LCD Segment / Common Driver with Controller

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 output 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/package layout, SSD1820A/21 is suitable for any portable battery-driven applications requiring a long operation period and a compact size.
