of these new FPGA product
families is excellent. Second, we entered the timing IC market with
our revolutionary ispClock(TM) family of in-system programmable clock
management devices. Combining our proprietary programmable mixed
signal technology with high-performance programmable logic, ispClock
devices offer an unprecedented level of performance and flexibility in
support of advanced clock network design. We are pleased with the
customer reception to our recent announcements and expect these new
product families to open new avenues of revenue growth for Lattice
during 2005."

    Business Outlook -- September 2004 Quarter:

    --  Revenue is expected to be flat, plus or minus two percent;

    --  Gross margin percentage is expected to be approximately flat;

    --  Total operating expenses are expected to be approximately
        flat;

    --  Intangible asset amortization is expected to decline by
        $11.1 million to approximately $6 million; and

    --  Other Income is expected to be approximately $3 million.

    On July 23, 2004, Lattice will hold a telephone conference call at
5:30 am (Pacific Time) with financial analysts. Investors may listen
to our conference call live via the web at www.lscc.com. Replays of
the call will also be available at www.lscc.com. On September 9, 2004,
we plan to publish a "Business Update Statement" on our website. Our
financial guidance will be limited to the comments on our public
quarterly earnings call and these public business outlook statements.
Additionally, during the September 2004 quarter, Lattice plans to
participate in an investor conference sponsored by Schwab Soundview
Capital. Specific presentation dates and times are posted on our
website at www.lscc.com.

    The foregoing paragraphs contain forward-looking statements within
the meaning of the federal securities laws including statements about
future quarterly financial results, revenues, customers, product
offerings and the Company's ability to compete. Investors are
cautioned that actual events and results could differ materially from
these statements as a result of a number of factors, including the
possibility that further accounting adjustments may be required and
the effectiveness of changes to the Company's internal controls, as

demand for the Company's new products, the Company's dependencies on
our silicon wafer suppliers, the impact of competitive products and
pricing, technological and product development risks. The Company does
not intend to update or revise any forward looking statements, whether
as a result of events or circumstances after the date hereof or to
reflect the occurrence of unanticipated events.

Notes:

(1) Intangible assets subject to amortization aggregate $51.1 million,
    net, at June 30, 2004 and relate to the acquisition of Cerdelinx
    Technologies, Inc. on August 26, 2002, the acquisition of the FPGA
    business of Agere Systems, Inc. on January 18, 2002 and the
    acquisition of Integrated Intellectual Property Inc. on March 16,
    2001. These intangible assets are amortized to expense generally
    over three to seven years on a straight-line basis. Intangible
    asset amortization will decline to approximately $5.8 million in
    the September 2004 quarter as amortization of intangible assets
    related to the June 1999 Vantis acquisition was completed in the
    June 2004 quarter.

(2) Includes $1.3 million, $0.8 million and $0.8 million of deferred
    stock compensation expense for the quarters ended June 30, 2004,
    March 31, 2004 and June 30, 2003, respectively, attributable to
    Research and Development activities. Includes $2.1 million, and
    $4.1 million of deferred stock compensation expense for the
    six-month periods ended June 30, 2004, and June 30, 2003,
    respectively, attributable to Research and Development activities.

(3) For all periods presented, the computation of diluted net loss per
    share excludes the effect of stock options and our convertible
    notes as they are antidilutive.
