Renesas’ fifth-generation R-Car SoC incorporate chiplet technology to create a flexible platform that can be customized to meet various requirements for each use case. The new platform will offer multiple processor sets from entry-level to higher-end models, and can integrate a variety of IP such as AI accelerators and IP by partners and customers into a single package. This will give users the option to customize designs according to their needs.
The R-Car Gen 5 family is built around Arm-based compute engines and includes a portfolio of high-performance 64-bit SoCs, crossover 32-bit MCUs and automotive control 32-bit MCUs that enable improved flexibility, adaptability and higher levels of integration. The new family scales vertically and horizontally across all vehicle models, performance grades and applications and was designed with a heavy focus on software re-use spanning multiple vehicle products and generations.
Through the introduction of the Renesas R-Car Gen 5 portfolio, we are offering customers complete scalability in a family that extends from low-end control MCUs, to moderately complex zonal-domain MCUs and more complex crossover MCUs, to a high-end range of SoC products.

Renesas introduced the RA8T1 microcontroller (MCU) group based on the Arm^® Cortex^®-M85 processor. RA8T1 devices address real-time control of motors, power supplies and other products commonly used in industrial and building automation, as well as smart homes.
The RA8T1 group is the third in Renesas’ RA8 Series, all of which deliver breakthrough performance of 6.39 CoreMark/MHz. All RA8 MCUs take advantage of the high performance of the Arm Cortex-M85 processor and Arm’s Helium™ technology that provides up to a 4X performance boost for digital signal processor (DSP) and machine learning (ML) implementations over the Cortex-M7 core. This added performance in RA8T1 devices can be used for AI functions that can predict maintenance requirements for motors, reducing costly downtime.
All RA8 devices also offer advanced security including Arm TrustZone^® technology, Renesas Security IP (RSIP-E51A), Secure Boot with first stage bootloader in immutable storage, and Pointer Authentication and Branch Target Identification (PACBTI) security extension.
