LCD Segment/ Common 4 G/S Driver with Controller

SSD1857 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic display system. SSD1857 consists of 192 high voltage driving output pins for driving 96 Segments and 96 Commons.

SSD1857 display data directly from its internal 96x96x2 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. 

SSD1857 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, SSD1857 is suitable for any portable battery-driven applications requiring long operation period and compact size.
