1.0 GENERAL DESCRIPTION
1.1 Introduction
This specification describes the interface requirements and features of a two-line Vacuum Fluorescent
Display, 20 characters wide. The characters are formed using a 5x7 dot matrix.
1.2 Application
This unit may be used as a console display which provides alphanumeric information that is easily readable in
high ambient light. It is ideal for point-of-sale terminals, office computers, and a wide range of business and
industrial equipment.
1.3 Special Features
"Minimum depth" Hardware reset
Low cost Software dimming
Hardware interrupt Extended/European character set
10 User defined characters Superset of 03601-951
1.4 Description
This Vacuum Fluorescent Display is a self-contained multiplexed unit which provides a simple interface to a
microprocessor system.
This unit consists of a vacuum fluorescent display tube and a minimal amount of electronic hardware. All
display characters and standard control codes are in a 8-bit format. All inputs are TTL compatible. Primary
complexity is contained within the microprocessor software, which controls all display functions.
Timing is not critical for data communication except which is shown in Section 5.5. Data is entered in parallel
at rates determined by execution times.
A single +5VDC power supply (approximately 370mA typical for brightest setting) is required for operation.
Total power is about 1.8 watts.
A wide spectrum of color filters is available to fit all applications. The characters are bright, but soft, providing
comfortable short or long-term viewing.
An ASCII-coded English font employs a 96 character set with an extended European character set and 10
user defined characters.
Figure 3 depicts the character sets as displayed by the 03601-95B-40 module.

3.0 THEORY OF OPERATION (Dot Matrix Displays)
The Vacuum Fluorescent Display array consists of three basic electrodes which are enclosed in an evacuated
glass chamber. The first electrode is the filament, which spans the entire length of the display, and is made
from a small diameter oxide coated tungsten wire. This element is common to all characters and supplies the
electron emission needed for operation. Individual grid electrodes are provided, one for each character, to
control current passing to the anodes. Each grid is a fine mesh metal screen which provides digit-select
electrical control with no visual interference. When the grid is positive with respect to the filament, electrons
are allowed to pass on to the third electrode, the anode dots, causing the fluorescent phosphor coating on
each positively charged dot to glow. Selectively energizing these fluorescent dots causes the desired
character to be displayed.

Busy status is available on J1-1. This signal may be used as a hardware interrupt for the host processor
when the display is busy. High busy signal indicates that the display is busy.

4.8 Dedicated Hardware Lines
4.8.1 RESET
Hardware RESET is available on J1-14. Setting RESET low for greater than 50µS will clear the display and
set the cursor to the upper left character (power-up condition). Sinking current must be able to discharge a
1µF capacitor connected internally.
4.8. INTERRUPT (BUSY)
A busy signal is available on J1-1 and may be used to interrupt the host signaling a READY condition.
4.9 Self-Test
The display will go into self-test mode, if E2 is connected to the ground. In the self-test mode, the display will
display every printable character from 20 (HEX) to FF (HEX) until E2 is disconnected from ground.

5.0 ELECTRICAL CHARACTERISTICS
5.1 Power ON / OFF Sequence
There are no deleterious effects associated with power ON and OFF of this display; however, rapid ON/OFF
sequencing is not recommended. The power/data connector should not be connected/disconnected while
power is applied.
CAUTION: Do not apply data or strobe signals unless logic power is also applied; otherwise, the input
circuits may be damaged.
Because of the power-up cycle within the microprocessor, rise time of the power supply should be less than
100mS. The display module is not ready to accept data for 500mS.
5.2 Interface Signals
All logic signals abide by the following convention: logic "1" is a high, logic "0" is a low.
Input Levels:
Logic 1 > 2.4VDC @ 1µA.
Logic 0 < 0.5VDC @ 1.6mA.
Output Levels:
Logic 1 > 3.5VDC @ 150µA.
Logic 0 < 0.5VDC @ 4mA.
All parallel interface lines are internally pulled up using 10K resistors connected to the +5V supply.
5.3 Absolute Maximum Ratings
Primary voltage: +5.5VDC
Logic range: -0.5VDC thru +5.5VDC
5.4 Normal Operating Ratings
