6.2.2 Parallel interface timing

TDWR = Normal command mode: Min 1μS

Graphic DMA Mode: Min 15μS

*RDY=0(BUSY) is output every 1 byte.

This module has 256 bytes of receiving buffer internally, and after data is inputted, RDY

signal is set to RDY=0(BUSY) until it is stored into the receiving buffer.

If data is inputted when receiving buffer is full, RDY signal is set to RDY=0(BUSY) until

space for 1 byte will be available in receiving buffer.

It changes, and is variable depending on the command contents, or data writing frequency at user

side.

Due to above reason, RDY line should be always checked for data writing.

Notice for the Cautious Handling VFD Modules

Handling and Usage Precautions:

Please carefully follow the appropriate product application notes for proper usage, safety handling, and operation standards for

maximum performance.

[VFD tubes are made of glass]

• Because the edges of the VFD glass-envelop are not smooth, it is necessary to handle carefully to avoid injuries to

your hands

• Please avoid breaking the VFD glass-envelop to prevent injury from sharp glass particles.

• The tip of the exhaust pipe is fragile so avoid shock from impact.

• It is recommended to allow sufficient open space surrounding the exhaust pipe to avoid possible damage.

• Please design the PCB for the VFD-module within 0.3 mm warping tolerance to avoid any forces that may damage

the display due to PCB distortion causing a breakdown of the electrical circuit leading to VFD failure.

[High voltage]

• Avoid touching conductive electrical parts, because the VFD-module uses high voltage exceeding 30～100 volts.

• Even when electric power is turned off, it may take more than one minute for the electrical current to discharge.

[Cable connection]

• Do not unplug the power and/or data cables of VFD-modules during operating condition because unrecoverable

damage may result.

• Sending input signals to the VFD-module during a power off condition sometimes causes I/O port damage.

• It is recommended to use a 30 cm or shorter signal cable to prevent functional failures.

[Electrostatic charge]

• VFD-modules need electrostatic free packaging and protection from electrostatic charges during handling and

usage.

[Structure]

• During operation, VFD and VFD-modules generate heat. Please consider sufficient heat radiation dissipation using

heat sink solutions.

• We prefer to use UL grade materials or components in conjunction with VFD-modules.

• Wrap and twist motion causes stress and may break VFDs & VFD modules. Please adhere to allowances within

0.3mm at the point of attachment.

[Power]

• Apply regulated power to the VFD-module within specified voltages to protect from failures.

• Because some VFD-modules may consume in rush current equal to twice the typical current at power-on timing,

we recommend using a sufficient power capability and quick starting of the power regulator.

• VFD-module needs a specified voltage at the point of connection. Please use an adequate power cable to avoid a

decrease in voltage. We also recommend inserting a power fuse for extra protection.

[Operating consideration]

• Illuminating phosphor will decrease in brightness during extended operation. If a fixed pattern illuminates for an

extended period,( several hours), the phosphor efficiency will decrease compared to the non operating phosphor

causing a non uniform brightness among pixels. Please consider programming the display patterns to use all

phosphor segments evenly. Scrolling may be a consideration for a period of time to refresh the phosphor condition

and improve even illumination to the pixels.

• We recommend using a signal cable 30cm or less to avoid some possible disturbances to the signal.

[Storage and operating environment]

• Please use VFD-modules under the recommended specified environmental conditions. Salty, sulfur and dusty

environments may damage the VFD-module even during storage.

[Discard]

• Some VFDs contain a small amount of cadmium in the phosphor and lead in the solder. When discarding VFDs or

VFD-modules, please adhere to governmental related laws or regulations.

[Others]

• Although the VFD-module is designed to be protected from electrical noise, please plan your circuitry to exclude as

much noise as possible.

• Do not reconstruct or repair the VFD-module without our authorization. We cannot assure the quality or reliability of

unauthorized reconstructed VFD-modules.

Notice:

･We do not authorize the use of any patents that may be inherent in these specifications.

･Neither whole nor partial copying of these specifications are permitted without our approval.

If necessary , please ask for assistance from our sales consultant.

･This product is not designed for military, aerospace, medical or other life-critical applications. If you choose to use this product

for these applications, please ask us for prior consultation or we cannot take responsibility for problems that may occur.
