Sample Application Circuit
Usage Notes
1. Segment and digit waveforms
Figure 5
The segment waveform is distorted by the wiring of the VFD panel used, and furthermore, in the case of being used
with essentially no dimming as in the digit waveform 1, as shown in Figure 5, the VFD panel glow dimly. By
carefully considering the segment waveform, it can be seen that this problem can be resolved by applying an
adequate amount of dimming, as shown in digit waveform 2. When f
OSC
is 1.6 [MHz], we recommend using 10 bits
of dimmer data in the range 000
H
to 3E0
H
.
2. Serial data transfer
Since display data is transferred in two operations as shown in Figure 2, we recommend that all display data be
transferred within 30 [ms] to prevent degradation of the visual quality of the displayed image.
