Automotive SoCs for infotainment, cockpit, and digital clusters
Semiconductor manufacturer Renesas Electronics has introduced a new series to its R-Car system-on-chips (SoCs) for entry- to mid-range automotive applications that require high-quality graphics rendering.

The new R-Car Gen3e series of SoCs (R-Car D3e, R-Car E3e, R-Car M3Ne, R-Car M3e, R-Car H3Ne, and R-Car H3e) offers a scalable lineup for entry- to mid-range automotive applications that require high-quality graphics rendering, such as integrated cockpit domain controllers, in-vehicle infotainment (IVI), digital instrument cluster, driver monitoring systems, and LED matrix light. The new devices offer increased CPU performance up to 50k DMIPS and 2-GHz speeds to help carmakers navigate demands for continuous user experience, security, and safety improvements.

“With the growing popularity of applications such as augmented reality navigation and AI-based digital automotive assistants, OEMs and Tier 1s need to balance the skyrocketing demand for larger, higher resolution displays and high-performance chips with rising BOM costs and longer development times,” says Naoki Yoshida, Vice President Automotive Digital Products Marketing at Renesas. “The new R-Car Gen3e devices and reference solutions offer a seamless and cost-effective migration path, providing full compatibility and easy integration with Renesas’ current R-Car Gen3 SoCs to make it quicker and easier for customers to bring their automotive-grade applications to market.”

Key Features of the R-Car Gen3e SoCs:

  • Increased CPU performance – up to 2GHz for the R-Car M3Ne, R-Car M3e, and R-Car H3e devices
  • On-chip real-time Arm Cortex R7 CPU to eliminate the need for an external vehicle controller combined with a Renesas PMIC, reducing overall BOM costs
  • Reduced development times with reference solutions for fast boot, HMI, and functional safety
  • Board support packages updated with the latest versions of the Linux and Android operating systems

R-Car Gen3e Reference Solutions are offered with the following features:

  • Pre-integrated software enables higher application integration, for example for 2D/3D cluster HMI, welcome animation, rear-view camera, and surround view applications
  • VirtIO technology allows developers to easily add the reference solutions to existing applications without changing the existing Linux or Android application
  • Supports ASIL-B system safety requirements for applications such as telltale monitoring and camera freeze detection, as well
