Page 9 of 40009 ## **Function Description** ## ● **System Interface** This chip has all four kinds of interface type with MPU: 4-bit bus, 8-bit bus, serial and fast I2C interface. 4-bit bus or 8-bit bus is selected by DL bit in the instruction register. During read or write operation, two 8-bit registers are used. One is data register (DR), the other is instruction register(IR). The data register(DR) is used as temporary data storage place for being written into or read from DDRAM/CGRAM/ICON RAM, target RAM is selected by RAM address setting instruction. Each internal operation, reading from or writing into RAM, is done automatically. So to speak, after MPU reads DR data, the data in the next DDRAM/CGRAM/ICON RAM address is transferred into DR automatically. Also after MPU writes data to DR, the data in DR is transferred into DDRAM/CGRAM/ICON RAM automatically. The Instruction register(IR) is used only to store instruction code transferred from MPU. MPU cannot use it to read instruction data. To select register, use RS input pin in 4-bit/8-bit bus mode. ## **I2C interface** ## **It just only could write Data or Instruction to ST7036 by the IIC Interface. It could not read Data or Instruction from ST7036 (except Acknowledge signal).** SCL: serial clock input SDA_IN: serial data input SDA_OUT: acknowledge response output ## **Slaver address could set from “0111100” to “0111111”.** The I2C interface send RAM data and executes the commands sent via the I2C Interface. It could send data in to the RAM. The I2C Interface is two-line communication between different ICs or modules. The two lines are a Serial Data line (SDA) and a Serial Clock line (SCL). Both lines must be connected to a positive supply via a pull-up resistor. Data transfer may be initiated only when the bus is not busy. Page 10 of 40010 ## **BIT TRANSFER** One data bit is transferred during each clock pulse. The data on the SDA line must remain stable during the HIGH period of the clock pulse because changes in the data line at this time will be interpreted as a control signal. Bit transfer is illustrated in Fig.1. ## **START AND STOP CONDITIONS** Both data and clock lines remain HIGH when the bus is not busy. A HIGH-to-LOW transition of the data line, while the clock is HIGH is defined as the START condition (S). A LOW-to-HIGH transition of the data line while the clock is HIGH is defined as the STOP condition (P). The START and STOP conditions are illustrated in Fig.2. ## **SYSTEM CONFIGURATION** The system configuration is illustrated in Fig.3. · Transmitter: the device, which sends the data to the bus · Master: the device, which initiates a transfer, generates clock signals and terminates a transfer · Slave: the device addressed by a master - Multi-Master: more than one master can attempt to control the bus at the same time without corrupting the message · Arbitration: procedure to ensure that, if more than one master simultaneously tries to control the bus, only one is allowed to do so and the message is not corrupted · Synchronization: procedure to synchronize the clock signals of two or more devices. ## **ACKNOWLEDGE** ## **Acknowledge signal (ACK) is not BF signal in parallel interface.** Each byte of eight bits is followed by an acknowledge bit. The acknowledge bit is a HIGH signal put on the bus by the transmitter during which time the master generates an extra acknowledge related clock pulse. A slave receiver which is addressed must generate an acknowledge after the reception of each byte. A master receiver must also generate an acknowledge after the reception of each byte that has been clocked out of the slave transmitter. The device that acknowledges must pull-down the SDA line during the acknowledge clock pulse, so that the SDA line is stable LOW during the HIGH period of the acknowledge related clock pulse (set-up and hold times must be taken into consideration). A master receiver must signal an end-of-data to the transmitter by not generating an acknowledge on the last byte that has been clocked out of the slave. In this event the transmitter must leave the data line HIGH to enable the master to generate a STOP condition. Acknowledgement on the I2C Interface is illustrated in Fig.4. Page 11 of 40011 Page 12 of 40012 ## **I2C Interface protocol** The ST7036 supports command, data write addressed slaves on the bus. Before any data is transmitted on the I2C Interface, the device, which should respond, is addressed first. Four 7-bit slave addresses (01111 **00** to 01111 **11** ) are reserved for the ST7036. The R/W is assigned to 0 for Write only. The I2C Interface protocol is illustrated in Fig.5. The sequence is initiated with a START condition (S) from the I2C Interface master, which is followed by the slave address. All slaves with the corresponding address acknowledge in parallel, all the others will ignore the I2C Interface transfer. After acknowledgement, one or more command words follow which define the status of the addressed slaves. A command word consists of a control byte, which defines Co and RS, plus a data byte. The last control byte is tagged with a cleared most significant bit (i.e. the continuation bit Co). After a control byte with a cleared Co bit, only data bytes will follow. The state of the RS bit defines whether the data byte is interpreted as a command or as RAM data. All addressed slaves on the bus also acknowledge the control and data bytes. After the last control byte, depending on the RS bit setting; either a series of display data bytes or command data bytes may follow. If the RS bit is set to logic 1, these display bytes are stored in the display RAM at the address specified by the data pointer. The data pointer is automatically updated and the data is directed to the intended ST7036i device. If the RS bit of the last control byte is set to logic 0, these command bytes will be decoded and the setting of the device will be changed according to the received commands. Only the addressed slave makes the acknowledgement after each byte. At the end of the transmission the I2C INTERFACE-bus master issues a STOP condition (P). Page 13 of 40013 During write operation, two 8-bit registers are used. One is data register (DR), the other is instruction register(IR). The data register(DR) is used as temporary data storage place for being written into DDRAM/CGRAM/ICON RAM, target RAM is selected by RAM address setting instruction. Each internal operation, writing into RAM, is done automatically. So to speak, after MPU writes data to DR, the data in DR is transferred into DDRAM/CGRAM/ICON RAM automatically. The Instruction register(IR) is used only to store instruction code transferred from MPU. MPU cannot use it to read instruction data. To select register, use RS bit input in IIC interface. ## ● **Busy Flag (BF)** When BF = "High”, it indicates that the internal operation is being processed. So during this time the next instruction cannot be accepted. BF can be read, when RS = Low and R/W = High (Read Instruction Operation), through DB7 port. Before executing the next instruction, be sure that BF is not High. ## ● **Address Counter (AC)** Address Counter(AC) stores DDRAM/CGRAM/ICON RAM address, transferred from IR. After writing into (reading from) DDRAM/CGRAM/ICON RAM, AC is automatically increased (decreased) by 1. When RS = "Low" and R/W = "High", AC can be read through DB0 ~ DB6 ports. ## ● **Display Data RAM (DDRAM)** Display data RAM (DDRAM) stores display data represented in 8-bit character codes. Its extended capacity is 80x 8 bits, or 80 characters. The area in display data RAM (DDRAM) that is not used for display can be used as general data RAM. See Figure 6 for the relationships between DDRAM addresses and positions on the liquid crystal display. The DDRAM address (ADD ) is set in the address counter (AC) as hexadecimal. ## ● **1-line display (N3=0,N = 0) (Figure 7)** When there are fewer than 80 display characters, the display begins at the head position. For example, if using only the ST7036, 20 characters are displayed. See Figure 7. When the display shift operation is performed, the DDRAM address shifts. See Figure 8. Page 14 of 40014 ## ● **2-line display (N3=0,N = 1) (Figure 9)** Case 1: When the number of display characters is less than 40 x _2 lines, the two lines are displayed from the head. Note that the first line end address and the second line start address are not consecutive. For example, when just the ST7036 is used, 20 characters x _2 lines are displayed. See Figure 9. When display shift operation is performed, the DDRAM address shifts. See Figure 10. Page 15 of 40015 ## _ **3-line display (N3=1,N =1) (Figure 11)** Case 1: When the number of display characters is less than 16 x _3 lines, the tree lines are displayed from the head. For example, when just the ST7036 is used, 16 characters x _3 lines are displayed. See Figure 11. When display shift operation is performed, the DDRAM address shifts. See Figure 12. Page 16 of 40016 ## ● **Character Generator ROM (CGROM)** The character generator ROM generates 5 x 8 dot character patterns from 8-bit character codes. It can generate 240/250/248/256 5 x 8 dot character patterns(select by OPR1/2 ITO pin). User-defined character patterns are also available by mask-programmed ROM. ## ● **Character Generator RAM (CGRAM)** In the character generator RAM, the user can rewrite character patterns by program. For 5 x 8 dots, eight character patterns can be written. Write into DDRAM the character codes at the addresses shown as the left column of Table 5 to show the character patterns stored in CGRAM. See Table 5 for the relationship between CGRAM addresses and data and display patterns. Areas that are not used for display can be used as general data RAM. Page 17 of 40017 ## ● **ICON RAM** ## **In the ICON RAM, the user can rewrite icon pattern by program.** ## **There are totally 80 dots for icon can be written.** ## **See Table 6 for the relationship between ICON RAM address and data and the display patterns.** ## ● **Timing Generation Circuit** The timing generation circuit generates timing signals for the operation of internal circuits such as DDRAM, CGROM and CGRAM. RAM read timing for display and internal operation timing by MPU access are generated separately to avoid interfering with each other. Therefore, when writing data to DDRAM, for example, there will be no undesirable interference, such as flickering, in areas other than the display area. ## ● **LCD Driver Circuit(N3=0)** LCD Driver circuit has 17 common and 100 segment signals for LCD driving. Data from CGRAM/CGROM/ICON is transferred to 100 bit segment latch serially, and then it is stored to 100 bit shift latch. When each common is selected by 17 bit common register, segment data also output through segment driver from 100 bit segment latch. In case of 1-line display mode, COM1 ~ COM8(with COMI) have 1/9 duty, and in 2-line mode, COM1 ~ COM16(with COMI) have 1/17 duty ratio. ## ● **LCD Driver Circuit(N3=1)** LCD Driver circuit has 25 common and 80 segment signals for LCD driving. Data from CGRAM/CGROM/ICON is transferred to 80 bit segment latch serially, and then it is stored to 80 bit shift latch. When each common is selected by 25 bit common register, segment data also output through segment driver from 80 bit segment latch. In case of 3-line display mode, COM1 ~ COM24(with COMI) have 1/25 duty. ## ● **Cursor/Blink Control Circuit** It can generate 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 set in the address counter. Page 18 of 40018 Page 19 of 40019 Notes: 1. Character code bits 0 to 2 correspond to CGRAM address bits 3 to 5 (3 bits: 8 types). 2. CGRAM address bits 0 to 2 designate the character pattern line position. The 8th line is the cursor position and its display is formed by a logical OR with the cursor. Maintain the 8th line data, corresponding to the cursor display position, at 0 as the cursor display. If the 8th line data is 1, 1 bits will light up the 8th line regardless of the cursor presence. 3. Character pattern row positions correspond to CGRAM data bits 0 to 4 (bit 4 being at the left). 4. As shown Table 5, CGRAM character patterns are selected when character code bits 4 to 7 are all 0. However, since character code bit 3 has no effect, the T display example above can be selected by either character code 00H or 08H. 5. “1” for CGRAM data corresponds to display selection and “0” to non-selection,“-“ Indicates no effect. 6. Different OPR1/2 ITO option can select different CGRAM size. Page 20 of 40020 Page 21 of 40021 ## ■ **Instructions** There are four categories of instructions that: - **Designate ST7036 functions, such as display format, data length, etc.** - **Set internal RAM addresses** - **Perform data transfer with internal RAM** ## ● **Others** - **instruction table at “Normal mode”** (when “EXT” option pin connect to VDD, the instruction set follow below table) ## Note: Be sure the ST7036 is not in the busy state (BF = 0) before sending an instruction from the MPU to the ST7036. If an instruction is sent without checking the busy flag, the time between the first instruction and next instruction will take much longer than the instruction time itself. Refer to Instruction Table for the list of each instruction execution time.
