130 x 130 STN LCD Segment / Common 4G/S Driver with Controller

SSD1848 is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1848 consists of 260 high-voltage driving output pins for driving maximum 130 Segments, 130 Commons.

SSD1848 consists of 130 x 130 x 2 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 software program selections.

SSD1848 embeds DC-DC Converter, On-Chip Oscillator and Bias Divider to reduce the number of external components. With the advance design, low power consumption, stable LCD operating voltage and flexible die package layout, SSD1848 is suitable for any portable battery-driven applications requiring long operation period with compact size.
