LCD CONTROLLER
■
GENERAL DESCRIPTION
The
HYVIX-MAIN-R003, color-graphics
100 Pin TQFP
LCD controller board displays 320-by-240
dot graphics for 65K STN colors. A 16-bit
high-speed bus interface and external
high-
speed SRAM write function enable efficient
data transfers and high-speed rewriting of
data to the graphics RAM. The feature of
this product is less afterimage than old
product and possible 2 mode programming
