ML87V3104
LCD Display Controller with Embedded Display Memory
FEDL87V3104-03
Issue Date: Nov. 28, 2003
GENERAL DESCRIPTION
The ML87V3104 is an LCD graphic display controller intended for use in medium to small-sized equipment
having such as QVGA grade medium-sized LCD panels, such as PDA or portable information terminals.
Since this LSI device has an internal display memory, use of this device reduces the component count. It is
possible to set an easy to use configuration of the display memory size, such as 1024

1024 dots
×
4 bits or 2048
×
256 dots
×
8 bits, depending on the application at hand, and it is possible to access the image data without having
to be concerned about address conversion.
The area specified in the display memory can be output on the display.
The display data and the control information can be set by the host CPU.
