14 SPLC78D 6COM/4SEG CONTROLLER/DRIVER. GENERAL DESCRIPTION The SPLC78D, a dot-matrix LCD controller and driver from SUNPLUS, is a unique design for displaying alpha-numeric, Japanese-Kana characters and symbols. The SPLC78D provides two types of interfaces to MPU: 4-bit and 8-bit interfaces. The transferring speed of 8-bit is twice faster than 4-bit. A single SPLC78D is able to display up to two 8-character lines. By cascading with SPLC or SPLC63, the display capability can be extended. The CMOS technology ensures the power saves in the most efficient way and the performance keeps in the highest rank. 2.

23 SPLC78D 5.8. Display Data RAM (DD RAM) The 8-bit DD RAM is normally used for storing display data. Those DD RAM not used for display data can be used as general data RAM. Its address is configured in the Address Counter. The relationships between Display Data RAM Address and LCD s position are depicted as follows. -line display, 8 display characters ( Example ) -line display, 8 display characters E 4F Display position Display data RAM address Display position Display data RAM address When the display shift operation is performed, the display data RAM's address moves as : ( i ) Left shift ( ii ) Right shift 8 4F Timing Generation Circuit The timing generating circuit is able to generate timing signals to the internal circuits. In order to prevent the internal timing interface, the MPU access timing and the RAM access timing are generated independently. 5.. Character Generator ROM (CG ROM) Using 8-bit character code, the character generator ROM generates 5 x 8 dots or 5 x dots character patterns. It also can generate 92 s 5 x 8 dots character patterns and 64 s 5 x dots character patterns. 5.. LCD Driver Circuit Total of 6 commons and 4 segments signal drivers are valid in the LCD driver circuit. When a program specifies the character fonts and line numbers, the corresponding common signals output drive-waveforms and the others still output unselected waveforms Character Generator RAM (CG RAM) Users can easily change the character patterns in the character generator RAM through program. It can be written to 5 x 8 dots, 8-character patterns or 5 x dots for 4-character patterns. 2 AUG. 6, 23 Preliminary Version:.

Note2: These areas are not used for display, but can be used for the general data RAM. Note3: When all of the bit4-7 of the character code are, CG RAM character patterns are selected. Note4: " ": Selected, " " : No selected, " X " : Do not care ( or ). Note5: For example (), set character code (b2 = b = b =, b3 = or, b7-b4 = ) to display T. That means character code () 6,and (8) 6 can display T character. Note6: The bits -2 of the character code RAM is the character pattern line position. The 8th line is the cursor position and display is formed by logical OR with the cursor. 4 AUG. 6, 23 Preliminary Version:.

Note2: These areas are not used for display, but can be used for the general data RAM. Note3: When all of the bit4-7 of the character code are, CG RAM character patterns are selected. Note4: " : Selected, " : No selected, " X : Do not care ( or ). Note5: For example (), set character code (b2 = b =, b3 = b = or, b7-b4 = ) to display U. That means all of the character codes () 6, () 6, (8) 6,and (9) 6 can display U character. Note6: The bits -3 of the character code RAM is the character pattern line position. The th line is the cursor position and display is formed by logical OR with the cursor. 5 AUG. 6, 23 Preliminary Version:.

27 SPLC78D 5.3. Cursor/Blink Control Circuit This circuit generates the cursor or blink in the cursor / blink control circuit. The cursor or the blink appears in the digit at the Display Data RAM Address defined in the Address Counter. When the Address Counter is (7) 6, the cursor position is shown as belows: b6 b5 b4 b3 b2 b b AC In a -line display digit the cursor position Display position Display data RAM address ( Hexadecimal ) In a 2-line display digit st line 2nd line Display position Display data RAM address ( Hexadecimal ) the cursor position 5.4. Interfacing to MPU There are two types of data operations: 4-bit and 8-bit operations. Using 4-bit MPU, the interfacing 4-bit data is transferred by 4-busline (DB4 to DB7). Thus, DB to DB3 bus lines are not used. Using 4-bit MPU to interface 8-bit data requires two times transferring. First, the higher 4-bit data is transferred by 4-busline (for 8-bit operation, DB7 to DB4). Secondly, the lower 4-bit data is transferred by 4-busline (for 8-bit operation, DB3 to DB).

30 SPLC78D 5.6. REGISTER --- IR (Instruction Register) and DR (Data Register) SPLC78D contains two 8-bit registers: Instruction Register (IR) and Data Register (DR). Using combinations of the RS pin and the R/W pin selects the IR and DR, see below: 5.9. I/O Port Configuration Input port: E VDD PMOS RS R/W Operation IR write (Display clear, etc.) Read busy flag (DB7) and Address Counter (DB - DB6) DR write (DR to Display data RAM or Character generator RAM) DR read (Display data RAM or Character generator RAM to DR) The IR can be written by MPU, but it cannot be read by MPU Busy Flag (BF) Input port: R/W, RS VDD PMOS NMOS VDD PMOS NMOS When RS = and R/W =, the busy flag is output to DB7. As the busy flag =, SPLC78D is in busy state and does not accept any instruction until the busy flag = Address Counter (AC) The Address Counter assigns addresses to Display Data RAM and Character Generator RAM. When an instruction for address is written in IR, the address information is sent from IR to AC. After writing to/reading from Display Data RAM or Character Generator RAM, AC is automatically incremented by one (or decremented by one). The contents of AC are output to DB - DB6 when RS = and R/W = Output port: CL, CL2, M, D VDD PMOS NMOS Input / Output port: DB7 - DB VDD VDD VDD Enable PMOS PMOS NMOS Data 9 AUG. 6, 23 Preliminary Version:.

44 USING LCD MODULES LIQUID CRYSTAL DISPLAY MODULES LCD s are composed of glass, liquid crystal fluid, and a polarizer. Please pay attention to the following items when handling:. Keep the temperature within a specified range for use and storage. Polarization degradation, bubble generation or polarizer peel off may occur with high temperatures and high humidity. 2. Do not touch, push or rub the exposed polarizer with anything harder than an HB lead pencil (glass, tweezers, etc). 3. N hexane is recommended for cleaning the adhesives used to attach the front/rear polarizer. Reflectors made of organic substances will be damaged by chemicals such as acetone, toluene, ethanol and isopropyl alcohol. 4. If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, wipe it gently with absorbent cotton or another soft material like a chamois soaked in Isopropyl alcohol or Ethyl alcohol. Scrub gently to avoid damaging the display surface. 5. Wipe off saliva or water immediately! Contact with water over a long period of time may cause deformation or color fading. 6. Avoid contact with oil or any greasy substances. 7. If there is condensation on the surface and contact with the terminals while cold, it will damage, stain or dirty the polarizer. After the product is tested at a low temperature, they must be warmed up in a container before being exposed to room temperature environments. 8. Do not put or attach anything on the display area in order to avoid leaving marks. 9. Do not touch the display with bare hands. This will stain the display area and degrade the insulation between terminals. (Some cosmetics are detrimental to the polarizer).. Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a high humidity environment.. As glass is fragile, care should be taken to avoid chipping, while handling the edges especially. PRECAUTIONS FOR HANDLING LCD MODULES Since the LCD module has been assembled and adjusted with a high degree of precision, avoid applying excessive shock or force to the module or making any alterations or modifications to it.. Do not alter, modify or change the shape of the tab on the metal frame. 2. Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. 3. Do not damage or modify the pattern wiring on the printed circuit board. 4. Absolutely do not modify the zebra rubber strip (conductive rubber) or heat the seal connector! 5. Except for soldering the interface, do not make any alterations or modifications with a soldering iron. 6. Do not drop, bend or twist the LCD module. In particular, don t forcibly pull or bend the I/O cable or backlight cable.

45 7. In order to avoid cracking the FPC, pay attention to the area where the FPC is bent, the edge of the overlay, the area of the surface of Ni Au plating, the area of soldering land, and the area of the through hole. ELECTRO STATIC DISCHARGE CONTROL Since this module uses a CMOS LSI, give the same careful attention to the electrostatic discharge as you would for an ordinary CMOS IC.. Make sure you are grounded when handling LCD modules. To minimize the performance degradation of the LCD modules resulting from destruction caused by static electricity, exercise care to avoid holding the following sections when handling the modules: exposed area of the printed circuit board, terminal electrode sections. 2. Before removing the LCD module from its packing case or incorporating it into a set, be sure the module and your body have the same electric potential. 3. When soldering the terminal of the LCD module, make sure the AC power source for the soldering iron does not leak. 4. When using an electric screwdriver to attach the LCD module, the screwdriver should be of ground potentiality, to minimize any transmission of electromagnetic waves producing sparks coming from the commutator of the motor. 5. As far as possible, make the electric potential of your work clothes and that of the work bench the ground potential. 6. To reduce the generation of static electricity, be careful that the air in the working environment is not too dry. (A relative humidity of 5 6% is recommended). PRECAUTIONS FOR OPERATION. Viewing angle varies with the change of liquid crystal driving voltage (VO). Adjust VO to show the best contrast. 2. Driving the LCD in the voltage above the limit shortens its life. 3. If the LCD modules have been operating for a long time showing the same display patterns, the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear. A normal operating status can be regained by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability. 4. Response time is greatly delayed at temperatures below the operating temperature range, however this does not mean the LCD will be out of order. It will recover when it returns to the specified temperature range. 5. If the display area is pushed hard during operation, the display may become abnormal, however it will return to normal if it is turned off and then turned back on. 6. Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit, therefore it must be used under the relative condition of 4 C, 5% RH. 7. When turning the power on, input each signal after the positive/negative voltage becomes stable.

46 STORAGE WHEN STORING LCD S, THE FOLLOWING PRECAUTIONS ARE NECESSARY:. Store them in a sealed polyethylene bag. If properly sealed, there is no need for desiccant. 2. Store them in a dark place; do not expose them to sunlight or fluorescent light. Keep the temperature between C and 35 C. 3. The polarizer surface should not come in contact with any other objects. (We advise you to store them in the container in which they were shipped). 4. Environmental conditions: A). Do not leave them for more than 6 hours at 7 C B). They should not be left for more than 48 hours at 2 C SAFETY. It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off with solvents such as acetone and ethanol, which should later be burned. 2. If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash off thoroughly with soap and water.
