LATTICE SEMICONDUCTOR UPDATES

GUIDANCE FOR FIRST QUARTER

HILLSBORO, OR – March 11, 2009 - Lattice Semiconductor (NASDAQ: LSCC) today announced its business update for the first quarter of 2009.

• First quarter revenue is now expected to be down approximately 10% to 15% sequentially which is a revision from previous guidance of down 10% to 20% sequentially.

Bruno Guilmart, Lattice President and Chief Executive Officer commented, “Except for the wireless communications market in Asia which is showing a better than expected revenue trend, we continue to have limited visibility with regards to our broader business base.”

No conference call will be held in conjunction with this guidance update. Additional information related to the first quarter will be available when the Company reports its first quarter 2009 results.

Forward-Looking Statements

The foregoing business update contains forward-looking statements. Lattice believes the factors identified below in connection with each such statement could cause actual results to differ materially from the forward-looking statements.

Estimates of future revenue are inherently uncertain due to the high percentage of quarterly “turns” business, as well as such factors as the demand for our products, and our ability to supply products to customers in a timely manner.

In addition to the foregoing, other factors that may cause actual results to differ materially from the forward-looking statements herein include global economic uncertainty, overall

1

semiconductor market conditions, market acceptance and demand for our new products, our having clearly focused our business on identifying and pursuing programmable logic opportunities where we have sustainable and differentiated market positions, our dependencies on our silicon wafer suppliers, the impact of competitive products and pricing, technological and product development risks, the compromised liquidity of our auction rate securities, the transition to a new executive management team, and the other risks that are described herein and that are otherwise described from time to time in our filings with the Securities and Exchange Commission. 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.
