Renesas’ Automotive Gateway Solution for R-Car S4 SoCs

Renesas Electronics has introduced an innovative automotive gateway solution with R-Car S4 system on chips (SoCs) and power management ICs (PMICs) for next-generation vehicle computers, communication gateways, domain servers and application servers.

Renesas Renesas’ new solution meets the automotive industry’s high demands for high performance, high-speed networking, high security and high functional safety levels that are required as E/E architectures evolve into domains and zones.

“As the vehicle architectures evolve, safe connection to cloud services and secure management with in-vehicle control systems are major challenges,” said Takeshi Kataoka, Senior Vice President and General Manager of Automotive Solution Business Unit at Renesas. “As an automotive market leader, we have addressed these challenges with our new R-Car S4 solution, and global OEMs have already begun to design next-generation systems with this solution.”

The solution also dramatically improves development efficiency by enabling software reusability and including the new best-in-class PMICs designed to work seamlessly with the R-Car S4.

The Renesas R-Car S4 is one of the first products in Renesas’ 4th-generation R-Car Family. It includes multiple Arm® Cortex® A55, Cortex R52 and is the first to implement an RH850 MCU for control domain management.

R-Car S4 SoCs offer a huge number of automotive interfaces such as 16x CAN FD, 16x LIN, 8x SENT, 1x FlexRay, 4x PCIe V4.0 and also a high-bandwidth 3 x 2.5Gbit Ethernet Switch to enable rich communication and connectivity options both inside and outside of the vehicle.

The R-Car S4 solution allows designers to re-use up to 88 percent of software code developed for 3rd generation R-Car SoC and RH850 MCU applications.

The new PMICs for R-Car provide advanced power modes that support extremely low power operation. The RAA271041 PMIC accepts the vehicle’s 12V supply and supports wide operation for load dump and cold cranking pulses while providing the first-stage regulation.

Renesas will provide the evaluation boards as a Winning Combination solution featuring the R-Car S4 device, the RAA271041 and RAA271005 PMICs, and a Renesas timing IC (Auto clock RC2121x).

This pre-tested solution will reduce risk in the board design and will further shorten the development cycle.
