NEXFLASH, LATTICE ANNOUNCE SPIFLASH MEMORY SUPPORT FOR LATTICE FPGA DEVICES

• spiFlash Serial Flash Memories Provide Efficient Configuration Solution for LatticeECP, LatticeEC FPGA Designs

SAN JOSE, Calif., USA - May 16, 2005
NexFlash Technologies, Inc., a pioneer in Serial Flash technology, and Lattice Semiconductor Corp. (NASDAQ: LSCC), a provider of the industry's broadest range of field programmable gate arrays (FPGAs) and programmable logic devices (PLDs), today announced the qualification of NexFlash® spiFlash® Serial Flash memories for use with the LatticeECP™ and LatticeEC™ field-programmable gate array (FPGA) family. Featuring the popular Serial Peripheral Interface (SPI), the spiFlash family offers Lattice FPGA users a pin-, space- and cost-efficient alternative to ordinary FPGA configuration solutions.

Prior to the introduction of the LatticeECP and LatticeEC families, FPGA configuration at power-up was typically handled by dedicated boot PROMs, which could account for more than one-third of the total FPGA solution cost. To address this issue, Lattice introduced the LatticeECP and LatticeEC FPGAs with support for industry-standard Serial Flash, such as the NexFlash spiFlash family. Using spiFlash memories for FPGA configuration helps further reduce costs to effectively compete in price-sensitive volume FPGA applications.

"As the low-cost and high-performance benefits of the LatticeECP and LatticeEC FPGAs continue to create excitement among our customers, we remain focused on helping customers realize the most-efficient 'total FPGA' solution," said Stan Kopec, Lattice vice president of corporate marketing. "The NexFlash spiFlash family, with its industry-compatible interface, broad density range, and low-cost SOIC packaging, is a good match for our FPGAs."

"Our spiFlash family is a perfect complement to LatticeECP and LatticeEC FPGAs," said Robin Jigour, vice president of marketing at NexFlash. "With the spiFlash family fully qualified, we look forward to supporting Lattice customers with their Serial Flash memory needs."

Range of Densities, Space Saving Packages
SpiFlash memories interface with the LatticeECP and LatticeEC FPGAs through the four-pin SPI interface, which can be clocked at frequencies up to 50MHz. The spiFlash family offers a broad range of densities, from one to 32 megabits (M-bits), exceeding the configuration requirements of the FPGAs. Additional memory can be used for cascading multiple FPGAs or storing user data, such as look-up tables, parameters, text, waveforms, and voice prompts, through the SPI interface.

NexFlash offers densities up to 16M-bits in space-saving eight-pin SOIC packages, allowing an easy migration path across densities and using less than 25 percent of the space required for Parallel Flash. All spiFlash products meet industrial-temperature operation, are available in Green "RoHS"-compliant packages and are supported by popular third-party PROM programmers.

Expanding Market for Serial Flash
The Serial Flash memory market is experiencing dramatic growth, with a wide range of applications quickly converting from Parallel to the more pin- and space-efficient Serial Flash technology. Densities in Serial Flash memories, such as members of the NexFlash spiFlash line, have climbed from one M-bit up to 32M-bit. At the same time, the market for such memories is rapidly expanding. According to leading industry analyst Web-Feet, revenues for Serial Flash memories will grow from $275 million in 2004 to $480 million this year, then exceed $1 billion in 2007.
