6. 6 © 2010 Renesas Electronics America Inc. All rights reserved. Notes continued from previous page (continued from notes section of previous page) Renesas knows that to best facilitate the further growth and success of ubiquitous computing, we cannot offer just one CPU core or a single family of microcomputers. Thus, taking advantage of the broad span of leading technologies we have built up, we have decided to concentrate our future R&D efforts on five major CPU cores capable of excelling at major elements of the huge task. Each is optimized for addressing the requirements of diverse sets of key applications. With that business plan in mind, allow me to explain the relative positioning of these five architectures within our strong portfolio of MCUs and MPUs. An important design trend in recent years has seen system engineers taking full advantage of all the computing power that IC makers have made available — often right up to the limits of project constraints. As a result, there have been more and more design-ins of chips with 32-bit architectures. Renesas now has three complementary 32-bit microcontroller and microprocessor families aiding that trend. At the top end of the features-and-capability spectrum we offer the devices in the SuperH family, a superscalar RISC architecture that executes two instructions per clock cycle. Devices in the SuperH family deliver up to 1200 DMIPS performance, so they’re ideal for and popular in multimedia, Real-time industrial-control, server, and automotive engine- control applications. We also recommend them for performing video and audio processing on Linux-based systems Our second series of 32-bit system design solutions is the V850 family, which today is the top-selling line of 32-bit microcontrollers, worldwide. The V850 architecture provides high performance (up to 500 DMIPS), yet consumes low power while doing so. System designers have found these devices to be particularly well suited for automotive applications. The lower- frequency V850 chips are optimized for low power. Thus, they are excellent choices for portable medical equipment, for example.
