Connect to ground. — — — Pin Functions Segment outputs for displaying the display data transferred by serial data input. The S1/P1 to S4/P4 pins can be used as general-purpose output ports under serial data control. Common driver outputs The frame frequency fo is given by : fo = (fOSC/384)Hz. Key scan outputs Although normal key scan timing lines require diodes to be inserted in the timing lines to prevent shorts, since these outputs are unbalanced CMOS transistor outputs, these outputs will not be damaged by shorting when these outputs are used to form a key matrix. The KS1/S24 and KS2/S25 pins can be used as segment outputs when so specified by the control data. Key scan inputs These pins have built-in pull-down resistors. Oscillator connection An oscillator circuit is formed by connecting an external resistor and capacitor at this pin. Serial data interface connections to the controller. Note that DO, being an open-drain output, requires a pull-up resistor. CE :Chip enable CL :Synchronization clock DI :Transfer data DO :Output data v Used for applying the LCD drive 2/3 bias voltage externally. Must be connected to VLCD2 when a 1/2 bias drive scheme is used. Used for applying the LCD drive 1/3 bias voltage externally. Must be connected to VLCD1 when a 1/2 bias drive scheme is used. Logic block power supply connection. Provide a voltage of between 4.5 and 6.0V. LCD driver block power supply connection. Provide a voltage of between VDD–0.5 and 6.0V. |
