Automotive, ARM-based MCUs take high-end graphics to mid-range cars

March 27, 2015 // By Graham Prophet
Cypress Semiconductor has grown its Traveo microcontroller family with a series that provides automotive manufacturers with a cost-effective platform to deliver 2-D and 3-D graphics and advanced functionality for dashboards, head-up displays and HVAC systems in compact vehicles.

The S6J32BA and S6J32DA series build upon Spansion’s announcement of the Traveo 2-D graphics MCU S6J324C series and the 3-D graphics MCU S6J326C series for midsize cars in October 2014.

The Traveo family delivers state-of-the-art 2-D and 3-D graphics, which have been optimised to bring sophisticated and automotive specific graphics functions into the car without increased power and bill of materials requirements. As the first 3-D-capable ARM Cortex-R5 cluster MCU, Cypress says its graphics engine provides greater memory savings, increased safety features and rich image capabilities, without the need for external video RAM. These, in turn, help manufacturers take advantage of lower overall system costs.

The Cypress Traveo S6J32BA and S6J32DA product family includes the ARM Cortex-R5 processor, 1 MB of internal flash, 1 MB of internal video RAM, enhanced secure hardware extension (eSHE) and the HyperBus interface that enables seamless connections with HyperBus memories such as HyperFlash memory and HyperRAM memory. The S6J32BA and S6J32DA series are pin compatible with their predecessors S6J324C and S6J326C, providing customers the flexibility and ease to upgrade without requiring changes to the board layout. The graphics functionality is complemented by an advanced sound system with a 16-bit audio-DAC and a multi-channel mixer.

“This new series of the Traveo family is the first automotive product launched as part of Cypress and is another step forward in bringing the luxury car experience to the mass market. By offering a cost-effective yet high-performance and scalable platform, our customers can affordably deliver 2-D and 3-D graphics and other advanced functionality in compact vehicles,” said Takeshi Fuse, senior vice president of the Automotive Business Unit at Cypress. The Traveo S6J32DA series is sampling now, and the S6J32BA will be sampling in April 2015.
