LCD Segment / Common COLOR Driver with Controller

SSD1772 is a single-chip CMOS color STN LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1772 consists of 393 high voltage driving output pins for driving maximum 104 RGB Segments, 81 Commons CSTN panel. 

SSD1772 consists of 104 RGB x 81 x 16 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from common MCU through 8-bit 6800-series / 8080-series compatible Parallel Interface or 3-wires / 4- wires Serial Peripheral Interface by pins selection.

SSD1772 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, SSD1772 is suitable for any portable battery-driven applications requiring long operation period with compact size.
