2? scd5580/5581/5582/5583/5584 the scd558x requires only 4 lines as compared to 15 for an equivalent 8 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 char- acter multiplexer at a strobe rate that results in a ?cker free display. figure 8 shows the three functional areas of the ic. these include: the input serial data register and control logic, a 200 bits two port ram, and an internal multiplexer/ display driver. operation of the scd558x the scd558x display consists of a cmos ic containing con- trol logic and drivers for eight 5x5 characters. these compo- nents are assembled in a compact (38 mm x 10 mm) plastic package. individual led dot addressablity allows the user great free- dom in creating special characters or mini-icons. the user de?able character set examples illustrate 200 different character and symbol possibilities. the use of a serial data interface provides a highly ef?ient interconnection between the display and the mother board. figure 8. scd558x block diagram character address register d7 d6 d5 opcode d4 d3 d2 d1 d0 data opcode decode serial data ?5 ?3 load serial data clock display multiplexer column output column logic & driver oscillator counter chain & timing logic mux clk i/o mux clock sel software clear reset ?20 brightness & lamp test power down 5 write character/ row address decode 5 4 row decoder & driver 10 8 - 5x5 characters 012 3 4567 ram 200 bits write 40 x 5 read 10 x 20 control word address register
2? scd5580/5581/5582/5583/5584 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 9a. figure 9b shows that each character consist of six 8 bit words. the ?st word encodes the display character location and the succeeding ?e bytes are row data. the row data represents the status (on, off) of individ- ual column leds. figure 9c shows that each that each 8 bit word is formatted to include a three bit operational code (opcode) de?ed by bits d7?5 and ?e bits (d4?0) rep- resenting column data, character address, or control word data. figure 9d 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 transi- tion of the serial data clock (sdclk). the least signi?ant bit (d0) is loaded ?st. 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. as indicated in figure 9a, a total of 528 bits of data are required to load all eight characters into the display. row address register bits, d7?5 (table 3), direct the col- umn data bits, d4?0 (table 3) to speci? ram location. table 1 shows the row address for the example character ?.?column data is written and read asynchronously from the 200 bit ram. once loaded the internal oscillator and charac- ter multiplexer reads the data from the ram. these charac- ters are row strobed with column data as shown in figures 8 and 9. the character strobe rate is determined by the internal or user supplied external mux clock and the ics ? 320 counter. table 1. character ? opcode column data hex d7 d6 d5 d4 d3 d2 d1 d0 row 0 000111101e row 1 0011000131 row 2 0101000151 row 3 0111000171 row 4 100111109e figure 9a?. loading serial character data character 0 character 1 character 2 character 3 character 4 character 5 character 6 character 7 528 clock cycles, 105.6 ? example: serial clock = 5 mhz, clock period = 200 ns time between loads load serial clock data clock period t 0 d0 d1 d2 d3 d4 d5 d6 d7 11 clock cycles, 2.2 ? time between loads opcode character address opcode column data d0 c4 d1 c3 d2 c2 d3 c1 d4 c0 character 0 address row 0 column data 66 clock cycles, 13.2 ? row 1 column data row 2 column data row 3 column data row 4 column data d0 0 d1 0 d2 0 d3 0 d4 0 d5 1 d6 0 d7 0 d5 d6 d7 a. b. c. d. 11 clock cycles, 2.2 ? 600 ns(min.) time between loads 600 ns(min.)
2? scd5580/5581/5582/5583/5584 the user can activate four control functions. these include: led brightness level, lamp test, ic power down, or display clear. opcodes and ?e bit words are used to initiate these functions. the opcodes and control words for the charac- ter address and loading column data are shown in tables 2 and 3. table 2. load character address table 3. load column data figure 10. row and column location opcode character address operation load d7 d6 d5 d4 d3 d2 d1 d0 10100000a0 character 0 10100001a1 character 1 10100010a2 character 2 10100011a3 character 3 10100100a4 character 4 10100101a5 character 5 10100110a6 character 6 10100111a7 character 7 opcode column data operation load d7 d6 d5 d4 d3 d2 d1 d0 000c0c1c2c3c4 row 0 001c0c1c2c3c4 row 1 010c0c1c2c3c4 row 2 011c0c1c2c3c4 row 3 100c0c1c2c3c4 row 4 off led on led row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns previously ?n?led the user can select seven speci? led brightness levels, table 4. these brightness levels (in percentages of full bright- ness of the display) include: 100% (f0 hex ), 53% (f1 hex ), 40% (f2 hex ), 27% (f3 hex ), 20% (f4 hex ), 13% (f5 hex ), and 6.6% (f6 hex ). the brightness levels are controlled by chang- ing the duty factor of the row strobe pulse. table 4. display brightness the scd558x offers a unique display power down feature which reduces i cc to less than 50 m a. when ff hex is loaded, as shown in table 5, 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 dis- play is reactivated by loading a new brightness level control word into the display. table 5. power down the lamp test is enabled by loading f8 hex , table 6, 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. opcode control word hex operation level d7 d6 d5 d4 d3 d2 d1 d0 11110000f0 100% 11110001f153% 11110010f240% 11110011f327% 11110100a420% 11110101f513% 11110110f6 6.6% opcode control word hex operation d7 d6 d5 d4 d3 d2 d1 d0 11111111ff 0% brightness figure 11. row strobing row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns row 0 row 1 row 2 row 3 row 4 0 1 2 3 4 columns row load load row 0 load row 1 load row 2 load row 3 load row 4

(1) note: 1.acceptable commercial solvents are: basic tf, arklone, p. genesolv, d. genesolv da, blaco-tron tf, blaco-tron ta, and freon ta. unacceptable solvents contain alcohol, methanol, methylene chloride, ethanol, tp35, tcm, tmc, tms+, te, or tes. since many commercial mixtures exist, contact a solvent vendor for chemical composition information. some major solvent manufacturers are: allied chemical corporation, specialty chemical division, morristown, nj; baron-blakeslee, chi- cago, il; dow chemical, midland, mi; e.i. dupont de nem- ours & co., wilmington, de. for further information refer to appnotes 18 and 19 in the cur- rent siemens optoelectronic data book. an alternative to soldering and cleaning the display modules is to use sockets. naturally, 28 pin dip sockets .300" wide with .100" centers work well for single displays. multiple dis- play assemblies are best handled by longer sip sockets or dip sockets when available for uniform package alignment.
