Description
The R-Car E3e is an upscale to the R-Car D3e SoC for 3D graphics clusters, that brings enhanced 3D graphics rendering performance. As part of the Renesas R-Car family, this SoC also offers the functional safety and security functions that are essential for connected cars as the role of the human-machine interface (HMI) becomes more important. With these features, the R-Car E3e simplifies the task of developing robust systems capable of dealing safely with both malfunctions and cyberattacks
The single-chip design enables the integration of a variety of systems, significantly reducing overall system development costs and achieving substantial space savings. The R-Car E3e shares the scalability of the R-Car H3e and R-Car M3e for integrated cockpits as well as the R-Car D3e for instrument clusters, establishing the highest level of software reuse. Renesas partner companies with extensive experience in the instrument cluster field are ready to provide operating systems (OS) and HMI tools in addition to system integration support. This greatly reduces the development burden, extending software support to a wide range of vehicles.
