Overview
Description
Automotive information devices today integrate IT such as cloud computing with smartphones, and functions for safety such as around-view monitoring with onboard camera to offer drivers higher security, safety, and conformity. As integrated dashboard systems improve and become more and complex, auto makers require higher performance, function, and product quality. This results in higher difficulty in hardware/software development, rising development cost, longer development period, and difficulty in maintaining product quality.
Renesas has introduced a new product, the R-Car M2, designed to address growing integrated dashboard and information device market demands, as well as a new low-cost development tool supporting this new product. In addition, the R-Car Consortium is also expanding with many partners around the world, providing you with more choices for supporting product development and making it easier to resolve development issues.
Features
- Three times the CPU performance, six times the graphics performance, and three times the memory bus performance of the previous same-class product, the R-Car M1, and even higher performance characteristics than the existing high-end product, the R-Car H1
- Optimized functions to mid-range automotive information devices to realize software compatibility in the product family
- Offers low-cost software development board to expand development partners
