16-DIGIT 5X7-SEGMENT VFD CONTROLLER
Function
This pin is used to initialize the internal state of the M66004.
In “L” state, communication with the MCU is possible.
In “H” state, any instruction from the MCU is neglected.
At the rising edge from “L” to “H”, input data is shifted.
Character code or command data to display is input from MSB.
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 X
IN
, and pin X
OUT
is set to be in open state.
These pins are used to connect to digit pins of VFD. Pins from DIG
00
to DIG
15
correspond to digits of VFD
from the first digit to the 16th digit.
These pins are used to connect to segment pins of VFD. Pins from SEG
00
to SEG
35
correspond to segment
pins of VFD as shown in the table below.
Output port (static operation)
Positive power supply for internal logic
Positive power supply for high-pressure-resistant output port
GND
Negative power supply for VFD drive

PIN DESCRIPTIONS
(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.
