6 / 18 page Pin Functions Note: The LC75834JE do not have the S9, S18, S27, S34 output pins. No. 5597-6/18 LC75834E, 75834W, 75834JE CE: Chip enable CL: Synchronization clock DI: Transfer data H — S1/P1 to S8/P8 S9 to S34 Pin 1 to 8 9 to 34 LC75834E, 75834W LC75834JE 1 to 8 9 to 30 — O Open 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. COM1 COM2 COM3 COM4 35 36 37 38 31 32 33 34 — O Open Common driver outputs. The frame frequency fO is given by: fO = (fOSC/512) Hz. OSC 44 40 CE CL DI 46 47 48 42 43 44 Serial data transfer inputs. These pins are connected to the control microprocessor. — I/O VDD I GND Oscillator connection An oscillator circuit is formed by connecting an external resistor and capacitor VLCD1 41 37 — I Open 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. VLCD2 42 38 — I Open 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. VDD 39 35 — — — Logic block power supply. Provide a voltage in the range 2.7 to 6.0 V. VLCD 40 36 — — — LCD driver block power supply. Provide a voltage in the range 2.7 to 6.0 V. VSS 43 39 — — — Ground pin. Connect to ground. INH 45 41 L I GND Display off control input •INH = low (VSS): Off S1/P1 to S8/P8 = Low (These pins are forcible set to the segment output port function and fixed at the VSS level.) S9 to S34 = Low (VSS), COM1 to COM4 = Low (VSS) •INH = high (VDD): On Note that serial data transfers can be performed when the display is forced off by this pin. Active I/O Handling when unused Function Pin No. |
