Solomon Systech SSD1805
SSD1805 is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system. 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.GENERAL DESCRIPTION
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. 2FEATURES
