Automotive MCU range expanded with support for CAN-FD

Cypress has expanded its Traveo automotive MCU family with devices that support the CAN Flexible Data rate (CAN-FD) standard, enabling large amounts of data to be exchanged between CAN nodes within in vehicle networks.

Manufactured on a 40nm process, the new MCUs offer advanced system features, high-quality sound and graphics, and can drive up to six traditional mechanical gauges. Meanwhile, integrated enhanced Secure Hardware Extension (eSHE) support enables the devices to secure data being transmitted, preventing unauthorised connection to ECUs., adding to the scalability of Cypress’ market-leading Traveo family.

Takeshi Fuse, senior vice president of Cypress’ automotive business unit, said: “These new offerings open up cost-effective implementations with high-performance and advanced features to classic instrument cluster applications, including support for CAN FD and eSHE to address industry demand for high-speed in-vehicle networking with advanced security.”

The Traveo S6J336xx and S6J337xx families are based on an ARM Cortex-R5 core running at up to 132MHz. They feature up to 2Mbyte of embedded flash and an LCD interface that supports 4com x 32 segment graphics. The interface also supports TFT displays with up to 480 x 240 pixels. A partial wake-up mode allows the MCUs to operate some functions while the core is in sleep mode and to only wake up if needed.

Meanwhile, the MCUs also support on-chip sound mixing, eliminating the need for an external mixing IC.

Also introduced is the S6J351Cx series, which is targeted at body electronics applications.

The three families are sampling and will be in production in Q1 2018. Packaging options are 144 or 176 pin TEQFPs, but Cypress says additional packages are in development.</span>
