Renesas expands R-Car SoC line to boost performance, integration
New R-Car Gen3 SoCs with 2 GHz clock speed maximize scalability and software reuse, and offer stronger application integration as well as increased functional safety for entry to mid-range systems.

Renesas is expanding its range of R-Car SoCs (system-on-chips) for in-vehicle applications with a new series, R-Car Gen3e. With six new members, the new R-Car Gen3e SoC series offers a scalable product line for entry- to mid-range applications that require high-quality graphics rendering. These include integrated cockpit domain controllers, in-vehicle infotainment (IVI), digital instrument clusters, driver monitoring systems and LED matrix lighting.

The devices extend the R-Car Gen3 SoCs with increased CPU performance of up to 50 k DMIPS and a speed of 2 GHz. This enables OEMs and tier ones to meet the ever-increasing demands for user-friendliness and functional safety.

To shorten development time and reduce the BOMs, the manufacturer provides so-called "winning combination solutions" with the R-Car Gen3e SoCs. Customers can combine the R-Car Gen3e SoCs with Renesas' high-precision timing ICs and power management products.

"With growing popularity of applications such as augmented reality navigation and AI-based digital assistants in cars, OEMs and Tier1s must balance the rapidly increasing demand for larger, higher-resolution displays and high-performance chips with rising BOM costs and longer development times," said Naoki Yoshida, vice president automotive digital products marketing at Renesas. "The new R-Car Gen3e SoCs and reference solutions provide a seamless and cost-effective migration path that offers compatibility and easy integration with Renesas' current R-Car Gen3 SoCs. This enables users to bring their automotive applications to market faster and easier."

Key features of the R-Car Gen3e SoCs: R-Car D3e, R-Car E3e, R-Car M3Ne, R-Car M3e, R-Car H3Ne and R-Car H3e include

  • Increased CPU performance - up to 2 GHz for the R-Car M3Ne, R-Car M3e and R-Car H3e devices
  • Arm Cortex R7 on-chip real-time CPU that, when combined with a Renesas PMIC, eliminates the need for an external automotive controller, reducing overall BOM costs
  • Shorter development times with reference solutions for fast start, HMI and functional safety
  • Updated board support packages with the latest versions of Linux and Android operating systems
