Overview

Description

R-Car S4 enables to launch Car Server/CoGW with 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 R-Car S4 solution allows designers to re-use up to 88 percent of software code developed for 3rd generation R-Car SoCs and RH850 MCU applications. The software package supports the real-time cores with various drivers and basic software such as Linux BSP and hypervisors.

Features

  • 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 45 kDMIPS application performance plus greater than 9 kDMIPS real-time performance
  • Abundant automotive interfaces including 16x CAN FD, 16x LIN, 8x SENT, 1x FlexRay, 2x 2-lane PCIe 4.0 allow a wide range of connectivity inside the vehicle
  • Integrated 3-port 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
  • Incorporated 8MB SRAM to execute code on the RH850 G4MH core with low latency
  • Multiple hardware security modules (HSMs) and firewall IP 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
