Advance Information
LCD Segment / Common Driver
with Controller
CMOS
dot-matrix graphic display system. SSD1820A consists of 194 high voltage driving out-
put pins for driving 128 Segments, 64 Commons and 2 icon driving Commons, while
SSD1821 consists of 210 high voltage driving output pins for driving 128 Segments,
80 Commons and 2 icon driving Commons.
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.
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/pack-
age layout, SSD1820A/21 is suitable for any portable battery-driven applications re-
quiring a long operation period and a compact size.
