Renesas Electronics Delivers R-Car H3, First SoC from the Third-Generation R-Car Automotive Computing Platform for the Autonomous-Driving Era

The new R-Car H3 maintains a high level of software compatibility with the other SoCs in the R-Car Family already available: the R-Car H2, R-Car M2, and R-Car E2. The R-Car H3 will maintain high level software scalability for the third-generation R-Car Family.

"The R-Car H3 SoC has the all-round sensing, efficiency and safety characteristics that are essential in connected car technologies,” said James McNiven, general manager, CPU group, ARM. “Alongside the inclusion of the high performance ARM® Cortex®-R7 real-time processor, the SoC also capitalizes on the ARM Cortex-A57 and Cortex-A53 cores in an ARM big.LITTLE™ configuration. This has allowed Renesas to deliver advanced vision and detection capabilities while controlling power and achieving the stability that safety-critical electronics demand.”

“Imagination is delighted to see the introduction of the R-Car H3 which includes or our high performance PowerVR GX6650 graphics engine,” said Tony King-Smith, Imagination Technologies EVP marketing. “GX6650 delivers premium graphics performance and features to enable future cockpit experiences, as well as comprehensive GPGPU capabilities.”

“We are pleased to partner with Renesas to provide QNX® software support for the new R-Car H3 SoC,” said John Wall, Senior Vice President and Head of QNX Software Systems, a subsidiary of BlackBerry. “Through this collaboration, we can help accelerate the delivery of next-generation infotainment and ADAS systems that combine the performance of Renesas’ R-Car H3 SoCs with the proven reliability and scalability of QNX OS technology.”

"Next-generation automotive electronics must be designed with security and safety as the top priority,” said Tim Reed, Vice President of Advanced Products, Green Hills Software. “By offering our proven INTEGRITY real-time operating system and Multivisor secure virtualization solutions with the R-Car’s safe and reliable technologies, automotive OEMs and Tier 1’s can be confident in realizing this important design goal.”


Samples of the R-Car H3 are available now. Mass production is scheduled to begin in March 2018 and is expected to reach a volume of 100,000 units per month in March 2019. (Availability is subject to change without notice.)
