Function
VSSA
-
1
Analog ground. This ground pin is used to internal analog circuitry.
VCO
I/O
2
Voltage Control Oscillator. This pin is used to control the internal oscillator
frequency by DC voltage input from external low pass filter.
RP
I/O
3
Bias Resistor. The bias resistor is used to regulate the appropriate bias
current for internal oscillator to resonate at specific dot frequency.
VDDA
-
4
Analog power supply. Positive 5 V DC supply for internal analog circuitry.
And a 0.1uF decoupling capacitor should be connected across to VDDA and
VSSA.
HFLB
I
5
Horizontal input. This pin is used to input the horizontal synchronizing
signal. It has an internal 100 k
Ω
pull-up resistor.
SSB
I
6
Serial interface enable. It is used to enable the serial data interface and is
also used to select I²C or SPI bus operation. If this pin is left floating, I²C bus
is enable. Otherwise the SPI bus is enabled.
SDA
I
7
Serial data input. The external data transfer through this pin to internal
display registers and control registers. It has an internal 100 k
Ω
pull-up
resistor.
SCK
I
8
Serial clock input. The clock input pin is used to synchronize the data
transfer. It has an internal 100 k
Ω
pull-up resistor.
VDD
-
9
Digital pow er supply. Positive 5 V DC supply for internal digital circuitry
and a 0.1uF decoupling capacitor should be connected across to VDD and
VSS.
VFLB
I
10
Vertical input. This pin is used to input the vertical synchronizing signal. It
has an internal pull-up resistor.
HTONE
O
11
Half tone output. This pin is used to attenuate the external R, G, B amplifiers
gain for the transparent windowing effect.
FBKG
O
12
Fast Blanking output. It is used to cut off the external R, G, B signals while
this chip is displaying characters or windows.
BOUT
O
13
Blue color output. It is a blue color video signal output.
GOUT
O
14
Green color output. It is a green color video signal output.
ROUT
O
15
Red color output. It is a red color video signal output.
VSS
-
16
Digital ground. This ground pin of internal digital circuitry.
