16-DIGIT 5×7-SEGMENT VFD CONTROLLER

DESCRIPTION OF FUNCTION

1. Display digit length setting

The display digit length can be set within the range from 9-

digit to 16-digit according to the number of digits of VFD.

In case that the display digit length is set to 12 when a 16-

digit VFD is used, digits from 13 to 16 are displayed as blank.

2. Dimmer value and one-digit display frequency (Tdsp)

setting

Regarding dimmer value, 8-stage setting is possible. One-

digit display scan time (Tdsp) can be set to either Tdsp=128/

fOSC or Tdsp=256/fOSC.

Scan cycle time T is set to T=Tdsp × N (N: display digit

length).

Ex. fOSC=455kHz, N=16

Tdsp=281µs, T=4.5ms (222Hz) or Tdsp=562µs, T=9.0ms (111Hz)
