General Description
SSD1805 is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1805 consists of 200 high-voltage driving output pins for driving maximum 132 Segments, 68 Commons / 132 Segments, 64 Commons and 1 icon-driving Common / 132 Segments, 54 Commons and 1 icon-driving Common / 132 Segments, 32 Commons and 1 icon-driving Common. SSD1805 can also be switched among 32, 54, 64 or 68 display multiplex ratios by hardware pin selection.
