SSD1800

SSD1800 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix character display system. It consists of 97 high voltage driving output pins for driving 80 Segments, 16 Commons and 1 icon driving-Common. SSD1800 can display 2 lines of 16 characters with 5x8 dots format. The double height character mode and line vertical scroll functions are supported.

SSD1800 displays character directly from its internal 10,240 bits (256 characters x 5 x 8 dots) Character Generator ROM (CGROM). All the character codes are stored in the 512 bits (16 characters x 4 lines) Data Display RAM (DDRAM). User defined character can be loaded via 320 bits (8 characters x 5 x 8 dots) Character Generator RAM (CGRAM). In addition, there is a 80 bits Icon RAM for Icon display. Data/ Commands of SSD1800 are sent from general MCU through software selectable 6800-/8080-series compatible 4/ 8-bit Parallel Interface or Serial Peripheral Interface.

SSD1800 embeds a DC-DC Converter, Voltage Regulator, Voltage divider and RC oscillator that reduce the number of external components. With the special design on minimizing power consumption and die size, SSD1800 is suitable for portable battery-driven applications requiring a long operation period and a compact size.
