GENERAL DESCRIPTION The ST7565 is a single-chip dot matrix LCD drivers 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 ST7565 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 ST7565chips 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 PART NO. ST7565-0A ST7565-0B Ver 1.0a 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 ST7565 can be used to create the lowest power display system with the fewest components for high-performance portable devices.

the reference power supply for the step-up voltage circuit for the liquid crystal drive. This is the externally-input VREG power supply for the LCD power supply voltage regulator. These are only enabled for the models with the VREG external input option. 4 2 Power This is a multi-level power supply for the liquid crystal drive. The voltage Supply applied is determined by the liquid crystal cell, and is changed through the use of a resistive voltage divided or through changing the impedance using an op. amp. Voltage levels are determined based on VDD, and must maintain the relative magnitudes shown below.

Through selecting the P/ S terminal polarity to the “H” o r “L ” it is p o s s ib l e t o s e le c t e ith e r p a r a lle l data input or serial data input as shown in Table 1.

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 serial 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.

We recommend that operation be rechecked on the actual equipment. The Chip Select The ST7565 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 ST7565. Wait time may not be considered. And, in the ST7565, 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, Ver 1.0a 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. 13/56 2002/06/24 ST7565 The Busy Flag When the busy flag is “1” it indicates that the ST7565 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.

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 ST7565 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).

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 incrimination 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 respectively 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 (D0) “0” (D0) “1” SEG0 SEG 131 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 Ver 1.0a for ST7565 , the detail is shown page.11 The display area is a 65 line area for the ST7565. If the line addresses are changed dynamically using the display start line address set command, screen scrolling, page swapping, etc. can be performed. 15/56 2002/06/24 ST7565 0 1 ADC Column addres s 83 D0 D0 LCD Out 82 00 S131 81 01 S130 80 02 S129 7F 03 S128 7E 04 S127 7D COM Output COM0 COM1 COM2 COM3 COM4 COM5 COM6 COM7 COM8 COM9 COM10 COM11 COM12 COM13 COM14 COM15 COM16 COM17 COM18 COM19 COM20 COM21 COM22 COM23 COM24 COM25 COM26 COM27 COM28 COM29 COM30 COM31 COM32 COM33 COM34 COM35 COM36 COM37 COM38 COM39 COM40 COM41 COM42 COM43 COM44 COM45 COM46 COM47 COM48 COM49 COM50 COM51 COM52 COM53 COM54 COM55 COM56 COM57 COM58 COM59 COM60 COM61 COM62 COM63 COMS Page 8 05 0 06 0 S126 0 S125 1 Page 7 7B 1 7C 1 07 1 08 0 Page 6 S124 0 S123 1 08 1 07 0 Page 5 7B 1 S8 0 06 1 7C 0 Page 4 S7 0 05 0 7D 1 S6 0 Page 3 04 1 7E 1 S5 0 03 0 Page 2 7F 0 S4 1 02 0 80 0 Page 1 S3 1 01 0 81 0 S2 0 When the common output is normal 00H 01H 02H 03H 04H 05H 06H 07H 08H 09H 0AH 0BH 0CH 0DH 0EH 0FH 10H 11H 12H 13H 14H 15H 16H 17H 18H 19H 1AH 1BH 1CH 1DH 1EH 1FH 20H 21H 22H 23H 24H 25H 26H 27H 28H 29H 2AH 2BH 2CH 2DH 2EH 2FH 30H 31H 32H 33H 34H 35H 36H 37H 38H 39H 3AH 3BH 3CH 3DH 3EH 3FH Page 0 00 0 82 0 83 0 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 D1 D2 D3 D4 D5 D6 D7 D0 S0 0 Line Address Data S1 Page Address D3 D2 D1 D0 Regardless of the display start line address, 1/65duty => 65th line, 1/49duty =>49th line. 1/33duty =>33th line, 1/55duty =>55th line, 1/53duty =>53th line. Figure 4 Ver 1.0a 16/56 2002/06/24 ST7565 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 circuit 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.

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.

The Step-up Voltage Circuits Using the step-up voltage circuits equipped within the ST7565 chips it is possible to product a Quad step-up, a Triple step-up, and a Double step-up of the VDD – VSS2 voltage levels. Quad step-up: Connect capacitor C1 between CAP1+ and CAP1–, between CAP2+ and CAP2–, between CAP1+ and CAP3–, and between VSS2 and VOUT, to produce a voltage level in the negative direction at the VOUT terminal that is 4 times the voltage level between VDD and VSS2. Triple step-up: Connect capacitor C1 between CAP1+ and CAP1–, between CAP2+ and CAP2– and Ver 1.0a between VSS2 and VOUT, and short between CAP3– and VOUT to produce avoltage level in the negative direction at the VOUT terminal that is 3 times the voltage difference between VDD and VSS2. Double step-up: Connect capacitor C1 between CAP1+ and CAP1–, and between VSS2 and VOUT, leave CAP2+ open, and short between CAP2–, CAP3– and VOUT to produce a voltage in the negative direction at the VOUT terminal that Is twice the voltage between VDD and VSS2. The step-up voltage relationships are shown in Figure 7. 20/56 2002/06/24 ST7565 VSS2 VSS2 VSS2 C1 C1 C1 VOUT VOUT VOUT CAP3- CAP3- CAP3- C1 ST7565 C1 CAP1+ ST7565 CAP1+ ST7565 C1 CAP1+ C1 CAP1- CAP1- CAP1- CAP2- CAP2- CAP2- C1 C1 CAP2+ 4x step-up voltage circuit CAP2+ 3x step-up voltage circuit VDD=0V VDD=0V VSS2=-3V VSS2=-3V VOUT=3xVSS2=-9V OPEN CAP2+ 2x step-up voltage circuit VDD=0V VSS2=-5V VOUT=3xVSS2=-10V VOUT=4xVSS2=-12V 4x step-up voltage relationships 3x step-up voltage relationships 2x step-up voltage relationships Figure 7 * The VSS2 voltage range must be set so that the VOUT terminal voltage does not exceed the absolute maximum rated value. The Voltage Regulator Circuit The step-up voltage generated at VOUT outputs the LCD driver voltage V5 through the voltage regulator circuit. Because the ST7565 chips have an internal high-accuracy fixed voltage power supply with a 64-level electronic volume function and internal resistors for the V5 voltage regulator, systems can be constructed without having to include high-accuracy voltage regulator circuit components. Moreover, in the ST7565, Two types of thermal gradients have been prepared as VREG options: (1) approximately -0.15%/°C (2) external input (supplied to the VRS terminal) (A) When the V5 Voltage Regulator Internal Resistors Are Used Through the use of the V5 voltage regulator internal resistors and the electronic volume function the liquid crystal power supply voltage V5 can be controlled by commands alone (without adding any external resistors), making it possible to Ver 1.0a adjust the liquid crystal display brightness. The V5 voltage can be calculated using equation A-1 over the range where | V5 | < | VOUT |. 21/56 2002/06/24 ST7565 V ( Rb Ra ) α Rb =(1 + 1V 162 ) Ra ) ( α [∵ V = ( 1 - 162 ) V ] V5 = 1 + EV REG EV REG VDD VEV(constant voltage supply+electronic volume) Internal Ra V5 Internal Rb Figure 8 VREG is the IC-internal fixed voltage supply, and its voltage at Ta = 25°C is as shown in Table 9.

Rb/Ra is the V5 voltage regulator internal resistor ratio, and can be set to 8 different levels through the V5 voltage regulator internal resistor ratio set command. The (1 + Rb/Ra) ratio assumes the values shown in Table 11 depending on the 3-bit data settings in the V5 voltage regulator internal resistor ratio register.

Setup example: When selecting Ta = 25°C and V5 = –7V for an ST7565-0A on which Temperature gradient = –0.15%/°C. Using Figure 9 and the equation A-1, the following setup is enabled. At this time, the variable range and the notch width of the V5 voltage is, as shown Table 13, as dependent on the electronic volume.

When this is done, the use of the electronic volume function makes it possible to adjust the brightness of the liquid crystal display by controlling the liquid crystal power supply voltage V 5 through commands. In the range where | V5 | < | VOUT |, the V5 voltage can be calculated using equation B-1 based on the external resistances Ra’ and Rb’.

When the central value of the electron volume register is (D5, D4, D3, D2, D1, D0) = (1, 0, 0, 0, 0, 0), then α = 31 and VREG = –2.1V so, according to equation B-1, α 1( Rb' Ra' ) ( 162 ) Rb' 31 -7V = ( 1 + 1Ra' ) ( 162 ) V5 = 1 + Ra'+ Rb'= 1.4MΩ Consequently, by equations B-2 and B-3, Rb' = 3.12 Ra' Ra' = 340kΩ Rb' = 1060kΩ VREG (-2.1) At this time, the V5 voltage variable range and notch width, based on the electron volume function, is as given in Table 14.

In this case, the use of the electronic volume function makes it possible to control the liquid crystal power supply voltage V5 by commands to adjust the liquid crystal display brightness. In the range where | V5 | < | VOUT | the V5 voltage can be calculated by equation C-1 below based on the R1 and R2 (var ia ble res ist or) and R 3 se ttings , whe re R 2 can be subjected to fine adjustments (Δ R2).

When the central value for the electronic volume register is set at (D5, D4, D3, D2, D1, D0) = (1, 0, 0, 0, 0, 0), then α = 31 and VREG = –2.1 V so, according to equation C-1, when ΔR2 = 0 Ω, in order to make V5 = –9 V, ( -5V= 1 + R3 R1+R2 31 ) ( 1 - 162 ) ( -9V= 1 + R3+R2 R1 31 ) ( 1 - 162 ) (-2.1) When the current flowing VDD and V5 is set to 5 uA, R1+ R2 + R2 = 1.4MΩ With this, according to equation C-2, C-3 and C-4, R1 = 264kΩ R2 = 211kΩ R3 = 925kΩ (-2.1) When ΔR2 = R2, in order to make V = –5 V, The V5 voltage variable range and notch width based on the electron volume function is as shown in Table 15.

Moreover, it is necessary to provide a voltage from VOUT when the Booster circuit is OFF. * The VR terminal is enabled only when the V5 voltage regulator internal resistors are not used (i.e. the IRS terminal = “L”). When the V5 voltage regulator internal resistors are used (i.e. when the IRS terminal = “H”), then the V R terminal is left open. * Because the input impedance of the VR terminal is high, it is necessary to take into consideration short leads, shield cables, etc. to handle noise. The LCD Voltage Generator Circuit when the voltage follower changes the impedance, it provides V1, V2, V3 and V4 to the liquid crystal drive circuit. The V5 voltage is produced by a resistive voltage divider within the IC, and can be produced at the V1, V2, V3, and V4 voltage levels required for liquid crystal driving. Moreover, High Power Mode The power supply circuit equipped in the ST7565 chips has very low power consumption (normal mode: HPM = “H”). However, for LCDs or panels with large loads, this low-power power supply may cause display quality to degrade. When this occurs, setting the HPM terminal to “L” (high power mode) can improve the quality of the display. We recommend that the display be checked on actual equipment to determine whether or not to use this mode. Moreover, if the improvement to the display is inadequate even after high power mode has been set, then it is necessary to add a liquid crystal drive power supply externally. The Internal Power Supply Shutdown Command Sequence The sequence shown in Figure 13 is recommended for shutting down the internal power supply, first placing the Sequence Step1 Step2 End power supply in power saver mode and then turning the power supply OFF.

Note that all C2 capacitors must have the same capacitance value. • Next turn all the power supplies ON and determine C1.

Test mode clear Ver 1.0a 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 ST7565,it is necessary that /RES is “H” when the external liquid crystal power supply is turned on. This IC has the function to discharge V5 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 VDD level is output from the SEG and COM output terminals. This means that an internal resistor is connected between VDD and V5. When the internal liquid crystal power supply circuit is not used on other models of ST7565 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. 31/56 2002/06/24 ST7565 COMMANDS The ST7565 identify the data bus signals by a combination of A0, /RD (E), /WR(R/W) signals. 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.

See the section on the power saver for details. Display Start Line Set This command is used to specify the display start line address of the display data RAM shown in Figure 4. For further details see the explanation of this function in “The Line Address Circuit”.

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. A0 0 E /RD 1 R/W /WR 0 D7 D6 D5 D4 D3 D2 D1 D0 Page address 1 0 1 1 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1 0 1 0 0 1 2 ↓ 7 8 ↓ 0 1 Ver 1.0a 32/56 2002/06/24 ST7565 Column Address Set This command specifies the column address of the display data RAM shown in Figure 4. 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.

This shows the relationship between the column address and the segment driver. 0: Reverse (column address 131-n ↔ SEG n) 1: Normal (column address n ↔ SEG n) (The ADC command switches the polarity.) ON/OFF: indicates the display ON/OFF state. 0: Display ON 1: Display OFF (This display ON/OFF command switches the polarity.) 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. Since the column address is automatically incremented by “1” after the write, the MPU can write the display data.

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. A0 E R/W /RD /WR 1 0 D7 D6 D5 D4 D3 D2 D1 D0 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.

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.

YES Figure 26 Static Indicator (Double Byte Command) This command controls the static drive system indicator display. 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 drive 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 paired with the static indicator register set command, and thus one must execute one after the other. (The static indicator OFF command is a single byte command.) Static Indicator ON/OFF When the static indicator ON command is entered, the static indicator register set command is enabled. Once the static indicator ON command has been entered, no other command aside from the static indicator register set command can be used.

YES Figure 27 Power Save (Compound Command) When the display all points ON is performed while the display is in the OFF mode, the power saver mode is entered, thus greatly reducing power consumption. The power saver mode has two different modes: the sleep mode and the standby mode. When the static indicator is OFF, it is the sleep mode that is entered. When the static indicator is ON, it is the standby mode that is entered. In the sleep mode and in the standby mode, the display data is saved as is the operating mode that was in effect before the power saver mode was initiated, and the MPU is still able to access the display data RAM. Refer to figure 28 for power save off sequence. Static indicator ON Static indicator OFF Display OFF Display OFF Display all point ON Display all point ON Standby mode Sleep mode Power save OFF ( Display all point OFF ) Power save OFF Display all point OFF Static indicator ON (2 bytes) Standby mode cancel Sleep mode cancel Figure 28 Ver 1.0a 39/56 2002/06/24 ST7565 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 VDD level. Standby Mode The duty LCD display system operations are halted and only the static 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 VDD 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 various 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 ST7565 series chips have a liquid crystal display blanking control terminal /DOF. This terminal 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.

Moreover, it is recommended that the operating modes be refreshed periodically to prevent the effects of unanticipated noise.

When electric charge is remaining in the smoothing capacitor connecting between the LCD driving voltage output pins (V1 ~ V5) and the VDD pin, the picture on the display may become totally dark instantaneously when the power is turned on. To avoid occurrence of such a failure, we recommend the following flow when turning on the power. 1.

For tH, refer to the <Reference Data> of this event. When t H is too long, insert a resistor between V 5 and VDD to reduce it. Notes: Reference items *14: The logic circuit of this IC’s power supply VDD - VSS controls the driver of the LCD power supply VDD - V5. So, if the power supply VDD - VSS is cut off when the LCD power supply VDD - V5 has still any residual voltage, the driver (COM. SEG) may output any uncontrolled voltage. When turning off the power, observe the following basic procedures: • After turning off the internal power supply, make sure that the potential V5 ~ V1 has become below the threshold voltage of the LCD panel, and then turn off this IC’s power supply (VDD - VSS). 6.

Ver 1.0a 54/56 2002/06/24 ST7565 THE MPU INTERFACE (REFERENCE EXAMPLES) The ST7565 Series can be connected to either 80X86 Series MPUs or to 68000 Series MPUs. Moreover, using the serial interface it is possible to operate the ST7565 series chips with fewer signal lines. The display area can be enlarged by using multiple ST7565 Series chips. When this is done, the chip select signal can be used to select the individual ICs to access.
