8 / 29 page LC75890W No.A1971-8/29 Continued from preceding page. Symbol Pin No. Function Active I/O Handling when unused INH 45 Display off control input • INH = low (VSS) ...Display forced off S1/P1 to S12/P12=low (VSS) (These pins are forcibly set to the general-purpose output port function and held at the VSS level.) S13 to S36=low (VSS) COM1 to COM4=low (VSS) S37/OSCI=low (VSS) (This pin is forcibly set to the segment output port function and held at the VSS level.) LCD drive bias voltage stabilization circuit stopped. Stops the internal oscillator. Inhibits external clock input. • INH = high (VDD) ...Display on LCD drive bias voltage stabilization circuit is enabled. Enables the internal oscillator circuit. (Internal oscillator operating mode) Enables external clock input. (External clock operating mode) However, serial data transfer is possible when the display is forced off. L I GND VDD 42 Logic block power supply pin. A power voltage of 2.7 to 3.6V must be applied to this pin. - - - VLCD 43 LCD driver block power supply pin. A power voltage of 2.7 to 5.5V must be applied to this pin. - - - VSS 44 Ground pin. Must be connected to ground. - - - |
