CMOS

SSD1820A/21 is a single-chip CMOS LCD driver with controller for a liquid crystal

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.

SSD1820A/21 displays data directly from its internal 128x65/128X81 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.

SSD1820A/21 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/pack-

age layout, SSD1820A/21 is suitable for any portable battery-driven applications re-

quiring a long operation period and a compact size.
