CAN FD MCU for bodycontrol in cars

Cypress sampling its new single-power-supply Traveo automotive microcontroller (MCU) family made using 40nm embedded charge-trap (eCT) Flash technology. The new S6J342xxx series provides secure high-speed networking for body electronics applications in automotives. The new S6J342xxx series supports the Controller Area Network Flexible Data-rate (CAN FD) standard for high-speed, in-vehicle networking. CAN FD allows 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 (eSHE) support. It prevents unauthorized connections to electronic control units (ECUs). Cypress suggests this Traveo S6J342xxx series for applications such as body control modules, heating ventilation and air conditioning (HVAC) systems, collision warning systems, gateways and lighting where higher performance, reliability and cost efficiency are the requirements. The Microcontrollers are powered by ARM Cortex R5 core processor operating at 132-MHz with memory up to 1MB of high-density embedded flash for application storage. The low power saving mode achieved through a unique partial wake-up mode. Takeshi Fuse, senior vice president of the Automotive Business Unit at Cypress says, “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”. “Our new 40nm Traveo MCUs with CAN FD and eSHE support are optimized 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”. The Traveo S6J342xxx series is sampling and will be in production in early 2017. The MCUs are available in a 100-pin thermally developed quad flat package (TEQFP), 120-pin TEQFP, 144-pin TEQFP and 176-pin TEQFP. The other variant comes in a 100-pin low profile quad flat package (LQFP), 120-pin LQFP and 144-pin LQFP.
