Description

SEGA1 ~ SEGA35

VFD tube anode electrode drive output.

O Directly connected to fluorescent display tube and a pulldown resistor

SEGB1 ~ SEGB35

is not necessary. IOH > -5mA

COM1 ~ COM20

ADA, ADB

VDD

L-GND

VDISP

D-GND

TEST

DO

DA

CP

CS

RESET

OSC

VFD tube grid electrode drive output.

O Directly connected to fluorescent display tube and a pulldown resistor

is not necessary. IOH > -40mA

VFD tube anode electrode drive output.

O Directly connected to fluorescent display tube and a pulldown resistor

is not necessary. IOH > -15mA

VDD, L-GND are power supplies for internal logic.

-

VDISP, D-GND are power supplies for driving fluorescent tubes. Apply

VDISP after VDD is applied.

Use the same power supply for L-GND and D-GND.

Test mode control pin

I

“High” → Test mode enable

“Low” → Test mode disable

O Data output pin for testing purpose only

I

Serial data input (positive logic).

Input from LSB.

I

Shift clock input.

Serial data is shifted on the rising edge of CP.

I

Chip select input.

Serial data transfer is disabled when CS pin is “H” level.

Reset input.

“Low” initializes all the functions.

Initial status is as follows.

I

• Address of each RAM ...address “00”H

• Data of each RAM......... Content is undefined

• Display digit....................20 digits

• Brightness adjustment....0/1024

• All lights ON or OFF ......OFF mode

Oscillation connection

I/O An oscillator circuit is formed by connecting an external resistor and

capacitor at this pin. See Application circuit
