These components are assembled in a compact plastic package. The serial data interface provides a highly efficient interconnection between the display and the mother board. The SCDQ554XX requires only three input lines as compared to 15 for an equivalent 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 multiplexer at a strobe rate that results in a flicker free display. shows the three functional areas of the IC. These include: the input serial data register and control logic, a 100 bits two port RAM, and an internal multiplexer/display driver. 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 symbol possibilities. Each example has the hexadecimal code required 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 horizontal format. 2010-04-13 7 SCDQ5541P/Q/R, SCDQ5542P/Q/R, SCDQ5543P/Q/R, SCDQ5544P/Q/R SCDQ Block Diagram Counter Chain & Timing Row Decoder & Driver Oscillator Lamp Test 4-5x5 Characters 5 20 Column Logic & Driver Power Down Control Word Register 5 20 3 Software Clear & 20 x 5 bit Dual Port Ram Column Output 3 Write Character/Row Address Decode Character Adddress Register Display Multiplexer OPCODE Decoder Serial Data Register D7 D6 D5 D4 D3 D2 D1 D0 OPCODE DATA Brightness SDCLK SDATA LOAD IDBD5061 The following explains how to format the serial data to be loaded into the display. The user supplies a string of bit mapped decoded characters. 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 character consists of six 8 bit words. The first word encodes the display character location and the succeeding five bytes 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 for loading the bytes of data. Bringing the LOAD line low enables the serial register to accept data. The shift action occurs on the low to high transition of the serial data clock (SDCLK). The least significant 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.

See the Instruction Set Table for address 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 character strobe rate is determined by the internal IC's/320 counter.

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 Lamp Test is enabled by loading F8HEX into the serial shift register. This Control Word sets all of the LEDs to a 53% brightness level. Operation of the Lamp Test has no affect on the RAM and is cleared by loading a Brightness Control Word.

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 termination procedures when using fast line drivers and long cables (>10 cm). Good digital grounds (pin 1) and power supply decoupling (pin 2) will insure that ICC (<350 mA peak) switching currents do not generate localized ground bounce. Therefore it is recommended that each display package use a 0.1 F and 20 F capacitor between VCC and ground. Power Down Control Word D4 D3 D2 Control Word D4 D3 D2 The Software Clear (C0HEX) clears the Address Register and the RAM. The display is blanked and the Character Address 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. The SCDQ554X offers a unique Display Power Down feature which reduces ICC to less than 50 A. When FFHEX is loaded the display is set to 0% brightness and the internal 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 rightness Level Control Word into the display.

Take care not to overheat the plastic filter by allowing for 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 filter and reflects back off the display to less than 1%. The input protection structure of the SCDQ554XX provides significant protection against ESD damage. It is capable of withstanding 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 contact with unshielded parts. If these conditions are not, or cannot be met, keep the leads of the device shorted together or the parts in anti-static packaging. Several filter manufacturers supply quality filter materials. Some of them are: Panelgraphic Corporation, W. Caldwell, NJ; SGL Homalite, 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. Soldering Considerations The SCDQ554XX can be hand soldered with SN63 solder using a grounded iron set to 260C. 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 Products of California, Santa Monica, CA; I.E.E.-Atlas, Van Nuys, CA. Wave soldering is also possible following these conditions: Preheat that does not exceed 93C on the solder side of the PC board or a package surface temperature of 85C. Water soluble organic acid flux (except carboxylic acid) or resin-based RMA flux without alcohol can be used. Wave temperature of 245C 5C with a dwell between 1.5 s to 3.0 s. Exposure to the wave should not exceed temperatures above 260C for five seconds at 1.59 mm (0.063") below the seating plane. The packages should not be immersed 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 product drawing can be used in solder reflow processes. See Molex for specifications. Post Solder Cleaning Procedures The least offensive cleaning solution is hot D.I. water (60C) 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 choosing 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 current 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 feet. Proper filter selection enhances readability over this distance. Using filters emphasizes the contrast ratio between a lit LED and the character background. This will increase the discrimination of different characters. The only limitation is cost. Take into consideration 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. Plastic band-pass filters are an inexpensive and effective way to strengthen contrast ratios. The SCDQ5542X is a super-red display 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 displays. 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 2010-04-13 11 SCDQ5541P/Q/R, SCDQ5542P/Q/R, SCDQ5543P/Q/R, SCDQ5544P/Q/R SCDQ554XX Interface to Siemens/Intel 8031 Microprocessor (using serial port in mode 0) VCC VCC RxD TxD P3.3 XTAL 4 2 SDATA 3 SDCLK 1 LOAD SCDQ554XX 8031 VCC + RST 0.01 F 20 F 5 IDCD5022 SCDQ554XX Interface to Siemens/Intel 8031 Microprocessor (using one bit of parallel port as serial input) VCC VCC P0.0 P3.6 P3.0 XTAL 4 2 SDATA 3 SDCLK 1 LOAD SCDQ554XX 8031 VCC + RST 0.01 F 20 F 5 IDCD5023 Microprocessor Interface The microprocessor interface is through the serial port, SPI port or one out of eight data bits on the eight bit parallel port and also control lines SDCLK and LOAD.
