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

SSD1797 is a single-chip CMOS color STN LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1797 consists of 522 high voltage driving output pins for driving maximum 130 RGB Segments, 132 Commons CSTN panel.

SSD1797 consists of 130 RGB x 132 x 16 bits Graphic Display Data RAM (GDDRAM). Data/Commands are send 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.

SSD1797 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, SSD1797 is suitable for any portable battery-driven applications requiring long operation period with compact size.
