Auto MCU integrates 2D and 3D graphics for next gen clusters



Spansion has expanded its Traveo range of automotive MCUs with the addition of a device which combines 2D and 3D graphics with a Cortex-R5 core. 
Matthias Bräuer, director of automotive MCU marketing, said: "We are combining a traditional MCU with graphics capability. The device is aimed at hybrid clusters with pointers and a display. It not only supports 2D graphics, but also allows manufacturers to take a step into 3D." 

There will be two variants: the S6J324C series, which enables 2D graphics; and the S6J326C, which supports 2D and 3D graphics. Both series support the Spansion HyperBus interface. Bräuer noted: "Although this device integrates graphics memory on chip, it still needs to access external memory. HyperBus allows data to be transferred at up to 333Mbyte/s." 

In terms of graphics, the S6J32x parts are capable of supporting up to six standard gauges, as well as head up displays. "In some cases," Bräuer continued, "clusters won't have traditional pointers. Instead, there will be virtual instruments and the graphics element can generate fast rotating elements for a natural look." The display controller can handle two outputs as well as accepting a video input. Safety concerns are addressed by displaying safety critical information using a separate graphics layer.
