Advance Information
100 x 34 STN
LCD Segment/ Common Mono Driver with Controller
CMOS
SSD1803 is a single-chip CMOS LCD driver with controller for liquid crystal dot-matrix character display system. It consists of 134 high voltage driving output pins for driving 100 Segments, 34 Commons. It can display 1, 2 or 4 lines with 5x8 or 6x8 dots format.
SSD1803 displays character directly from its internal 9,600 bits (240 characters x 5 x 8 dots) Character Generator ROM (CGROM). All the character codes are stored in the 640 bits (80 characters) Data Display RAM (DDRAM). User defined character can be loaded via 512 bits (8 characters) Character Generator RAM (CGRAM). In addition, there is a 128 bits Icon RAM for Icon display. Data/ Commands are sent from general MCU through software selectable 4/ 8-bit Parallel Interface or Serial Peripheral Interface.
SSD1803A embeds a DC-DC Converter and oscillator which reduce the number of external components. With the special design on minimizing power consumption and die size, SSD1803 is suitable for portable battery-driven applications requiring a long operation period and a compact size.
