Renesas provides Vehicle Computer 4 which is an ideal platform for the development of applications such as gateways, car servers and zone control to realize the next generation of E/E architecture.

The R-Car S4 is an advanced system-on-chip (SoC) with embedded MCU cores capable of ultra-low power operation. Combine with PMICs (RAA271041 + RAA271005) developed for R-Car Gen4 to enable optimal power control and functional safety support.

System Benefits​:

  • Supports vehicle-mounted testing with a robust metal box, vehicle connectors and components for automotive temperature (-40 °C to 85 °C).
  • Supports the newest automotive network technologies (TSN Ethernet Switch, 10BASE-T1S, 1000BASE-RH, 2.5GBASE-T1, etc.) plus legacy networks (CAN, LIN, FlexRay, SENT, etc.) Also, supports analog input, wake-up and real-time clock to increase development usability.
  • Sufficient computing power (up to 27k DMIPS application performance plus greater than 5.3k DMIPS real-time performance) to host the evolving amount of user applications.
  • Allows designers to re-use up to 80 percent of software code developed for three generations of R-Car SoCs and RH850 MCU applications.
  • The combination of pre-regulators and PMICs developed for R-Car S4 can provide various supply voltages to meet functional safety requirements up to ASIL D in accordance with ISO 26262.
