Renesas Technology±À¥X50´Ú·sªºMCU²£«~(­^¤å¤º®e)

Renesas Technology Corp. has released 50 new products comprising 11 groups as new additions to its R32C/100 Series of MCUs with on-chip flash memory for automotive systems. The MCUs in this series are built around the R32C/100 high-performance 32-bit CPU core, the most advanced available in the M16C Family of complex instruction set computer (CISC) MCUs.



Sample shipments will begin in May 2008 in Japan with the R32C/120 Group and R32C/121 Group, which are suitable for applications such as body control. These will be followed in July 2008 by the R32C/133 Group and R32C/134 Group with on-chip peripheral functions including a communication controller supporting FlexRay, a next-generation automotive communications protocol for next-generation vehicle control applications that is promoted by the FlexRay Consortium. Finally, sample shipments of the R32C/151, R32C/152, R32C/153, R32C/156, R32C/157, R32C/160, and R32C/161 Groups will begin in July 2008 sequentially in Japan.



Recently in the automotive systems field, the number of electronic control units (ECUs) used per vehicle has increased dramatically, and the resulting increase in the volume of data transferred over automotive LANs is striking. In addition, control methods are becoming more complex, which has led to an increase in the size of the software programs used to implement them. As a result, demand is growing for MCUs (the core devices in ECUs) with sophisticated functions and improved performance to execute large programs rapidly.



Renesas Technology has developed and delivered to the market MCU products designed to meet this demand. The R32C/100 Series, part of the M16C Family of CISC MCUs, aims to meet the need for still higher performance with an extensive product lineup offering advanced on-chip peripheral functions. These include communication functions such as multichannel Controller Area Network (CAN) support and a communication controller implementing the FlexRay high-speed communication protocol.



Renesas Technology is currently developing a bus driver with support for FlexRay and plans to eventually offer system solutions including MCU and bus driver components. The company is also an active member of standardization bodies such as the FlexRay Consortium, JasPar, and AUTOSAR. In cooperation with partner tool vendors, Renesas Technology offers software components that comply with standards established by AUTOSAR and JasPar.
