The MB86293 graphics display controller features a 166MHz geometry processor and a 133MHz rendering engine that enables the device to have an embedded rendering capability of 1 gigapixels per second.

The controller performs rendering, shadowing, and framing of aerial, 2D, and 3D maps in car navigation systems.

A member of the MB86290 series of graphics controllers, the MB86293 is equipped with rendering functions to display smooth lines and polygons of any shape, and sophisticated three-dimensional graphics-management functions that can display high-resolution images, correct distortions for renderings in three-dimensional space, and remove hidden screens.

Two-dimensional capabilities consist of point, line, triangle, polygon, BLT, and pattern rendering.

Three-dimensional capabilities include point, line, triangle, and hidden-screen removal using the Z buffer method, which writes the details of each pixel's depth in the Z buffer memory, then compares the depth information against the Z buffer when completing the polygon draw.

The controller also has special effects capabilities including anti-aliasing, bold and broken line management, alpha-blending, gouraud-shading, texture mapping, perspective collect, and tiling.

The MB86293 provides a maximum display resolution of 1024x768 with an 8-bit-per pixel color palette display, 16-bit per pixel RGB display, and the use of true colors every 5-bits. It also supports the use of two 64x64 pixel hardware cursors.

The controller, which also integrates an external clock operating at 14.32MHz, can be connected to the company's FCRAM or SDRAM devices. Manufactures using the a 0.185m process, the 256-pin plastic HQFP device operates from a 1.8V source and has 3.3V-tolerant I/Os.

The MB86293 is priced at about $48.10, excluding tax.
