SSD1809
CMOS
SSD1809 is a single-chip CMOS LCD driver with controller for liquid
crystal dot-matrix graphic display system. It consists of 225 high voltage
driving output pins for driving 160 Segments, 64 Commons and 1icon driv-
ing-Common.

SSD1809 displays data directly from its internal Graphic RAM
(160x65). Data/Commands are sent from general MCU through a software
selectable 6800-/8080-series compatible Parallel Interface or Serial Periph-
eral Interface.
SSD1809 embeds a DC-DC Converter, 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 package layout,
SSD1809 is suitable for any portable battery-driven application requiring a
long operation period and a compact size.
