Segment outputs for displaying the display data transferred by serial data
input. The pins S1/P1 to S8/P8 can be used as general-purpose output
ports when so set up by the control data.
Common driver outputs.
The frame frequency is fO Hz.
The COM4/S87 pin can be used as a segment output in 1/3 duty.
Oscillator connection.
An oscillator circuit is formed by connecting an external resistor and
capacitor to this pin.
Serial data transfer inputs. These pins are connected to the control
microprocessor.
CE: Chip enable
CL: Synchronization clock
DI: Transfer data
Display off control input
• INH = low (VSS) ....Off
S1/P1 to S8/P8 = low (VSS)
(These pins are forcibly set to the segment output port
function and fixed at the VSS level.)
S9 to S86 = low (VSS)
COM1 to COM3 = low (VSS)
COM4/S87 = low (VSS)
• INH = high (VDD) ..On
Note that serial data transfers can be performed when the display is forced
off by this pin.
Used to apply the LCD drive 2/3 bias voltage externally. This pin must be
connected to VLCD2 when 1/2 bias drive is used.
Used to apply the LCD drive 1/3 bias voltage externally. This pin must be
connected to VLCD1 when 1/2 bias drive is used.
Logic block power supply. Provide a voltage in the range 2.7 to 6.0 V.
LCD driver block power supply. Provide a voltage in the range 2.7 to 6.0 V.
