GENERAL DESCRIPTION
The OM6206 is a low-power CMOS LCD controller and
driver, designed to drive a graphic display of 65 rows and
102 columns. All necessary functions for the display are
provided in a single chip, including on-chip generation of
LCD supply and bias voltages, resulting in a minimum of
external components and low power consumption.
The OM6206 interfaces to microcontrollers via a serial bus
interface.

Pin functions
6.1.1
R0
TO
R64:
ROW DRIVER OUTPUTS
These pins output the row signals.
6.1.2
C0
TO
C101:
COLUMN DRIVER OUTPUTS
These pins output the column signals.
6.1.3
V
SS1
AND
V
SS2
:
GROUND SUPPLY RAILS
The supply rails V
SS1
and V
SS2
must be connected
together.
6.1.4
V
DD1
, V
DD2
AND
V
DD3
:
SUPPLY VOLTAGE RAILS
V
DD2
and V
DD3
are the supply voltage for the internal
voltage generator. Both have the same voltage and should
be connected together outside the chip. V
DD1
is used as
supply voltage for the rest of the chip. V
DD1
can be
connected together with V
DD2
and V
DD3
but in this case
care must be taken to respect the supply voltage range
(see Chapter 11).
If the internal voltage generator is not used the pins
V
DD2
and V
DD3
must be connected to pin V
DD1
or
connected to the supply voltage.
6.1.5
V
LCDIN
: LCD
SUPPLY VOLTAGE
Positive supply voltage for the liquid crystal display. An
external LCD supply voltage can be supplied using
pin V
LCDIN
. In this case, V
LCDOUT
has to be left open and
the internal voltage generator has to be programmed to
zero. If the OM6206 is in Power-down mode, the external
LCD supply voltage has to be switched off.
6.1.6
V
LCDOUT
:
VOLTAGE MULTIPLIER OUTPUT
Positive supply voltage for the liquid crystal display. If the
internal voltage generator is used, the two supply rails
V
LCDIN
and V
LCDOUT
must be connected together. If an
external supply is used this pin must be left open.
6.1.7
V
LCDSENSE
:
VOLTAGE MULTIPLIER REGULATION
INPUT
V
LCDSENSE
is the input of the internal voltage multiplier
regulation.
If the internal voltage generator is used then V
LCDSENSE
must be connected to V
LCDOUT
. If an external supply
voltage is used then V
LCDSENSE
can be left open or
connected to ground.
6.1.8

TEST PINS
T1, T3, T4 and T5 must be connected to V

, T2 must be
left open. Not accessible to user.
