STANDARD NAME 5 REV.NO PAGE 00 9 of 12 M0220MD-202LDAR2 Function Descriptions The anode and grid data is clocked into the module using a synchronous serial interface. The refresh rate should be at least 60HZ (100HZ IS RECOMMANDED). The sequence That this data should be sent to the module is as follows: Clock in the anode data Clock in the grid data Latch the anode and grid data Disable the clear signal Enable the clear signal A minimum of 36 anode data bits should be sent to the module.The table below details the correlation between the anode bits clocked into the module and their TM bits is unused in the upper row Pixel position in the 5X7 characters. The 36 of characters and is the inverted triangel in the lower row. Additional bits can be clocked into the module if necessary. The module will only display the last 36 data bits.if, for example. 5 complete bytes of data are sent.the triangle will be the last bit of byte 5. and the first 4 bits of byte 1 will not be displayed. At any point in time only 1 grid should be active.this active bit can be propagated through the display by clocking in low GRID DATA bits for the other position. For example: send the anode data for character position 1.then clock in a high GRID DATA bit(using the LATCH CLK signal). To display a character at position 2,send the anode data then clck in a low GRID DATA bit.this can be continued to character position 40. The table below details the character position of the VFD.

M0220MD-202LDAR2 REV.NO PAGE 00 10 of 12 Operation Recommendations 6.1 Avoid applying excessive shock or vibration beyond the specification for the VFD module. 6.2 Since VFDs are made of glass material, careful handing is required,i.e. Direct impact with hard material to the glass surface (especially exhaust tip) may crack the glass. 6.3 When mounting the VFD module to you system,leave a slight gap between the VFD glass and your front panel. The module shoud be mounted without stress to avoid flexing of the PCB. 6.4 Avoid plugging or unplugging the interface connection with the power on ,otherwise it may cause the severe damage to input circuitry. 6.5 Slow starting power supply may cause non-operation because the chip mcu won t be reset. 6.6 Exceeding any of maximum ratings may cause the permanent damage. 6.7 Since the VFD modules contain high voltage source,careful handing is required while power is on 6.8 When the power is turned off,the capacitor does not discharge immediately. So the high voltage applied to VFD must not get in contact with ICs. In other words, short-circuit of mounted component on PCB within 30 seconds after power-off may cause damage the module. 6.9 The power supply must be capable of providing at least 3 times the rated current,because the surge current may be 3 times the specified current consumption when the power is turned on. 6.10 Avoid using the module where excessive noise interference is expected.Noise may affects the interface signal and causes improper operation. And it is important to keep the length of the interface cable less than 50cm. 6.11 Since all VFD modules contain C-MOS ICs,anti_static handling procedures are always required. STANDARD NAME 7 DOCUMENT NO.
