VOLTAGE OUTPUTS
: These outputs drive all 240 pixel
inputs of the LCD simultaneously after the high-to-low tran-
sition of LP. Outputs are high impedance while LP is high.

DATA
: The Data inputs consist of 6-bit words for each of
three channels. At the falling edge of DCLK, three 6-bit
words for three adjacent channels are loaded in parallel.
Each data bit is represented as Dij where:
i = 2-0 indicates the channel
j = 5-0 indicates the significance of the bit in each word.
D
i5
indicates the MSB and D
i0
indicates the LSB of the input
word.
LP
34
I
Latch Pulse
: When LP is asserted, the data is transferred
from the Input Register into the Storage Register, and the
selected analog voltages drive the LCD. Also, the EIOx#
output is reset to the ‘high’ level.
DCLK
15
I
DATA CLOCK
: Data is loaded into the input registers on the
high-to-low transition of DCLK for 2xCLK= low and on both
rising and falling edges of DCLK for 2xCLK = high.
CLAMP#
30
I
CLAMP
: The CLAMP# input controls the active pulldown
devices which are present on the DCLK and D
00
-D
25
inputs.
When the CLAMP# signal drives low, these clamp devices
connect DCLK and D
00
-D
25
to the WFP6530B’s GND
through a low impedance.
The CLAMP# pin should be
connected to V
DDD
in applications where level shifting
is not used (i.e. when V
COM
modulation is employed).

DIGITAL SUPPLY VOLTAGE
: Either 3.3 V or 5.0 V should
be provided on this pin to supply digital power to the device.

REFERENCE ANALOG VOLTAGE INPUTS:
These
nine inputs are used to supply the adjustable-reference volt-
age inputs to the resistive-string DAC to provide the trans-
missivity-voltage response required for each type of LCD.
Note: both V

pads must be connected to each other
and to the same potential; also, both V
0
pads must be .
connected to each other and to the same potential
