HILLSBORO, OR - MAY 7, 2007 -Lattice Semiconductor (NASDAQ: LSCC) today announced the immediate availability of its comprehensive online shopping service, which is accessed at http://www.latticesemi.com/store and powered by its distribution partner, Mouser Electronics.

The online store is particularly helpful for those customers looking for programmable logic devices that are readily available and do not require a minimum order quantity. Customers also can use a credit card, which makes the purchase process both quick and convenient.

The store’s shelves are stocked with Lattice’s broad portfolio of programmable logic devices, including selected 90nm FPGAs, as well as its ispLEVER® software design tool suite, a wide variety of FPGA and CPLD development boards, and download cables. Shipping is available worldwide, frequently on the same day the order is received.

According to Glenn Smith, Mouser President & CEO, the distributor’s business model is a perfect fit for powering Lattice Semiconductor’s Buy Online program. “Mouser‘s expertise lies in rapid new product introduction and quick delivery of small orders.” Smith said. “We serve the design engineer who needs those small quantities of the newest products, shipped the same day so he can get a jump start on his new design project. We deliver a time-to-market advantage to our customers.” Smith added that the distributor’s broad-based product line, outstanding technical support, and streamlined warehouse operations have also contributed to Mouser becoming the design engineer’s one-stop shop for all the board-level components and associated development tools necessary for total project design.

"We are pleased to offer the convenience and efficiency of online shopping to our customers,” said Steve Donovan, Lattice corporate vice president of worldwide sales. "With over 2,500 devices in stock, our online store allows customers to check device pricing and availability 24/7, and there is no minimum order required.
