LC75710NE

Dot Matrix VFD Display Controller/Driver

SANYO -> Panasonic 

LC75710NE, 75711NE, 75712E

Usage Notes

1. Power supply sequence

The sequences shown below must be followed when turning the power supply on and off. (See Figure 1.)

Power on: Logic block power supply (VDD) on → Driver block power supply (VFL) on → Display on (by the

execution of a display on/off control instruction)

Power off: Display off (by the execution of a display on/off control instruction) → Driver block power supply (VFL)

off → Logic block power supply (VDD) off

2. Anode output pins

The anode output pins AM1 to AM35 are used as the anode outputs that form the 5 × 7 dot matrix due to output

current considerations. We recommend using the anode output pins AA1 to AA8 for other anode output functions.

If the anode waveform is distorted and the VFD glows slightly (smearing) due to the VFD panel used or wiring

considerations, try using a lower oscillator frequency. Refer to Figure 2 when determining the oscillator frequency.
