Lattice Semiconductor Updates 2Q12 Guidance

HILLSBORO, OR, Jun 14, 2012 --Lattice Semiconductor Corporation (NASDAQ: LSCC) today updated its guidance for the second quarter ending June 30, 2012, as growth in strategic accounts is being offset by continued weakness in the worldwide distribution channel, especially Europe.

• Revenue for the second quarter 2012 is now expected to be approximately flat to down 3% on a sequential basis. This compares to prior guidance provided on April 19, 2012 that revenue was expected to be approximately flat to up 4% on a sequential basis.
• Gross margin percentage is expected to be approximately 51% plus or minus 1%. This compares with prior guidance for gross margin to be to    approximately 55% plus or minus 1%.
• Total operating expenses are expected to be approximately $39.5 million, including approximately $1.0 million in acquisition related    charges (primarily amortization of intangible assets). This is unchanged from prior guidance.

No conference call will be held in conjunction with this guidance update. Additional information will be available when the Company reports its second quarter 2012 results.
