Renesas unveils automotive gateway solution

Renesas has unveiled an 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.

The solution has been designed to increased demand 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. According to Renesas, the solution dramatically improves development efficiency by enabling software reusability and included the new best-in-class PMICs designed to work seamlessly with the R-Car S4.

The 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 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 also 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. T

It 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.

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.
