San Francisco, Calif., April 23, 2003 — Oki Semiconductor, a leading technology partner for the new era of digital communications and convergence, today announced the fulfillment of its strategy to bring ARM solutions to the broader embedded world, following the launch of a series of Oki advantage microcontrollers™ since the beginning of 2003. Featuring ARM's® industry-leading 32-bit RISC architecture, Oki's advantage microcontroller product families - including the ML674K and ML675K series of microcontrollers, and the ML675200 digital audio controller - will be demonstrated at the Embedded Systems Conference at the Moscone Center in San Francisco in the Oki Semiconductor booth,

Oki began its development and marketing of general-purpose and Application Specific Standard Product (ASSP) microcontrollers that were based on the ARM core architecture in 2001. With the adoption of a new ARM strategy and tag line - "Oki advantage microcontrollers™ bring ARM® to the broader embedded world" - Oki has more clearly outlined its strategic partnership with ARM and the benefits to Oki customers of that alliance. Oki's recent product introductions address the unmet needs of the embedded marketplace by offering affordable, high-performance 32-bit ARM7™-core MCU solutions as an alternative to 16-bit proprietary designs. Each series of new products demonstrates Oki's commitment to offering its customers MCUs with all of the advantages of ARM technology, including industry support, out-of-the-box software applications and a wide selection of system development tools, such as the industry's first low-cost ARM tool suite.

"The unveiling of the Oki advantage microcontroller program for our 10 ARM core-based MCU products exemplifies the tremendous momentum Oki has made over the past year in its strategy to bring ARM solutions to the embedded marketplace," said Ike Saeed, vice president of marketing, Oki Semiconductor. "We've made significant steps in rapidly delivering general-purpose ARM microcontrollers and specialized products to meet the low-cost requirements of a whole new set of embedded system designers."

The Oki/ARM Product Families

Since February 10, 2003, Oki's advantage microcontrollers product announcements have included:

Additionally, Oki has made announcements with its partners, including:

Today at the Embedded Systems Conference, Oki is announcing a series of 20 technical hands-on workshops to be held in conjunction with ARM and Unique Memec, Oki's distributor. The workshops are designed to introduce potential MCU customers to the architecture of Oki's ARM-based microcontrollers, to highlight the advantages of ARM technology, and to walk through a simple training project using the ARM RealView Developer Kit for Oki on an actual hardware target.

The first series of workshops will be held from May through August, 2003, in several cities across North America, including: San Jose, CA, Southern California (Orange County, Los Angeles), Chicago, Boston, Baltimore, Cleveland, Huntsville, AL, Richardson, TX, and Toronto and Montreal, Canada.
