LCD Segment / Common Driver with Controller
for Character Display System
CMOS
GENERAL DESCRIPTION
system. It consists of 105 high voltage driving output pins for driving 80 Segments, 24 Commons and 1 icon
driving-Common. 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.
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/ Commands are sent
from general MCU through a software selectable 6800-/8080-series compatible 4/ 8-bit Parallel Interface or Serial
Peripheral Interface.
the number of external components. 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 compact
size.
