Description
CSR
The input pin to select the transfer direction of the common signal output data.
At 1/n duty, data is transferred from COM1 to COMn when “L” is applied to this pin and
transferred from COMn to COM1 when “H” is applied to this pin.
SSR
The input pin to select the transfer direction of the segment signal output data.
“L”: Data transfer from SEG
1 to SEG120
“H”: Data transfer from SEG
120 to SEG1
V
1 , V2, V3A, V3B, V4
The pins to output bias voltages to the LCD.
For 1/4 bias : The V
2 and V3B pins are shorted.
For 1/5 bias : The V
3A and V3B pins are shorted.
BEB
The input pin to enable or disable the voltage multiplier circuit.
"L" disables the voltage multiplier circuit. "H" enables the voltage multiplier circuit.
The voltage multiplier circuit doubles the input voltage V
MUL and the multiplied voltage
referenced to V
DD is output to the V5IN pin. The voltage multiplier circuit can be used
only when generating a level lower than GND.
V
IN
The pin to input voltage to the voltage multiplier.
V
5, V5IN
The pins to supply the LCD drive voltage.
The LCD drive voltage is supplied to the V
5 pin when the voltage multiplier is not used
(BEB = 0) and the internal contrast adjusting circuit is also not used. At this time, the
V
5IN pin should be open.
The LCD drive voltage is supplied to the V
5IN pin when the voltage multiplier is not used
(BEB = 0) but the internal contrast adjusting circuit is used. At this time, the V
5 pin
should be open.
When the voltage multiplier is used (BEB = 1), the V
5 pin should be open (the
multiplied voltage is output to the V
5IN pin). In this case, the internal contrast adjusting
circuit must be used. Capacitors for the voltage multiplier should be connected
between the V
DD pin and the V5IN pin.
V
C
The pin to connect the positive pin of the capacitor for the voltage multiplier.
V
CC
The pin to connect the negative pin of the capacitor used for the voltage multiplier.
