The Traveo S6J336xx and S6J337xx micro-controllers are dedicated for instrument applications. The 132-MHz MCUs based on Cortes-R5 cores feature up to 2 MiB of embedded flash memory. The products offer an LCD interface, which can be used for a basic display such as the odometer. The interface also supports Thin-Film-Transistor (TFT) display sizes up to 480 pixels by 240 pixels with a sequencer that simplifies control of the meter display. It can be used to show diagnostics such as tire pressure or that a door is open. 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. The MCUs also support on-chip sound mixing, eliminating the need for an external mixing IC.

The S6J351Cx series is targeted for body electronics applications. It also leverages Cypress' 40-nm flash memory technology and integrates a 132-MHz Cortex-R5 core. All the above-mentioned products are sampled now. Mass production will start in first quarter of 2018. The MCUs are each available in a 144-pin or 176-pin thermally enhanced quad flat package (TEQFP), and additional package options are in development.

"Our newest 40-nm MCUs add to the industry-leading scalability of the Traveo platform for instrument clusters, giving automotive customers options for simple displays in mass-market vehicles up to our MCUs for advanced 3D color graphics in luxury vehicles," said Takeshi Fuse from Cypress. "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."
