SSD1801 Datasheet | Solomon Systech

DESCRIPTION SSD1801 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix character display system. It consists of 105 high voltage driving output pins for driving 80 Segments, 24 mons and 1 icon driving-mon. It can display 2 or 3 lines of 16 characters with 5x8 dots format. The double height character mode and line vertical scroll functions are supported. SSD1801 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 character 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/ mands are sent from general MCU through a software selectable 6800-/8080-series patible 4/ 8-bit Parallel Interface or Serial Peripheral Interface. SSD1801 embeds a DC-DC Converter, Voltage Regulator, Voltage divider and RC oscillator which reduce the number of external ponents. With the special design on minimizing power consumption and die size, SSD1801 is suitable for portable battery-driven applications requiring a long operation period and a pact size.
