General Description

SSD1854 is a single-chip CMOS 4 gray scale LCD driver with controller for liquid crystal dot-matrix

graphic display system. It consists of 288 high voltage driving output pins for driving maximum 128

Segments and 160 Commons, customized for 2-sides COF modules.

SSD1854 displays data directly from its internal 128x176x2 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.

SSD1854 designed with multi-line-addressing (MLA) scheme to improve the display quality and

reduce the system power consumption.

SSD1854 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, SSD1854 is suitable for any portable battery-

driven applications requiring a long operation period and a compact size.
