LCD Segment/ Common 4 G/S Driver with Controller

SSD1856 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic display system. SSD1856 consists of 185 high voltage driving output pins for driving 104 Segments and 80 Commons and 1 icon line.

SSD1856 display data directly from its internal 104x81x2 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from general MCU through hardware selectable 6800-/8080- series compatible Parallel Interface or 3/4 wires Serial Peripheral Interface. 

SSD1856 embeds a DC-DC Converter, a LCD Voltage Regulator, an On-Chip Bias Divider, integrated bias capacitors, integrated booster capacitors and an On-Chip Oscillator, which reduce the number of external components. With the special design on minimizing power consumption and die/package layout, SSD1856 is suitable for any portable battery-driven applications requiring long operation period and compact size.
