132RGB x 160CSTN
LCD Segment / Common COLOR Driver with Controller

SSD1793 is a single-chip CMOS color STN LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1793 consists of 556 high voltage driving output pins for driving maximum 132 RGB Segments, 160 Commons CSTN panel. 

SSD1793 consists of 132 RGB x 162 x 18 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from common MCU through 16-bit/8-bit 6800-series/8080-series compatible Parallel Interface or 3-wires/4-wires Serial Peripheral Interface by pins selection.

SSD1793 embeds On-Chip Oscillator, DC-DC Converter, bias divider so as to reduce the number of external component. With the advanced design, low power consumption, stable LCD operating voltage and flexible die package layout, SSD1793 is suitable for any portable battery-driven applications requiring long operation period with compact size.
