         Lattice Semiconductor Reports Second Quarter Results


    HILLSBORO, Ore.--(BUSINESS WIRE)--July 21, 2003--Lattice
Semiconductor Corporation (NASDAQ:LSCC) today announced financial
results for the second quarter of 2003.
    Revenue for the quarter was $58.2 million, flat with last
quarter's revenue and an increase of three percent from the $56.5
million reported in the same quarter a year ago. Quarterly revenue
from high density CPLD products was $40.3 million, down one percent
from last quarter while quarterly revenue from FPGA products was $9.0
million, an increase of seven percent from last quarter.
    On a GAAP basis, net loss for the quarter was $16.9 million ($0.15
per share). This loss includes an $18.7 million charge for
amortization of intangible assets.
    Non-GAAP income for the quarter was $1.8 million ($0.02 per
share). Non-GAAP earnings exclude non-cash acquisition related
amortization expenses and more closely approximates our cash earnings
performance. A reconciliation of non-GAAP to GAAP earnings accompanies
the financial tables in this earnings release.
    "We remain pleased with the progress of our new product
initiatives," stated Cyrus Y. Tsui, chairman and chief executive
officer. "Since 2002, we have brought to market five major new product
families: our advanced field programmable system chips (FPSC), our
technologically differentiated ispXP(TM) products, our innovative
ispPAC(R) PWR devices, our low power ispMACH(R) 4000Z CPLDs and our
third generation BFW III CPLDs. While the collective revenue of these
new products is still relatively small, it grew very rapidly on a
sequential basis. In addition, these new products accounted for well
over a third of our customer design activity last quarter. We believe
this positive customer reception will drive continued growth for these
products."
    "Last quarter, we introduced our sixth new product family, the
XPIO(TM) 110GXS," continued Tsui. "The XPIO is the industry's lowest
power 10 gigabit per second CMOS transceiver and further solidifies
our leadership position in the SERDES marketplace. We are committed to
embedding this innovative technology into future generations of
advanced FPSC and FPGA products," Tsui concluded.

    Business Outlook - September 2003 Quarter

    --  We believe that, due to seasonality and general industry
        conditions, third quarter revenues will be between $52 million
        and $55 million.

    --  Gross margins are expected to remain at approximately 60% of
        revenue.

    --  Total operating expenses are expected to decrease by
        approximately $1 million to $2 million on a sequential basis.

    --  In conjunction with the previously announced retirement of our
        4 3/4 percent convertible notes, we will incur a one-time
        charge of approximately $5.7 million for the call premium and
        accelerated write-off of remaining unamortized issuance costs
        related to these notes. Total Other Expense, including this
        non-recurring charge, is expected to be approximately $5.6
        million.

    --  Finally, we anticipate reporting a tax credit of $3 million to
        $4 million.

    On July 22, 2003, Lattice will hold a telephone conference call at
5:30 am (Pacific Time) with financial analysts and publish a "Business
Outlook Statement" covering the September 2003 quarter. Investors may
listen to our conference call via the web at www.on24.com. Both the
conference call and our business outlook statement will be available

2003, we plan to publish a "Business Update Statement" on our website
for five calendar days. 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 2003
quarter, Lattice plans to participate in investor conferences
sponsored by Soundview and Bank of America Securities. Specific
presentation dates and times are posted on our website at

the meaning of the Federal Securities laws including statements about
future quarterly financial results, revenues, customers, product
offerings and our 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 overall
semiconductor market conditions, market acceptance and demand for our
new products, risks related to our recent acquisitions and their
integration with Lattice, our dependencies on our silicon wafer
suppliers, the impact of competitive products and pricing,
technological and product development risks.

Notes:
(1) This table reconciles net income (loss) to non-GAAP information,
 which is presented in Appendix 1, on a per-share basis.
(2) Represents write-off of in-process research and development in
 conjunction with the January 18, 2002 acquisition of the FPGA
 business of Agere Systems, Inc.
(3) Tax Shield represents the current period tax deduction available
 from amortizing gross goodwill and other intangible assets
 (approximately $750 million as of December 31, 2002) over 15 years on
 a straight line basis using a 34% tax rate. As of the March 31, 2003
 quarter, we are no longer reporting a Tax Shield.
(4) The effective tax rate is the ratio of income tax expense to
 pretax income. The rate for the six months ended June 30, 2002
 presented in the non-GAAP information presentation is different from
 the rates in the Statement of Operations, due to the difference in
 the proportion of taxable income derived from operations.
