General Description

SSD1858 is a single-chip CMOS 4 gray scale LCD driver with controller for liquid crystal dot-matrix

graphic display system. SSD1858 consists of 169 high voltage driving output pins for driving maximum

104 Segments, 64 Commons and 1 icon driving Commons. SSD1858 supports two display modes 96x65

or 104x65 by pin select.

SSD1858 displays data directly from its internal 104x65x2 bits Graphic Display Data RAM

(GDDRAM). Data/Commands are sent from general MCU through a hardware selectable 6800-/8080-

series compatible Parallel Interface or 3/4 wires Serial Peripheral Interface.

SSD1858 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, SSD1858 is suitable for any portable battery-driven applications requiring a long

operation period and a compact size.
