SSD1818A
1. GENERAL DESCRIPTION
SSD1818A is a single-chip CMOS LCD driver with controllers for dot-matrix graphic liquid crystal
display system. It consists of 169 high-voltage driving outputs for driving maximum 104 Segments, 64
Commons and 1 icon line.
SSD1818A consists of 104 x 65 bits Graphic Display Data RAM (GDDRAM). Data/Commands
are sent from common MCU through 8-bit Parallel or 4-wire Serial Interface. 6800-series, 8080-series
compatible Parallel Interface and Serial Peripheral Interface can be selected by hardware configuration.
SSD1818A embeds DC-DC Converter with booster capacitors, On-Chip Oscillator and Bias
Divider so as to reduce the number of external components. With the advanced design for low power
consumption, stable LCD operating voltage and flexible die layout, SSD1818A is suitable for any portable
battery-driven applications requiring long operation period with compact size.
