SEMICONDUCTOR TECHNICAL DATA
LCD Segment / Common Driver
With Controller
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.

This device contains circuitry to protect the inputs
against damage due to high static voltages or elec-
tric fields; however, it is advised that normal precau-
tions to be taken to avoid application of any voltage
higher than maximum rated voltages to this high
impedance circuit. For proper operation it is recom-
mended that V and V
out
be constrained to the
in
range V

< or = (V

or V

) < or = V
D D
. Reliability
of operation is enhanced if unused input are con-
nected to an appropriate logic voltage level (e.g.,
either V

o r V
DD
). Unused outputs must be left
open. This device may be light sensitive. Caution
should be taken to avoid exposure of this device to
any light source during normal operation. This
device is not radiation protected.
* Maximum Ratings are those values beyond which damage to the device may occur. Functional
operation should be restricted to the limits in the Electrical Characteristics tables or Pin Descrip-
tion section.
