  Lattice Semiconductor Reports Fourth Quarter and Year End Financial Results

     HILLSBORO, Ore.--(BUSINESS WIRE)--Jan. 24, 2005--Lattice Semiconductor
Corporation (Nasdaq:LSCC) today announced financial results for the fourth
quarter and year ending December 2004.
     For the year 2004, revenue was $225.8 million, an increase of eight percent
from the $209.7 million reported in 2003. During 2004, PLD revenue grew six
percent to $183.1 million and accounted for 81 percent of total revenue while
FPGA revenue increased 15 percent to $42.7 million and accounted for 19 percent
of total revenue.
     Net loss for 2004 was $52.0 million ($0.46 per share), an improvement from
the net loss of $91.8 million ($0.82 per share) reported in 2003. These losses
include charges of $47.3 million and $77.1 million, respectively, for the
amortization of intangible assets. Excluding these charges, the loss for 2004
was $4.7 million ($0.04 per share) as compared to a loss of $14.7 million ($0.13
per share) for 2003. These non-cash amortization charges have been highlighted
as they are currently expected to be substantially eliminated in 2008. The
Company believes exclusion of these charges more closely approximate its cash
earnings performance. A reconciliation of non-GAAP loss to GAAP net loss
accompanies the financial tables in this earnings release.
     For the fourth quarter of 2004, revenue was $48.5 million, a decrease of
eight percent from the $52.8 million reported in the same quarter a year ago and
a decrease of 15 percent from the $57.3 million reported last quarter. Quarterly
revenue from PLD products was $39.6 million, or 82 percent of total revenue, and
declined 14 percent sequentially. Quarterly revenue from FPGA products was $8.9
million, or 18 percent of total revenue, and declined 21 percent sequentially.
Quarterly revenue from New products, now 26 percent of total revenue, grew 5
percent sequentially and 72 percent on a year over year basis.
     Net loss for the fourth quarter was $13.1 million ($0.12 per share). This
loss includes a $5.8 million charge for amortization of intangible assets.
Excluding this charge, loss for the quarter was $7.4 million ($0.07 per share).
This non-cash amortization charge has been highlighted as these charges are
currently expected to be substantially eliminated in 2008. The Company believes
exclusion of these charges more closely approximate its cash earnings
performance. A reconciliation of non-GAAP loss to GAAP net loss accompanies the
financial tables in this earnings release.
     "Last quarter was a difficult one for the PLD industry and our results
reflect these unfavorable market conditions," stated Cyrus Y. Tsui, chairman and
chief executive officer. "On a positive note, we posted sequential revenue
growth from our New products, reduced our inventory balance and continued to
generate positive cash flow from operations before the payment of a $25 million
advance to our foundry partner Fujitsu."
     "The year 2004 has been a period of transition for Lattice," continued
Tsui. "We sustained a large R&D investment in order to support the development
of a full portfolio of next generation FPGA product families. We believe these
new products will be critical to our long-term success and ability to grow our
revenue and market share in this attractive segment. During the third quarter,
we initiated the market roll-out of the first of these new families, the
LatticeEC(TM) and LatticeEC-DSP(TM), and are now moving quickly towards volume
production availability of all 12 devices in these families. At this early
stage, we remain pleased with the initial customer reception and are optimistic
about the market potential for these new FPGA families. Looking forward, we
expect this new product momentum to continue throughout 2005 as we continue our
roll-out of additional families of differentiated products targeted at the FPGA
market."

     Business Outlook - March 2005 Quarter:

     --   Quarterly revenue is expected to be $46 million to $49 million;

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

     --   Total operating expenses are expected to increase by $1 million to $2
          million;

     --   Intangible asset amortization is expected to be approximately $4.4
          million; and

     --   Other Income is expected to be approximately $1 million.

     On January 25, 2005, Lattice will hold a telephone conference call at 5:30

Notes:

(1)  This table presents operating information which is consistent
 with the information reported by Thompson Financial, Reuters and
 Zacks for Lattice Semiconductor Corporation.  A reconciliation to
 GAAP on a per share basis is attached as Appendix 2.
(2)  For all periods presented, the computation of diluted Non-GAAP
 loss excludes the effect of stock options and our convertible notes
 as they are antidilutive.
