Microcomputer Business Unit
Sales from the Microcomputer Business Unit comprised approximately 26% of semiconductor sales in the fiscal year ended March 31, 2007. Main businesses include general-purpose microcontrollers and microcontrollers for automotive applications.
In general-purpose microcontrollers, the unit focuses on flash microcontrollers which customers can readily reprogram as needed. Already, these products are found in a wide range of applications, including home electronics, AV equipment, and industrial machinery. The fiscal year under review in particular saw the unit executing development of all new products based on flash microcontrollers for general-purpose microcontroller products, resulting in expansion of the All Flash product lineup. By April 2007, some 300 products had already been released for the unit's broad lineup of 8-bit to 32-bit products.
As for automotive microcontrollers, the unit boasts a high market share of products for body control and car audio applications. Many customers have also given high marks to the unit's microcontrollers for dashboard and safety applications. Furthermore, the unit began mass production and shipments of IMAPCAR, an LSI for onboard image recognition developed in collaboration with NEC Corporation, Toyota Motor Corporation, and Denso Corporation. Utilizing highly advanced parallel processing technology, IMAPCAR allows for real-time image processing, enabling automobile manufacturers and automotive electrical component manufacturers to easily implement safety mechanisms and collision prevention systems.
On the manufacturing front, the unit moved to further enhance supply stability by shifting to a "multi-fab" mass production system, with NEC Electronics America's Roseville fab now joining NEC Kyushu in the production of automotive microcontrollers.
NEC Electronics is also actively pursuing multi-core microcontrollers. These products, featuring both high performance and low power consumption, are expected to become a key technology in years to come. Leveraging a wide product lineup and stable supply, the unit will deliver microcontrollers that support customer competitiveness, while promoting the development of tomorrow's leading products.
