Secure high-speed networking for automotive body electronics

Cypress Semiconductor have announced new devices in its single-power-supply Traveo automotive MCU family. They provides secure, high-speed networking for body electronics applications. The new S6J342xxx series supports the controller area network flexible data-rate standard for high-speed, in-vehicle networking, enabling large amounts of data to be exchanged between each CAN node. The MCUs address the critical need to secure data on in-vehicle networks with enhanced secure hardware extension support, preventing unauthorised connections to electronic control units (ECUs). The new Traveo series continues the company’s expansion of its broad automotive portfolio that includes MCUs, wireless radios, memories, capacitive-touch solutions and PMICs. The series leverage their 40nm eCT Flash technology for higher performance and reliability. The series delivers rich features and more cost-efficient implementations for body control modules, HVAC systems, collision warning systems, gateways and lighting applications. The MCUs are based on an ARM Cortex-R5 core with robust, 132MHz performance and feature up to 1MB of high-density embedded flash for application storage. A unique partial wake-up mode allows the MCUs to minimise average power consumption. Cypress offers a broad range of variations in the series that enables OEM customers to easily develop derivative solutions. “Cars are becoming more connected both externally and internally, and for in-vehicle networking, our automotive customers are looking for faster performance with robust security to prevent ECUs from being hacked,” said Takeshi Fuse, senior vice president of the Automotive Business Unit at Cypress. “Our new 40nm Traveo MCUs with CAN FD and eSHE support are optimised to enable secure, high-speed, in-vehicle networking to a wide range of body electronics applications. The devices add to the scalability of our Traveo platform, and to Cypress’s unique ability to serve as a one-stop resource for our customers to develop cost-effective system solutions with advanced functionality.”
