M66004SP/FP

16-DIGIT 5X7-SEGMENT VFD CONTROLLER

PIN DESCRIPTIONS

Symbol Pin name

Function

RESET Reset input This pin is used to initialize the internal state of the M66004.

CS

Chip select In “L” state, communication with the MCU is possible.

input

In “H” state, any instruction from the MCU is neglected.

SCK

Shift clock

input

At the rising edge from “L” to “H”, input data is shifted.

SDATA

Serial data

input

Character code or command data to display is input from MSB.

XIN,

XOUT

Clock input

Clock output

This pin is used to connect a resistor and a capacitor externally to set oscillation frequency. (maximum

oscillation frequency fosc(max)=1MHz) An external clock can be also connected. In this case, an external

clock is connected to pin XIN, and pin XOUT is set to be in open state.

DIG00~

DIG15

Digit output

These pins are used to connect to digit pins of VFD. Pins from DIG00 to DIG15 correspond to digits of VFD

from the first digit to the 16th digit.

SEG00~ Segment

SEG35 output

These pins are used to connect to segment pins of VFD. Pins from SEG00 to SEG35 correspond to segment

pins of VFD as shown in the table below.

P0, P1

Output port (static operation)

VCC1

Positive power supply for internal logic

VCC2

Positive power supply for high-pressure-resistant output port

VSS

GND

VP

Negative power supply for VFD drive

(Connection of segment output pins)

Each in the table shows one-dot segment and each figure

in shows the output segment pin number (from 00 to 35) to

connect.
