MB86291A Description
The MB86291A is an evolved version of the Fujitsu MB86290A graphics controller designed for use in a car navigation system or amusement equipment. The MB86291A is a graphics display controller with a geometry processor, digital video capture facility, and on-chip SDRAM. Embedding SDRAM implements data transfer at a higher bandwidth, resulting in faster drawing.
