The TC90175XBG is aimed at the larger, higher resolution driver support information displays that are increasingly used in vehicles for applications other than navigation. Toshiba’s new processor is pin-compatible with the previous TC90195XBG, which supports the composition of two pictures in a single display. The TC90175XBG has a reduced frame memory and targets applications that do not require two-picture composition. This provides designers with the flexibility to choose the most appropriate IC for a given application.
The new processor supports Full HD (1920×1080 resolution) panels, improving on the support for wide VGA (800×480) of the company’s earlier products. Picture separation mode and two independent outputs allow the device to simultaneously output two digital video signals to a Full HD panel and a wide XGA panel at output resolutions including 1920×1080 (LVDS output) and 1366×768 (LVTTL output). A built-in picture improver capability that incorporates a new ‘area adaptive gamma correction circuit improves contrast.
