Also feasible to apply external clock. In this case,inject external clock to Xin terminal and open Xout terminal.Connect to digit terminal of VFD. DIG00~DIG15 correspond to the 1st figure to 16th figurerespectively.Connect to segment terminal of VFD. For corresponding SEG00~SEG35 to segmentterminal of VFD, refer to the figure right.Output port (static operation).Positive power supply terminal for internal logic.Positive power supply terminal for high tension output port.GND terminal.Negative power supply terminal for VFD drive.in the right figure indicates 1 dot of segment, the figure in shows the segment outputterminal number (00~35) to be connected.2114161520131817593331236412161DisplayControlRegisterChipSelectInputShiftClockInputSerialDataInputCSSCKSDATADisplayCodeRegister(8-bitx16)SerialReceptionCircuitcodewriteCode/CommandControlCircuitRAMwriteDecoderDecoderCGROM(35-bitx160)CGROM(35-bitx16)SegmentOutputCircuitSEGSEGSEGSEG00262735SegmentOutputOutputPort(2-bit)P0P1OutputPortResetInputRESETClockInputXINClockOutputXOUTClockGenerationCircuitcodeselectDisplayControllerDigitOutputCircuitDIGDIGDIGDIG00111215DigitOutput12345678910111213141516171819202122232425262728293031326463626160595857565554535251504948474645444342414039383736353433DIG11DIG10DIG09DIG08DIG07DIG06DIG05DIG04DIG03DIG02DIG01DIG00RESETCSSCKSDATAPIPOVcc1XoutXinVssSEG35SEG34SEG33SEG32SEG31SEG30SEG29SEG28SEG27VpSEG26SEG25SEG24SEG23SEG22SEG21SEG20SEG19SEG18SEG17SEG16SEG15SEG14SEG13SEG12SEG11SEG10SEG09SEG08SEG07SEG06SEG05SEG04SEG03SEG02SEG01SEG00Vcc2DIG15DIG14DIG13DIG1200 01 02 03 0405 06 07 08 0910 11 12 13 1415 16 17 18 1920 21 22 23 2425 26 27 28 2930 31 32 33 3435www . xiaoyu163. comQQ 376315150 992894298TEL 13942296513 992894298051513673QQTEL 13942296513 QQ 376315150 892498299TEL 13942296513 QQ 376315150 892498299http://www.xiaoyu163.comhttp://www.xiaoyu163.com
