Operation of the SCDQ554XX
The SCDQ554XX display consists of a CMOS IC containing con-
trol logic and drivers for four 5 x 5 characters. These components
are assemb le d in a compa ct pla sti c package.
Individual LED dot addressablity allows the user great freedom in
creating special characters or mini-icons. The User Definable
Character Set examples illustrate 200 different character and sym-
bol possibili ties. E ach e xample has th e he xadecima l code requi red
to display characters in a horizontal or vertical format. See Figures
above, Suggested Display Mounting, for the display positioning.
Generally, the contacts should be on the right side of the display
for the vertical format and on the top of the display for the horizon-
tal format.
Character Address, Row, & Column Data Map
1. Viewed from the LED side of the display with the display in a
horizontal position.
2. The row address and column data are typical for all character posi-
tions. The LED is on when the data bit = 1 and off when the data
bit = 0 .
Suggested Display Mounting
90° SIP Connector / Header Packages
The serial data inter f ace pro vides a h ighly effi cient in terconne ction
between the display and the moth er board. The SCDQ554XX
requires onl y th ree in put lines as co mpar ed to 15 for an equ iv al ent
four character parallel input part.
The on-board CMOS IC is the electronic heart of the display. The
IC accepts decoded serial data, which is stored in the internal
RAM. Asynchronously the RAM is read by the character multi -
plexer at a strobe rate that results in a flicker free display. shows
the three functional areas of the IC . These include: the in pu t se rial
data register and control logic, a 100 bits two port RAM, and an
internal multiplexer/display driver.

SCDQ Block Diagram
The following explains how to format the serial data t o be loaded into the display. The user supplies a st ring of bit mapped decoded char-
acters. The contents of this string is shown in Figure „Loading Serial Character Data A“ (page 8). Figure „Loading Serial Character
Data B“ (page 8) shows that each char acte r consists o f six 8 bit w o rd s . The first word enco de s the d ispl ay characte r lo cation and the suc-
ceeding five b ytes are row data. The row data represents the status (On, Off) of individual column LEDs. Figure „Loading Serial Character
Data C“ (page 8) shows that each 8 bit word is formatted to include a three bit Operational Code (OPCODE) defined by bits D7–D5 and
five bits (D4–D0) representing Column Data, Character Address, or Control Word Data.
Figure „Loading Serial Character Data D“ (page 8) shows the sequence f or load ing th e b ytes of da ta. Bringing the LO A D line lo w enab l es
the serial register to accep t data. The shift acti on occurs on the lo w to high tr ansition o f the serial data cloc k (SDCLK). The least s ignif icant
bit (D0) is loaded first. After eight clock pulses the LOAD line is brought high. With this transition the OPCODE is decoded. The decoded
OPCODE directs D4–D0 to be latched in the Character Address register, stored in the RAM as Column data, or latched in the Control
Word register. The control IC requires a minimum 600 ns delay between successive byte loads.

The Character Address bits, D4–D0 stored in the Character
Address Register and the Column Data Instruction’s Row Address
bits, D7–D5, direct the Column Data bits, D4–D 0 to specific RAM
location. See the Instr uction Set Table for ad dress and data format.
Figure „Writing Character ’D’ Example“ (page 9) shows the Row
Address for the example character “D” See Figure „Character
Address, Row, & Column Data Map“ (page 7) for the dot
positioning (Display contacts are at the top of the display).
Column data is written and read asynchronously from the 200 bit
RAM. Once loaded the internal oscillator and character multiplexer
reads the data from the RAM. These characters are row strobed
with column data as shown in Figure „Row Strobe Example“
(page 10). The ch aracter s trobe ra te is dete rmined by the intern al
IC’s÷320 counter.

Row Strobe Example
The user can activate four Control functions. These include: LED
Brightness Level, Lamp Test, IC Power Down, or Display Clear.
OPCODEs and five bit words are used to initiate these functions.
The OPCODEs and Control Words for the Character Address and
Loading Column Data are shown in Instruction Set Table.
The user can select seven specific LED brightness levels. These
brightness levels (in percentages of full brightness of the display)
include: 100% (F0HEX), 53% (F1HEX), 40% (F2HEX), 27%
(F3HEX), 20 % (F4HEX), 13% ( F5HEX), and 6.6% (F6HEX). The
brightness levels are controlled by changing the duty factor of the
row strobe pulse.
The SCDQ554X offers a unique Display Power Down feature
which reduces ICC to less than 50 µA. When FFHEX is loaded the
display is set to 0% brightness and the intern al multiplex clock is
stopped. When in the Power Down mode data may still be written
into the RAM. The display is reactivated by loading a new right-
ness Level Control Word into the display.
The Lamp Test is enabled by loading F8HEX into the serial shift
register. This Control Word sets all of the LEDs to a 53% bright-
ness level. Operation of the Lamp Test has no affect on the RAM
and is cleared by loading a Brightness Control Word.
The Software Clear (C0HEX) clears the Address Register and the
RAM. The dis play is blanked and the Character Addr ess Register
will be set to Character 0. The internal counter and the Control
Word Register are unaffected. The Software Clear will remain
active until the next data input cycle is initiated.
Electrical & Mechanical Considerations
Interconnect Considerations
Optimum product performance can be had when the following
electrical and mechanical recommendations are adopted. The
SCDQ554XX’s IC is constructed in a high speed CMOS process,
consequently high speed noise on the SERIAL DATA, SERIAL
DATA CLOCK, and LOAD lines may cause incorrect data to be
written into the serial shift register. Adhere to transmission line ter-
mination procedures when using fast line drivers and long cables
(>10 cm).
Good digital grounds (pin 1) and power supply deco upling (pin 2)
will insure that ICC (<350 mA peak) switching currents do not gen-
erate localized gro und bounce. Therefore it is recommended that
each dis play package use a 0.1 µF an d 20 µF capacitor between
VCC and ground.

ESD Protection
The input protection structure of the SCDQ554XX provides signifi-
cant protection ag ai nst E SD dam a ge. It is capab le of wi th s tan ding
discharges greater than 2.0 kV. Take all the standard precautions,
normal for CMOS components. These include properly grounding
personnel, tools, tables, and transport carriers that come in con-
tact with unshi elded parts. If these condi tions are not, or cannot be
met, keep the leads of the device shor ted together or the parts in
anti-static packaging.
Soldering Considerations
The SCDQ554XX can be hand soldered wi th SN 63 sol d er using a
grounded iron set to 260°C.
Wave soldering is also possible following these conditions: Pre-
heat that does n ot e xceed 93°C on t he solder si de of the PC board
or a package surface temperature of 85°C. Water soluble organic
acid flux (except carboxylic acid) or resin-based RMA flux without
alcohol can be used.
Wave temperature of 245°C ± 5°C with a dwell between 1.5 s to
3.0 s. Exposure to the wave should not exceed temperatures
above 260°C for five seconds at 1.59 mm (0.063") below the seat-
ing plane. The packages should not be imm er se d in the wave.
The SCDQ554XR connects to an external connector receptacle
which may be soldered before inserting the SCDQ554XR Display.
In this way, only the connector is subject to the user’s soldering
process. The Molex 52418-0510 receptacle called out in the prod-
uct drawing can be used in solder reflow processes. See Molex for
specifications.
Po st Solder Cl eaning Procedures
The least offensive cleaning solution is hot D.I. water (60°C) for
less than 15 minutes. Addition of mild saponifiers is acceptable.
Do not use commercial dishwasher detergents.
For faster cleaning, solvents may be used. Exercise care in choos-
ing solvents as some may chemically attack the nylon package.
For further information refer to Appnotes 18 and 19 at
www.osram-os.com or in the curren t Short Form Catalogue. See
Appnote 19, Table 2, “Displays–Group 2”.
Optical Considerations
The 3.12 mm (0.123") high character of the SCDQ554XX gives
readability up to five f ee t. Pr oper filte r se lection enha nces reada bil -
ity over this distance.
Using filters emphasizes the contrast ratio between a lit LED and
the character background. This will increase the discriminati on of
different characters. The only limitation is cost. Take into consider-
ation the ambient lighting environment for the best cost/benefit
ratio for filters .
Incandescent (with almost no green) or fluorescent (with almost no
red) lights do not have the flat spectral response of sunlight. Plas-
tic band-pass filters are an inexpensive and effective way to
strengthen contr ast ratios . The SCDQ5542 X is a super-red displa y
and should be matched with long wavelength pass filter in the
570 nm to 590 nm range. The SCDQ5541X/3X/4X should be
matched with a yellow-green band-pass filter that peaks at
565 nm. For displays of multiple colors, neutral density grey filters
offer the best compromise.
Additional contrast enhancement is gained by shading the dis-
plays. Plastic band-pass filters with built-in louvers offer the next
step up in contrast improvement. Plastic filters can be improved
further with anti-reflective coatings to reduce glare. The trade-off is
fuzzy characters. Mounting the filters close to the display reduces
this effect. Take care not to overheat the plastic filter by allowing f or
proper air flow.
Optimal filter enhancements are gained by using circular polarized,
anti-reflective, band-pass filters. The circular polarizing further
enhances contrast by reducing the light that travels through the fil-
ter and reflects back off the display to less than 1%.
Several filter manufacturers supply quality filter materials. Some of
them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homa-
lite, Wilmington, DE; 3M Company, Visual Products Division, St.
Paul, MN; Polaroid Corporation, Polarizer Division, Cambridge,
MA; Marks Polarized Corporation, Deer Park, NY, Hoya Optics,
Inc., Fremont, CA.
One last note on mounting filters: recessing displays and bezel
assemblies is an inexpensive way to provide a shading effect in
overhead lighting situations. Several Bezel manufacturers are:
R.M.F. Products, Batavia, IL; Nobex Components, Griffith Plastic
Corp., Burlingame, CA; Photo Chemical Prod ucts of Califor nia,
Santa Monica, CA; I.E.E.-Atlas, Van Nuys, CA.

Microprocessor Interface
The microprocessor in ter face is thro ug h the seria l port, SPI port or one out of eight data bits on the eight bit parallel port and also control
lines SDCLK and LOAD.
Power Up Sequence
Upon power up display will come on at random. Thus the display should be reset at power-up. The reset will set the Address Register to
Digit 0, User RAM is set to 0 (display blank) the Control Word is set to 0 (100% brightness with Lamp Test off) and the internal counters
are reset.
