ST7565Pin Name I/O Function No. of PinsCLSITerminal to select whether or enable or disable the display clock internaloscillator circuit.CLS = “H” : used Internal oscillator circuit .CLS = “L” : used external clock input .(internal oscillator is disable)When CLS = “L”, input the display clock through the CL terminal.1M/SIThis pin set to VDD1This is the display clock input terminalThe following is true depending on the M/S and CLS status.M/S CLS CLCLI/O“H”“L”“H”“L”“H”“L”OutputInputInputInput1FROThis is the liquid crystal alternating current signal terminal.1DOFFRSIRSOOIThis is the LCD blanking control terminal.This is the output terminal for the static drive.This terminal is only enabled when the static indicator display is ONand is used in conjunction with the FR terminal.This terminal selects the resistors for the V5 voltage level adjustment.IRS = “H”: Use the internal resistorsIRS = “L”: Do not use the internal resistors. The V5 voltage level isregulated by an external resistive voltage divider attached to the VR terminal111HPMIThis is the power control terminal for the power supply circuit for liquid crystaldrive.HPM = “H”: Normal modeHPM = “L”: High power mode1These pins are DUTY selection.SEL 3 , 2 , 1 DUTY BIAS0 , 0 , 0 1/65 1/9 or 1/7SEL3SEL2SEL1I0 , 0 , 1 1/49 1/8 or 1/60 , 1 , 0 1/33 1/6 or 1/50 , 1 , 1 1/55 1/8 or 1/631 , 0 , 0 1/53 1/8 or 1/61, X , X ----- -----TEST1 ~ 10IThese are terminals for IC testing .They are set to open .10Ver 0.9 10/10 2001/01/11
