DESCRIPTION

The M66004 is a 16-digit 5Ã7-segment vacuum fluorescent

display (VFD) controller using the silicon gate CMOS tech-

nology.

It contains 160 ROM characters and 16 user-defined RAM

characters and receives display character codes and various

commands from MCU to control VFD.

FEATURES

â¢ Built in 5Ã7-dot segment character ROM

(160 characters based on JIS-C-6220. Customization is

possible.)

â¢ Built in character RAM for user definition (16 characters)

â¢ Display digit length can be changed. (from 9 to 16 digits)

â¢ One-digit display cycle setting can be changed. (2 cycles)

â¢ Dimmer is adjustable. (8 grades)

â¢ Cursor display ON or OFF is selectable. (SEG35 output)

â¢ Built in automatic display digit increment function

â¢ Auto increment of display digit

â¢ Built in simultaneous all-digit display ON/OFF command

â¢ Connection to MCU by three signal lines, CS, SCK and

SDATA

â¢ Instruction execution with one byte*

â¢ 2 general purpose output ports

â¢ Positive supply voltage VCC=5V Â± 10%

â¢ Pull-down voltage VP=VCC-40V typ.

VCC-45V max. (peak)

*: Except for character RAM setting

APPLICATION

AV equipments, vacuum fluorescent display controller for

POS system, etc.

FUNCTION

The M66004 is a 16-digit 5Ã7-segment VFD (Vacuum Fluo-

rescent Display) controller and contains 160 ROM characters

based on JIS-C-6220 which can be customized and 16 RAM

characters that user can define freely.

Character display codes and various commands are re-

ceived as 8-bit serial data from MCU.

Main functions of this IC are display digit length setting, one-

digit display cycle setting and dimmer adjustment.

It has 36 segment output pins from SEG00 to SEG35 and

uses 35 pins from SEG00 to SEG34 for character display.

SEG35 output, which is independent of other segment, is

used for cursor display by inputting either cursor ON or OFF

command.

Once display data is fixed, display continues automatically

until new data is input. Therefore, MCU can execute other

jobs and is lightened of its load.

Additionally, the IC can control other I/O elements because it

contains two static operation output ports.
