Highly Integrated R-Car S4 Accelerate Centralization with High Performance, Networking, Security and Safety Features

TOKYO--(BUSINESS WIRE)--#PMIC--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, today unveiled 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' 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. 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.

�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 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 software package supports R-Car S4 application development including the real-time cores with various drivers and basic software such as Linux BSP and hypervisors. In addition, a virtual platform (VPF) is available from a partner company, enabling early software development and evaluation to reduce design time and cost.

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. The RAA271005 is a Safe 11-channel PMIC that takes the RAA271041�s output and steps it down further to the various supply voltages needed by R-Car S4 and its peripherals such as LPDDR4x memory. The RAA271041 and RAA271005 PMICs provide a complete power solution from vehicle battery down to system voltage.

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 (Autoclock RC2121x). This pre-tested solution will reduce risk in the board design and will further shorten the development cycle.

Key Features of the R-Car S4 SoCs

• Eight 1.2 GHz Cortex A55 cores, one 1.0 GHz Cortex� R52 dual core (lock-step) and two 400 MHz RH850 G4MH dual cores (lock-step) deliver up to 27 KDMIPS application performance plus greater than 5.3 K DMIPS real-time performance
• Abundant automotive interfaces including 16x CAN FD, 16x LIN, 8x SENT, 1x FlexRay, and 4x PCIe V4.0 allow a wide range of connectivity inside the vehicle
• Integrated Ethernet TSN switch offers bandwidth of 3 x 2.5 Gbps to deliver fast and low-latency communication in the vehicle backbone and to the outside world. This switch is fully validated by Spirent�s TSN conformance test solutions running on their Automotive C1 test system.
• Incorporated 8MB SRAM to execute code on the RH850 G4MH core with low latency
• Multiple hardware security modules (HSMs) provide enhanced security protection against cyber attacks
• R-Car S4 is compliant to ISO-26262 and supports functional safety according to ASIL B and ASIL D
• 23mm square (R-Car S4) and 19mm square (R-Car S4N) FCBGA packages

Key Features of the PMICs for R-Car

• Programmability enables easy adaption to support R-Car S4 and future R-Car SOCs
• RAA271041 and RAA271005 provide advanced power control to support extremely low power operation for always-on, DeepSTOP, cyclic-run, and suspend-to-ram modes.
• RAA271041 is a pre-regulator that offers two 42V synchronous controllers, one buck and one boost. The device�s boost stage supports the buck stage when the battery voltage drops during cranking transients as low as 2.5V.
• RAA271041 and RAA271005 were developed per ISO-26262 and are capable of supporting system safety requirements up to ASIL D.
• Integrated 12-bit SAR ADC monitors external signals and eliminates an external ADC
• Dynamic Voltage Frequency Scaling changes output voltage to save power
• Optional spread-spectrum clocking mitigates EMI
• Built-in support for R-Car S4 activation streamlines SoC self-test procedures
