Vehicle Computer Generation 4

The VC4 is based on a complete Renesas chipset. The centerpiece is the R-Car S4 with 8x Cortex®A55 cores, 1x Cortex® R52 core 2x RH850 G4MH delivering up to 27K DMIPS application performance and up to 5.3K DMIPS lock step real-time performance. It incorporates an 8MB SRAM to execute code on the RH850 G4MH cores with low latency.  A rich selection of automotive interfaces including a 3-port Ethernet Switch, 16x CAN FD, 8x LIN, 4x SENT, 1x FlexRay, 4x PCIe V4.0 allow a wide range of connectivity inside the vehicle.

Together with the powerful Renesas power management ICs (PMICs) RAA271041 and RAA271005, which provide advanced power control to support extremely low‑power operation for always‑on, cyclic‑run, and suspend‑to‑RAM modes. The RAA271041 device supports the buck stage when the battery voltage drops during cranking transients as low as 2.5V. The RAA271005 has an integrated 12‑bit SAR analog‑to‑digital converter (ADC) that monitors external signals. Finally, the high‑precision timing devices RC21012 and 5P35023 will provide perfect clocking for all devices.

It is the ideal platform to evaluate new E/E Architectures using the R-Car S4 in gateway, car server, or zone control applications.
