GGEENNEERRAALL DDEESSCCRRIIPPTTIIOONN The ST7565S is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel or serial display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor. Because the chips in the ST7565S contain 65x132 bits of display data RAM and there is a 1-to-1 correspondence between the LCD panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The ST7565S chips contain 65 common output circuits and 132 segment output circuits, so that a single chip can drive a 65x132 dot display (capable of displaying 8 columnsx4 rows of a 16x16 dot kanji font). Moreover, the capacity of the display can be extended through the use of master/slave structures between chips. The chips are able to minimize power consumption because no external operating clock is necessary for the display data RAM read/write operation. Furthermore, because each chip is equipped internally with a low-power LCD driver power supply, resistors for LCD driver power voltage adjustment and a display clock CR oscillator circuit, the ST7565S can be used to create the lowest power display system with the fewest components for high-performance portable devices.

Ver 0.3c 24/72 2002/07/22 The Serial Interface When the serial interface has been selected (P/S = “L”) then when the chip is in active state (/CS1 = “L” and CS2 = “H”) the serial data input (SI) and the serial clock input (SCL) can be received. The serial data is read from the serial data input pin in the rising edge of the serial clocks D7, D6 through D0, in this order. This data is converted to 8 bits parallel data in the rising edge of the eighth se rial clock for the processing. The A0 input is used to determine whether or the serial data input is display data or command data; when A0 = “H”, the data is display data, and when A0 = “L” then the data is command data. The A0 input is read and used for detection every 8th rising edge of the serial clock after the chip becomes active. Figure 1 is a serial interface signal chart. 1 2 3 4 5 6 7 8 9 1 01 11 21 31 4 D7 D6 D5 D4 D3 D2 D1 D0 D7 D6 D5 D4 D3 D2 CS1 CS2 SI SCL Figure 1 * When the chip is not active, the shift registers and the counter are reset to their initial states. * Reading is not possible while in serial interface mode. * Caution is required on the SCL signal when it comes to line-end reflections and external noise. We recommend that operation be rechecked on the actual equipment. The Chip Select The ST7565S have two chip select terminals: /CS1 and CS2. The MPU interface or the serial interface is enabled only when /CS1 = “L” and CS2 = “H”. When the chip select is inactive, D0 to D7 enter a high impedance state, and the A0, /RD, and /WR inputs are inactive. When the serial interface is selected, the shift register and the counter are reset. The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the ST7565S. Wait time may not be considered. And, in the ST7565S, each time data is sent from the MPU, a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus. Internal data bus. For example, when the MPU writes data to the display data RAM, once the data is stored in the bus holder, then it is written to the display data RAM before the next data write cycle. Moreover, when the MPU reads the display data RAM, the first data read cycle (dummy) stores the read data in the bus holder, and then the data is read from the bus holder to the system bus at the next data read cycle. There is a certain restriction in the read sequence of the display data RAM. Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup. This data is generated in data read of the second time. Thus, a dummy read is required whenever the address setup or write cycle operation is conducted. This relationship is shown in Figure 2.
Ver 0.3c 25/72 2002/07/22 The Busy Flag When the busy flag is “1” it indicates that the ST7565S is running internal processes, and at this time no command aside from a status read will be received. The busy flag is outputted to D7 pin with the read instruction. If the cycle time (tCYC) is maintained, it is not necessary to check for this flag before each command. This makes vast improvements in MPU processing capabilities possible.

Ver 0.3c 26/72 2002/07/22 Display Data RAM The display data RAM stores the dot data for the LCD. It has a 65 (8 page x 8 bit +1) x 132 bit structure. As is shown in Figure 3, the D7 to D0 display data from the MPU corresponds to the LCD display common direction; there are few constraints at the time of display data transfer when multiple ST7565S are used, thus and display structures can be created easily and with a high degree of freedom. Moreover, reading from and writing to the display RAM from the MPU side is performed through the I/O buffer, which is an independent operation from signal reading for the liquid crystal driver. Consequently, even if the display data RAM is accessed asynchronously during liquid crystal display, it will not cause adverse effects on the display (such as flickering). Display data RAM COM0 COM1 COM2 COM3 COM4 Liquid crystal display Figure 3 The Page Address Circuit Page address of the display data RAM is specified through the Page Address Set Command. The page address must be specified again when changing pages to perform access. Page address 8 (D3, D2, D1, D0 = 1, 0, 0, 0) is a special RAM for icons, and only display data D0 is used. (see Figure 4) The Column Addresses The display data RAM column address is specified by the Column Address Set command. The specified column address is incremented (+1) with each display data read/write command. This allows the MPU display data to be accessed continuously. Moreover, the incrementing of column addresses stops with 83H. Because the column address is independent of the page address, when moving, for example, from page 0 column 83H to page 1 column 00H, it is necessary to respective both the page address and the column address. Furthermore, as is shown in Table 4, the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output. Because of this, the constraints on the IC layout when the LCD module is assembled can be minimized. As is shown in Figure 4, Table 4 SEG Output ADC SEG0 SEG 131 (D0) “0” (D0) “1” 0 (H) → Column Address → 83 (H) 83 (H) ← Column Address ← 0 (H) The Line Address Circuit The line address circuit, as shown in Table 4, specifies the line address relating to the COM output when the contents of the display data RAM are displayed. Using the display start line address set command, what is normally the top line of the display can be specified (this is the COM0 output when the common output mode is normal, and the COM63 output for ST7565S , the detail is shown page.11 The display area is a 65 line area for the ST7565S. If the line addresses are changed dynamically using the display start line address set command, screen scrolling, page swapping, etc. can be performed.

Ver 0.3c 28/72 2002/07/22 The Display Data Latch Circuit The display data latch circuit is a latch that temporarily stores the display data that is output to the liquid crystal driver circuit from the display data RAM. Because the display normal/reverse status, display ON/OFF status, and display all points ON/OFF commands control only the data within the latch, they do not change the data within the display data RAM itself. The Oscillator Circuit This is a CR-type oscillator that produces the display clock. The oscillator circuit is only enabled when M/S= “H” and CLS = “H”. When CLS = “L” the oscillation stops, and the external clock is input through the CL terminal. Display Timing Generator Circuit The display timing generator circuit generates the timing signal to the line address circ uit and the display data latch circuit using the display clock. The display data is latched into the display data latch circuit synchronized with the display clock, and is output to the data driver output terminal. Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU. Consequently, even if the display data RAM is accessed asynchronously during liquid crystal display, there is absolutely no adverse effect (such as flickering) on the display. Moreover, the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock. It generates a drive wave form using a 2 frame alternating current drive method, as is shown in Figure 5, for the liquid crystal drive circuit.

Ver 0.3c 31/72 2002/07/22 The Power Supply Circuits The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the LCD drivers. They are Booster circuits, voltage regulator circuits, and voltage follower circuits. They are only enabled in master operation. The power supply circuits can turn the Booster circuits, the voltage regulator circuits, and the voltage follower circuits ON or OFF independently through the use of the Power Control Set command. Consequently, it is possible to make an external power supply and the internal power supply function somewhat in parallel. Table 7 shows the Power Control Set Command 3-bit data control function, and Table 8 shows reference combinations.

Ver 0.3c 33/72 2002/07/22 The Voltage Regulator Circuit The step-up voltage generated at VOUT outputs the LCD driver voltage V5 through the voltage regulator circuit. Because the ST7565S chips have an internal high-accuracy fixed voltage power supply with a 64-level electronic volume function and internal resistors for the V 5 voltage regulator, systems can be constructed without having to include high-accuracy voltage regulator circuit components.

Test mode clear On the other hand, when the reset command is used, the above default settings from 11 to 19 are only executed. When the power is turned on, the IC internal state becomes unstable, and it is necessary to initialize it using the /RES terminal. After the initialization, each input terminal should be controlled normally. Moreover, when the control signal from the MPU is in the high impedance, an over current may flow to the IC. After applying a current, it is necessary to take proper measures to prevent the input terminal from getting into the high impedance state. If the internal liquid crystal power supply circuit is not used on ST7565S,it is necessary that /RES is “H” when the external liquid crystal power supply is turned on. This IC has the function to discharge V 5 when /RES is “L,” and the external power supply short-circuits to V DD when /RES is “L.” While /RES is “L,” the oscillator and the display timing generator stop, and the CL, FR, FRS and /DOF terminals are fixed to “H.” The terminals D0 to D7 are not affected. The V DD level is output from the SEG and COM output terminals. This means that an internal resistor is connected between V DD and V5. When the internal liquid crystal power supply circuit is not used on other models of ST7565S series, it is necessary that /RES is “L” when the external liquid crystal power supply is turned on. While /RES is “L,” the oscillator works but the display timing generator stops, and the CL, FR, FRS and /DOF terminals are fixed to “H.” The terminals D0 to D7 are not affected.
Ver 0.3c 42/72 2002/07/22 CCOOMMMMAANNDDSS The ST7565S identify the data bus signals by a combination of A0, /RD (E), /WR(R/W) si gnals. Command interpretation and execution does not depend on the external clock, but rather is performed through internal timing only, and thus the processing is fast enough that normally a busy check is not required. In the 8080 MPU interface, commands are launched by inputting a low pulse to the RD terminal for reading, and inputting a low pulse to the /WR terminal for writing. In the 6800 Series MPU interface, the interface is placed in a read mode when an “H” signal is input to the R/W terminal and placed in a write mode when a “L” signal is input to the R/W terminal and then the command is launched by inputting a high pulse to the E terminal. Consequently, the 6800 Series MPU interface is different than the 80x86 Series MPU interface in that in the explanation of commands and the display commands the status read and display data read /RD (E) becomes “1(H)”. In the explanations below the commands are explained using the 8080 Series MPU interface as the example. When the serial interface is selected, the data is input in sequence starting with D7. <Explanation of Commands> Display ON/OFF This command turns the display ON and OFF.

Specifying the page address and column address enables to access a desired bit of the display data RAM. Changing the page address does not accompany a change in the status display.

The column address is split into two sections (the higher 4 bits and the lower 4 bits) when it is set (fundamentally, set continuously). Each time the display data RAM is accessed, the column address automatically increments (+1), making it possible for the MPU to continuously read from/write to the display data. The column address increment is topped at 83H. This does not change the page address continuously. See the function explanation in “The Column Address Circuit,” for details.

RESET This indicates that the chip is in the process of initialization either because of a /RES signal or because of a reset command. 0: Operating state 1: Reset in progress Display Data Write This command writes 8-bit data to the specified display data RAM address.

Ver 0.3c 44/72 2002/07/22 Display Data Read This command reads 8-bit data from the specified display dat a RAM address. Since the column address is automatically incremented by “1” after the read, the CPU can continuously read multiple-word data. One dummy read is required immediately after the column address has been set. See the function explanation in “Display Data RAM” for the explanation of accessing the internal registers. When the serial interface is used, reading of the display data becomes unavailable. E R/W A0 /RD /WR D7 D6 D5 D4 D3 D2 D1 D0 1 0 1 Read data ADC Select (Segment Driver Direction Select) This command can reverse the correspondence between the display RAM data column address and the segment driver output. Thus, sequence of the segment driver output pins may be reversed by the command. See the column address circuit (page 1–20) for the detail. Increment of the column address (by “1”) accompanying the reading or writing the display data is done according to the column address indicated in Figure 4.

This command is a two byte command used as a pair with the electronic volume mode set command and the electronic volume register set command, and both commands must be issued one after the other. The Electronic Volume Mode Set When this command is input, the electronic volume register set command becomes enabled. Once the electronic volume mode has been set, no other command except for the electronic volume register command can be used.

The static indicator display is controlled by this command only, and is independent of other display control commands. This is used when one of the static indicator liquid crystal driv e electrodes is connected to the FR terminal, and the other is connected to the FRS terminal. A different pattern is recommended for the static indicator electrodes than for the dynamic drive electrodes. If the pattern is too close, it can result in deterioration of the liquid crystal and of the electrodes. The static indicator ON command is a double byte command paire d with the static indicator register set command, and thus one must execute one after the other.

Ver 0.3c 50/72 2002/07/22 Sleep Mode This stops all operations in the LCD display system, and as long as there are no accesses from the MPU, the consumption current is reduced to a value near the static current. The internal modes during sleep mode are as follows: 1. The oscillator circuit and the LCD power supply circuit are halted. 2. All liquid crystal drive circuits are halted, and the segment in common drive outputs output a V DD level. Standby Mode The duty LCD display system operations are halted and only the st atic drive system for the indicator continues to operate, providing the minimum required consumption current for the static drive. The internal modes are in the following states during standby mode. 1 The LCD power supply circuits are halted. The oscillator circuit continues to operate. 2 The duty drive system liquid crystal drive circuits are halted and the segment and common driver outputs output a V DD level. The static drive system does not operate. When a reset command is performed while in standby mode, the system enters sleep mode. * When an external power supply is used, it is recommended that the functions of the external power supply circuit be stopped when the power saver mode is started. For example, when the va rious levels of liquid crystal drive voltage are provided by external resistive voltage dividers, it is recommended that a circuit be added in order to cut the electrical current flowing through the resistive voltage divider circuit when the power saver mode is in effect. The ST7565S series chips have a liquid crystal display blanking control terminal /DOF. This termi nal enters an “L” state when the power saver mode is launched. Using the output of /DOF, it is possible to stop the function of an external power supply circuit. * When the master is turned on, the oscillator circuit is operable immediately after the powering on. The Booster Ratio (Double Byte Command) This command makes it possible to select step-up ratio. It is used when the power control set have turn on the internal booster circuit. This command is a two byte command used as a pair with the booster ratio select mode set command and the booster ratio register set command, and both commands must be issued one after the other. Booster Ratio Select Mode Set When this command is input, the Booster ratio register set command becomes enabled. Once the booster ratio select mode has been set, no other command except for the booster ratio register command can be used.
