Fujitsu Microelectronics America Inc. (FMA) extended its portfolio of graphics display controllers (GDCs) for automotive applications. The new MB86276 is a streamlined version of the MB86296, a three-dimensional (3D) graphics display controller.

The new two-dimensional (2D) GDC MB86276 is designed for the mid-range navigation and entertainment market that is emerging in North America. This device includes many of the features offered in the MB86296, including dual display support, video capture, multiple alpha-blending options, and a 16-bit Z buffer that enables low-level 3D operations.

The MB86276 2D GDC incorporates the display controller, rendering engine and video-input unit developed originally for the MB96296 3D version, along with built-in alpha-blending, anti-aliasing and chroma-keying capabilities, and an up/down video scalar. An optimized central processor allows more direct CPU connections, so the new 2D GDC can be linked to a wide range of processors and controllers from various manufacturers, said FMA.

The MB86276's internal and memory frequency is 133MHz, and the base clock for display operates at 400.9MHz. Display resolutions range from 320 x 240 to 1,280 x 768. Six layers of overlay windows, all of which have a color depth of 8-, 16- or 24bits/pixel, can be used simultaneously, and can be changed in size, position and priority. The maximum logical layer size is 4,096 x 4,096 pixels. Specific layers can be blended easily using the alpha map, which can be freely assigned to any of the six layers and which allows the assignment of 8 bits per pixel.

Internal and external DMA is supported, along with an external 32bit SDRAM interface for up to 64MB of graphics memory. An I2C interface also is included, as are GPIO inputs and outputs.

The MB86276 provides all of the 2D capabilities of the MB96296, including texture mapping, alpha blending, Gouraud shading, flat shading and dual-display output. Using the dual-display mode, explained the company, the GDC can individually drive two connected displays with identical resolution.

The MB86276 is manufactured using Fujitsu's 0.18?m CMOS technology and is housed in 256-pin BGA packages. This device is available for volume orders, with prices starting at $12 each in 100,000-piece quantities.
