Overview
Description
The R-Car S4 Starter Kit is a low-cost, readily available development board for building software using the Renesas R-Car S4 system on chip (SoC). The SoC delivers high computing performance and an array of communication features for both cloud communication and safe vehicle control. The new starter kit is a less-expensive and readily-available option compared to the existing R-Car S4 Reference Board, which provides a full-scale development environment including an evaluation board and software. Engineers can take advantage of the new kit to easily start their initial evaluation of car servers, connected gateways, connectivity modules and more, for rapid application development.
Features
- Simplifies the process of establishing open-source automotive Linux environments.
- The R-Car starter kits are designed to simplify the task of setting up automotive Linux environments for engineers who are new to the development of automotive software, and are competitively priced so that each developer can be provided with their own kit.
- 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 27 kDMIPS application performance plus greater than 5.3 kDMIPS real-time performance.
- Ethernet TSN x 2
- CAN FD x2, LIN x 1
- 128GiB UFS
- 64MiB Quad SPI flash memory
Applications
- Gateway and domain control
