• Manufacturer Part Number: MB86291A
• Description: Graphics Display Controller
• Manufacturer: Fujitsu Media Devices Limited

The HSYNC and VSYNC signals must be pulled up outside the LSI as they enter the input state upon reset.
Connect the ACOMPR, ACOMPG, and ACOMPB pins to the 0.1 F ceramic capacitor ahead of the analog
Terminate the AOUTR, AOUTG, and AOUTB pins with a resistance of 75 .
Input 1.1 V to the VREF pin. Between this pin and analog ground, insert a bypass capacitor (one with a
superior high-frequency characteristic such as a laminated ceramic capacitor).
power supply.
Connect the VRO pin to the analog ground with a 2.7 k resistor.
For noninterlaced display in external synchronization mode, input "0" to the EO pin, for example, using
a pull-down resistor.
The GV signal serves to switch between graphics and video for chroma keying. The pin outputs a low
level signal to select video.
