Advanced Information


130 x 130 STN

LCD Segment/ Common 4G/S and Mono Driver with Controller


SSD1848C is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1848C consists of 260 high-voltage driving output pins for driving maximum 130 Segments, 130 Commons.


SSD1848C 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.


SSD1848C 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, SSD1848C is suitable for any portable battery-driven applications requiring long operation period with compact size.
