Advanced Information
LCD Segment / Common Driver with Controller
CMOS
1 General
Description
SSD1828 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix graphic display system.
SSD1828 consists of 162 high voltage driving output pins for driving 96 Segments, 64 Commons and 1 icon driving
with dual Common outputs.


SSD1828 displays data directly from its internal 96x65 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.

SSD1828 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
layout, SSD1828 is suitable for any portable battery-driven applications requiring a long operation period and a
compact size.
