Overview
The Spider serves as a dedicated R‑Car S4 reference platform for assessing R‑Car S4–based systems and supporting the development of operating systems, device drivers, and applications. It offers a complete development environment with hardware and software for automotive gateway applications to support the new E/E architecture.
Features
- Reduces the board size and BOM costs through MCU core integration into R-Car system-on-chip (SoC), and uses a single board to control both MCU domain and application SoC domain, which was previously required separately.
- The development board consists of a CPU board with core SoC, power management IC (PMIC) and memory, and an interface board, enabling support for a variety of networks.
- Supports 16 channels of CAN FD (can be used as 16 channels of LIN and 8 channels of SENT by multi-function), 2 channels of FlexRay, 2 channels of PCIe v4.0 x2 lanes, and 3 channels of 5G-USXGMII for Ethernet.
- The core system is realized by installing the R-Car S4, LPDDR4x-3200 memory, and HyperFlash™ memory on the CPU board, which contributes to shortening the time-to-market by simplifying the design.
- 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.
