Pin Functions
Power Supply
V
CC
, GND:
Supply power to the internal logic circuits.
VLCD, GND:
Supply power to the LCD drive circuits (Figure 1).
V1L, V1R, V2L, V2R, V5L, V5R, V6L, V6R:
Supply different power levels to drive the LCD. V1 and
V2 are selected levels, and V5 and V6 are non-selected levels.
Control Signals
CL:
Inputs data shift clock pulses for the shift register. At the falling edge of each CL pulse, the shift
register shifts data input via the DIO pins.
M:
Changes the LCD drive outputs to AC.
CH:
Selects the data shift mode. (CH = high: 2
×
80-output mode, CH = low: 160-output mode)
SHL:
Selects the data shift direction for the shift register and the common signal scan direction (Figure 2).
DIO1, DIO2:
Input or output data. DIO1 is input and DIO2 is output when SHL is high. DIO1 is output
and DIO2 is input when SHL is low.
DI:
Input data. DI is input to X81–X160 when CH and SHL are high, and to X81–X1 when SHL is low.
DISPOFF
:
Controls LCD output level. A low
DISPOFF
sets the LCD drive outputs X1–X160 to the V2
level. A high
DISPOFF
is normally used.
LCD Drive Outputs
X1–X160:
Each X outputs one of four voltage levels V1, V2, V5, or V6, depending on the combination of
the M signal and the data level (Figure 3).
