CMOS

LCD Segment / Common Driver with Controller

SSD1850/51 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic

display system. SSD1850 consists of 194 high voltage driving output pins for driving 128 Segments and
64 Commons and 1 icon line. SSD1851 consists of 210 high voltage driving output pins for driving 128
Segments and 80 Commons and 1 icon line.

SSD1850/51 display data directly from their internal 128x65x2 / 128x81x2 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.

SSD1850/51 embeds a DC-DC Converter, a LCD Voltage Regulator, an On-Chip Bias Divider

and an On-Chip Oscillator which reduce the number of external components. With the special design on
minimizing power consumption and die/package layout, SSD1850/51 is suitable for any portable battery-
driven applications requiring long operation period and compact size.
