1 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.
SSD1805 consists of 132 x 68 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from
common MCU through 8-bit 6800-series / 8080-series compatible Parallel Interface or 4-wires Serial
Peripheral Interface by software program selections.
SSD1805 embeds DC-DC Converter, On-Chip Oscillator and Bias Divider to reduce the number of external
components. With the advance design, low power consumption, stable LCD operating voltage and flexible die
package layout, SSD1805 is suitable for any portable battery-driven applications requiring long operation
period with compact size.
