OKI Semiconductor ML9058 FEDL9058-01 Issue Date: Sep. 18, 2003 132-Channel LCD Driver with Built-in RAM for LCD Dot Matrix Displays GENERAL DESCRIPTION The ML9058 is an LSI for dot matrix graphic LCD devices carrying out bit map display. This LSI can drive a dot matrix graphic LCD display panel under the control of an 8-bit microcomputer (hereinafter described MPU). Since all the functions necessary for driving a bit map type LCD device are incorporated in a single chip, using the ML9058 makes it possible to realize a bit map type dot matrix graphic LCD display system with only a few chips. Since the bit map method in which one bit of display RAM data turns ON or OFF one dot in the display panel, it is possible to carry out displays with a high degree of freedom such as Chinese character displays, etc. With one chip, it is possible to construct a graphic display system with a maximum of 65 × 132 dots. The display can be expanded further using two chips. However, the ML9058 is not used in a multiple chip configuration when a line reversal drive is set. The ML9058 is made using a CMOS process. Because it has a built-in RAM, low power consumption is one of its features, and is therefore suitable for displays in battery-operated portable equipment. The ML9058 has 65 common signal outputs and 132 segment signal outputs and one chip can drive a display of up to 65 × 132 dots.

Table 2 Selection of interface type (parallel/serial) P/S CS1 CS2 A0 RD WR C86 D7 H: Parallel input CS1 CS2 A0 RD WR C86 L: Serial input CS1 CS2 A0 — — — D6 DB0 to DB5 D7 D6 SI SCL DB0 to DB5 — A hyphen (—) indicates that the pin can be tied to the “H” or the “L” level. • Parallel interface When the parallel interface is selected, (P/S = “H”), it is possible to connect this LSI directly to the MPU bus of either an 80-series MPU or a 68-series MPU as shown in Table 3. depending on whether the pin C86 is set to “H” or “L”. Table 3 Selection of MPU during parallel interface (80–/68–series) CS1 CS2 A0 RD WR DB0 to DB7 H: 68-Series MPU bus CS1 CS2 A0 E R/W DB0 to DB7 L: 80-Series MPU bus CS1 CS2 A0 RD WR DB0 to DB7 C86 The data bus signals are identified as shown in Table 4 below depending on the combination of the signals A0, RD (E), and WR (R/W) of Table 3. Table 4 Identification of data bus signals during parallel interface Common 68-Series 80-Series A0 R/W RD WR Display data read 1 1 0 1 Display data write 1 0 1 0 Status read 0 1 0 1 Control data write (command) 0 0 1 0 20/76 FEDL9058-01 OKI Semiconductor ML9058 Serial Interface When the serial interface is selected (P/S = “L”), the serial data input (SI) and the serial clock input (SCL) can be accepted if the chip is in the active state (CS1 = “L” and CS2 = “H”). The serial interface consists of an 8-bit shift register and a 3-bit counter. The serial data is read in from the serial data input pin in the sequence DB7, DB6, ... , DB0 at the rising edge of the serial clock input, and is converted into parallel data at the rising edge of the 8th serial clock pulse and processed further. The identification of whether the serial data is display data or command is judged based on the A0 input, and the data is treated as display data when A0 is “H” and as command when A0 is “L”. The A0 input is read in and identified at the rising edge of the (8 × n) th serial clock pulse after the chip has become active. Fig. 1 shows the signal chart of the serial interface. (When the chip is not active, the shift register and the counter are reset to their initial states. No data read out is possible in the case of the serial interface. It is necessary to take sufficient care about wiring termination reflection and external noise in the case of the SCL signal. We recommend verification of operation in an actual unit.)

When the chip select signals are in the inactive state, the DB0 to DB7 lines will be in the high impedance state and the inputs A0, RD, and WR will not be effective. When the serial interface has been selected, the shift register and the counter are reset when the chip select signals are in the inactive state. • Accessing the display data RAM and the internal registers Accessing the ML9058 from the MPU side requires merely that the cycle time (tCYC) be satisfied, and high speed data transfer without requiring any wait time is possible. Also, during the data transfer with the MPU, the ML9058 carries out a type of pipeline processing between LSIs via a bus holder associated with the internal data bus. For example, when the MPU writes data in the display data RAM, the data is temporarily stored in the bus holder, and is then written into the display data RAM before the next data read cycle. Further, when the MPU reads out data in the display data RAM, first a dummy data read cycle is carried out to temporarily store the data in the bus holder which is then placed on the system bus and is read out during the next read cycle. There is a restriction on the read sequence of the display data RAM, which is that the read instruction immediately after setting the address does not read out the data of that address, but that data is output as the data of the address specified during the second data read sequence, and hence care should be taken about this during reading. Therefore, always one dummy read is necessary immediately after setting the address or after a write cycle: (The status read cannot use dummy read cycles.) This relationship is shown in Figs 2(a) and 2(b). 21/76 FEDL9058-01 OKI Semiconductor ML9058 MPU • Data write WR DATA Dn Dn + 1 Dn + 2 Dn + 3 Internal timing Latch Dn BUS Holder Dn + 1 Dn + 2 Dn + 3 Write Signal Fig. 2(a) Write sequence of display data RAM • Data read MPU WR RD DATA N unknown Dn Dn + 1 Internal timing Address Preset Read Signal Column Address Preset N Dn unknown BUS Holder Address Set N Increment N + 1 Data Read (Dummy) N+2 Dn + 1 Data Read Dn Dn + 2 Data Read Dn + 1 Fig. 2(b) Read sequence of display data RAM Dn = Data N = Address data • Busy flag The busy flag being “1” indicates that the ML9058 is carrying out reset operations, and hence no instruction other than a status read instruction is accepted during this period. The busy flag is output at pin DB7 when a status read instruction is executed. 22/76 FEDL9058-01 OKI Semiconductor ML9058 Display Data RAM • Display data RAM This is the RAM storing the dot data for display and has an organization of 65 (8 pages × 8 bits +1) × 132 bits. It is possible to access any required bit by specifying the page address and the column address. Since the display data DB7 to DB0 from the MPU corresponds to the LCD display in the direction of the common lines as shown in Fig. 3, there are fewer restrictions during display data transfer when the ML9058 is used in a multiple chip configuration, thereby making it easily possible to realize a display with a high degree of freedom. Also, since the display data RAM read/write from the MPU side is carried out via an I/O buffer, it is done independent of the signal read operation for the LCD drive. Consequently, the display is not affected by flickering, etc., even when the display data RAM is accessed asynchronously during the LCD display operation.

Specify the page address again when accessing after changing the page. The page address 8 (DB3, DB2, DB1, DB0 → 1, 0, 0, 0) is the RAM area dedicated to the indicator, and only the display data DB0 is valid in this page. • Column address circuit The column address of the display data RAM is specified using the column address set command as shown in Fig. 4. Since the specified column address is incremented (by +1) every time a display data read/write command is issued, the MPU can access the display data continuously. Further, the incrementing of the column address is stopped at the column address of 83(H). Since the column address and the page address are independent of each other, it is necessary, for example, to specify separately the new page address and the new column address when changing from column 83(H) of page 0 to column 00(H) of page 1. Also, as is shown in Table 5, it is possible to reverse the correspondence relationship between the display data RAM column address and the segment output using the ADC command (the segment driver direction select command). This reduces the IC placement restrictions at the time of assembling LCD modules. Table 5 Correspondence relationship between the display data RAM column address and the segment output ADC SEGMENT Output SEG0 SEG131 DB0 = “0” 0(H) → Column Address → 83(H) DB0 = “1” 83(H) ← Column Address ← 0(H) 23/76 FEDL9058-01 OKI Semiconductor ML9058 • Line address circuit The line address circuit is used for specifying the line address corresponding to the common output when displaying the contents of the display data RAM as is shown in Fig. 4. Normally, the topmost line in the display is specified using the display start line address set command (COM0 output in the forward display state of the common output, and COM63 output in the reverse display state). The display area is 64 lines in the direction of increasing line address from the specified display start line address. When the indicator–dedicated common output pin (COMS) is selected, data in Line Address 40 H = page 8 and bit 0 is displayed irrespective of the display start line address. COMS selection is 65th in order. It is possible to carry out screen scrolling by dynamically changing the line address using the display start line address set command. • Display data latch circuit The display data latch circuit is a latch for temporarily storing the data from the display data RAM before being output to the LCD drive circuits. Since the commands for selecting forward/reverse display and turning the display ON/OFF control the data in this latch, the data in the display data RAM will not be changed. Oscillator Circuit This is an RC oscillator that generates the display clock. The oscillator circuit is effective only when M/S = “H” and also CLS = “H”. The oscillations will be stopped when CLS = “L”, and the display clock has to be input to the CL pin. 24/76 FEDL9058-01 OKI Semiconductor 0 1 1 0 0 1 1 1 1 0 0 0 48 Lines Page4 Page5 Page6 Page7 Page8 1 0 DB0 DB0 ADC Column Address 0 1 0 1 Page3 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 COMS The 40(H) is displayed irrespective of the display start line address.

The display data is latched in the display data latch circuit and is output to the segment drive output pins in synchronization with the display clock. This circuit generates the timing signals for the line address circuit and the display data latch circuit from the display clock. The display data is latched in the display data latch circuit and is output to the segment drive output pins in synchronization with the display clock. The read out of the display data to the LCD drive circuits is completely independent of the display data RAM access from the MPU. As a result, there is no bad influence such as flickering on the display even when the display data RAM is accessed asynchronously during the LCD display. Also, the internal common timing and LCD frame reversal (FR) signals are generated by this circuit from the display clock. The drive waveforms of the frame reversal drive method shown in Fig. 5(a) for the LCD drive circuits are generated by this circuit. The drive waveforms of the line reversal drive method shown in Fig. 5(b) are also generated by the command. 48 49 1 2 3 4 5 6 44 45 46 47 48 49 1 2 3 4 5 6 LCDCK (display clock) FR V1 V2 COM0 V5 VSS V1 V2 COM1 V5 VSS RAM DATA V1 V3 SEGn V4 VSS Fig. 5(a) Waveforms in the frame reversal drive method 26/76 FEDL9058-01 OKI Semiconductor ML9058 48 49 1 2 3 4 5 6 44 45 46 47 48 49 1 2 3 4 5 6 LCDCK (display clock) FR V1 V2 COM0 V5 VSS V1 V2 COM1 V5 VSS RAM DATA V1 V3 V4 VSS SEGn Fig. 5(b) Waveforms in the line reversal drive method When the ML9058 is used in a multiple chip configuration, it is necessary to supply the slave side display timing signals (FR, CL, and DOF) from the master side. However, when the line reversal drive is set, the ML9058 is not used in a multiple chip configuration. The statuses of the signals FR, CL, and DOF are shown in Table 6. Table 6 Display timing signals in master mode and slave mode Operating mode Master mode (M/S = “H”) Slave mode (M/S = “L”) FR CL DOF Internal oscillator circuit enabled (CLS = H) Output Output Output Internal oscillator circuit disabled (CLS = L) Output Input Output Internal oscillator circuit disabled (CLS = H) Input Input Input Internal oscillator circuit disabled (CLS = L) Input Input Input Note: During master mode, the oscillator circuit operates from the time the power is applied. The oscillator circuit can be stopped only in the sleep state. 27/76 FEDL9058-01 OKI Semiconductor ML9058 Common Output State Selection Circuit (see Table 7) Since the common output scanning directions can be set using the common output state selection command in the ML9058, it is possible to reduce the IC placement restrictions at the time of assembling LCD modules. Table 7 Common output state settings State Common Scanning direction Forward Display COM0 → COM63 Reverse Display COM63 → COM0 LCD Drive Circuit This LSI incorporates 181 sets of multiplexers for the ML9058, that generate 4-level outputs for driving the LCD. These output the LCD drive voltage in accordance with the combination of the display data, common scanning signals, and the FR signal. Fig. 6 shows examples of the segment and common output waveforms in the frame reversal drive method. Static Indicator Circuit The FR pin is connected to one side of the LCD drive electrode of the static indicator and the FRS pin is connected to the other side. The static indicator display is controlled by a command only independently of other display control commands. The electrode of the static indicator should has a wiring pattern that is distant from the dynamic drive electrode. If the wiring pattern is placed too near to the dynamic drive electrode, the LCD and electrode may be degraded. 28/76 FEDL9058-01 COM0 COM1 COM2 COM3 COM4 COM5 COM6 COM7 COM8 COM9 CO M10 CO M11 CO M12 CO M13 CO M14 CO M15 ML9058 SEG4 SEG3 SEG2 SEG1 SEG0 OKI Semiconductor FR COM0 COM1 COM2 SEG0 SEG1 SEG2 C O M 0 -S E G 0 C O M 0 -S E G 1 V DD V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 V SS V1 V2 V3 V4 V5 0V -V 5 -V 4 -V 3 -V 2 -V 1 V1 V2 V3 V4 V5 0V -V 5 -V 4 -V 3 -V 2 -V 1 Fig. 6 Output waveforms in the frame reversal drive method (FR waveform/common waveform/segment waveform/voltage difference between common and segment) 29/76 FEDL9058-01 OKI Semiconductor ML9058 Power Supply Circuit This is the low power consumption type power supply circuit for generating the voltages necessary for driving LCD devices, and consists of voltage multiplier circuits, voltage adjustment circuits, and voltage follower circuits. In the power supply circuit, it is possible to control the ON/OFF of each of the circuits of the voltage multiplier, voltage adjustment circuits, and voltage follower circuits using the power control set command. As a result, it is also possible to use parts of the functions of both the external power supply and the internal power supply. Table 8 shows the functions controlled by the 3-bit data of the power control set command and Table 9 shows a sample combination.

Since the ML9058 incorporates a high accuracy constant voltage generator, a 64-level electronic potentiometer function, and also resistors for voltage V1 adjustment, it is possible to build a high accuracy voltage adjustment circuit with very few components. In addition, the ML9058 is available with the temperature gradients of a VREG - about –0.05%/°C. (a) When the internal resistors for voltage V1 adjustment are used It is possible to control the LCD power supply voltage V1 and adjust the intensity of LCD display using commands and without needing any external resistors, if the internal voltage V1 adjustment resistors and the electronic potentiometer function are used. The voltage V1 can be obtained by the following equation A-1 in the range of V1<VOUT. V1 = (1 + (Rb/Ra)) • VEV = (1 + (Rb/Ra)) • (1 – (α/324)) • VREG (Eqn. A-1) VRS (VREG) VEV (Constant voltage supply + electronic potentiometer) + V1 – VR Internal Ra Internal Rb Fig. 9 V1 voltage adjustment circuit (equivalent circuit) 32/76 FEDL9058-01 OKI Semiconductor ML9058 VREG is a constant voltage generated inside the IC and VRS pin output voltage. Here, α is the electronic potentiometer function which allows one level among 64 levels to be selected by merely setting the data in the 6-bit electronic potentiometer register. The values of α set by the electronic potentiometer register are shown in Table 10.

The reference values of the ratio (1 + Rb/Ra) according to the 3-bit data set in the voltage V1 adjustment internal resistor ratio setting register are listed in Table 11. Table 11 Voltage V1 adjustment internal resistor ratio setting register values and the ratio (1+Rb/Ra) (Nominal) Register (1 + Rb/Ra) DB2 DB1 DB0 0 0 0 3.0 0 0 1 3.5 0 1 0 4.0 0 1 1 4.5 1 0 0 5.0 1 0 1 5.5 1 1 0 6.0 Note: Use V1 gain in the range from 3 to 6 times. Because this LSI has temperature gradient, V1 voltage rises at lower temperatures. When using V1 gain of 6 times, adjust the built-in electronic potentiometer so that V1 voltage does not exceed 18 V. When V1 is set using the built-in resistance ratio, the accuracies are shown in Table 12. Table 12 Relation between V1 Output Voltage Accuracy and V1 Gain Using Built-in Resistor Parameter V1 gain Unit 3 times 3.5 times 4 times 4.5 times 5 times 5.5 times 6 times V1 output voltage accuracy ±2.5 ±2.5 ±2.5 ±2.5 ±2.5 ±2.5 ±2.5 % V1 maximum output voltage 9 10.5 12 13.5 15 16.5 18 V Note: The V1 maximum output voltages in Table 12 are nominal values when Tj = 25°C, and electronic potentiometer α = 0. The V1 output voltage accuracy in Table 12 are values when V1 load current I = 0 µA, 20 V is externally input to VOUT, and display is turned OFF. 33/76 FEDL9058-01 OKI Semiconductor ML9058 (b) When external resistors are used (voltage V1 adjustment internal resistors are not used) It is also possible to set the LCD drive power supply voltage V1 without using the internal resistors for voltage V1 adjustment but connecting external resistors (Ra' and Rb') between VSS & VR and between VR & V1. Even in this case, it is possible to control the LCD power supply voltage V1 and adjust the intensity of LCD display using commands if the electronic potentiometer function is used. The voltage V1 can be obtained by the following equation B-1 in the range of V1<VOUT by setting the external resistors Ra' and Rb' appropriately. V1 = (1 + (Rb'/Ra')) • VEV = (1 + (Rb'/Ra')) • (1 – (α/324)) • VREG (Eqn. B-1) External Rb' VR External Ra' VSS – V1 + VEV (Constant voltage supply + electronic potentiometer) Fig. 10 V1 voltage adjustment circuit (equivalent circuit) Setting example: Setting V1 = 7 V at Tj = 25°C When the electronic potentiometer register value is set to the middle value of (DB5, DB4, DB3, DB2, DB1, DB0) = (1, 0, 0, 0, 0, 0), the value of α will be 31 and that of VREG will be 3.0 V, and hence the equation B-1 becomes as follows: V1 = (1 + (Rb'/Ra')) • (1 – (α/324)) • VREG 7 = (1 + (Rb'/Ra')) • (1 – (31/324)) • 3.0 (Eqn. B-2) Further, if the current flowing through Ra' and Rb' is set as 5 µA, the value of Ra' + Rb' will be - Ra' + Rb' = 1.4 MΩ (Eqn. B-3) and hence, Rb'/Ra' = 1.58, Ra' = 543 kΩ, Rb' = 857 kΩ. In this case, the variability range of voltage V1 using the electronic potentiometer function will be as given in Table 13. Table 13 Example 1 of V1 variable-voltage range using electronic potentiometer function V1 Variable-voltage range Min Typ Max Unit 6.24 (α = 63) 7.0 (α = 31) 7.74 (α = 0) [V] 34/76 FEDL9058-01 OKI Semiconductor ML9058 (c) When external resistors are used (voltage V1 adjustment internal resistors are not used) and a variable resistor is also used It is possible to set the LCD drive power supply voltage V1 using fine adjustment of Ra' and Rb' by adding a variable resistor to the case of using external resistors in the above case. Even in this case, it is possible to control the LCD power supply voltage V1 and adjust the intensity of LCD display using commands if the electronic potentiometer function is used. The voltage V1 can be obtained by the following equation C-1 in the range of V1<VOUT by setting the external resistors R1, R2 (variable resistor), and R3 appropriately and making fine adjustment of R2 (∆R2). V1 = (1 + (R3 + R2 – ∆R2)/(R1 + ∆R2)) • VEV = (1 + (R3 + R2 – ∆R2)/(R1 + ∆R2)) • (1 – (α/324)) • VREG (Eqn. C-1) External R3 Rb' External R2 VR ∆ R2 – V1 + Ra' External R1 VEV (Constant voltage supply + electronic potentiometer) VSS Fig. 11 V1 voltage adjustment circuit (equivalent circuit) Setting example: Setting V1 in the range 5 V to 9 V using R2 at Tj = 25°C . When the electronic potentiometer register value is set to (DB5, DB4, DB3, DB2, DB1, DB0) = (1, 0, 0, 0, 0, 0), the value of α will be 31 and that of VREG will be 3.0 V, and hence in order to make V1 = 9 V when ∆R2 = 0Ω, the equation C-1 becomes as follows: 9 = (1 + (R3 + R2)/R1) • (1 – (31/324)) • (3.0) (Eqn. C-2) In order to make V1 = 5 V when ∆R2 = R2, 5 = (1 + R3/(R1+R2)) • (1 – (31/324)) • (3.0) (Eqn. C-3) Further, if the current flowing between VSS and V1 is set as 5 µA, the value of R1 + R2 + R3 becomesR1 + R2 + R3 = 1.8 MΩ (Eqn. C-4) and hence, R1 = 542 kΩ, R2 = 436 kΩ, R3 = 822 kΩ. In this case, the variability range of voltage V1 using the electronic potentiometer function and the increment size will be as given in Table 14. Table 14 Example 2 of V1 variable-voltage range using electronic potentiometer function and variable resistor V1 Min Typ Max Unit Variable-voltage range 4.45 (α = 63) 7.0 (α = 31) 9.96 (α = 0) [V] 35/76 FEDL9058-01 OKI Semiconductor ML9058 In Figures 10 and 11, the voltage VEV is obtained by the following equation by setting the electronic potentiometer between 0 and 63.

Also, when the voltage multiplier circuit is OFF, it is necessary to supply a voltage externally to the VOUT pin. * The pin VR is effective only when the voltage V1 adjustment internal resistors are not used (pin IRS = “L”). Leave this pin open when the voltage V1 adjustment internal resistors are being used (pin IRS = “H”). * Since the input impedance of the pin VR is high, it is necessary to take noise countermeasures such as using short wiring length or a shielded wire . * The supply current increases in proportion to the panel capacitance. When power consumption increases, the VOUT level may fall. The voltage (VOUT – V1) should be more than 3 V. • LCD Drive voltage generator circuits The voltage V1 is divided using resistors inside the IC to generate the voltages V2, V3, V4, and V5 that are necessary for driving the LCD. In addition, these voltages V2, V3, V4, and V5 are impedance transformed using voltage follower circuits and fed to the LCD drive circuits. The bias ratio of 1/9 or 1/7 can be selected using the LCD bias setting command. • At built-in power-on, and transition from power save state to display mode After built-in power-on, at the command "2F(H)" input, or on transition from power save state to display mode, the display does not operate for a maximum period of 300 ms until the built-in power is stabilized. This period of no display is not influenced by display ON/OFF command. Despite input of display ON command during this period, the display does not operate for this period. However, the command is valid. After the wait time is finished, the display operates. (During this period of no display, all commands are acceptable.) • Command sequence for shutting off the internal power supply When shutting off the internal power supply, it is recommended to use the procedure given in Fig. 12 of switching OFF the power after putting the LSI in the power save state using the following command sequence.

Column address set (Write) This command specifies the column address of the display data RAM. The column address is specified by successively writing the upper 4 bits and the lower 4 bits. Since the column address is automatically incremented (by + 1) every time the display data RAM is accessed, the MPU can read or write the display data continuously. The incrementing of the column address is stopped at the address 83(H).

A0 DB7 DB6 DB5 1 DB4 DB3 DB2 DB1 DB0 Write data Display data read (Read) This command read the 8-bit data from the specified address of the display data RAM. Since the column address is automatically incremented (by +1) after reading the data, the MPU can read successive display data from the display data RAM. Further, one dummy read operation is necessary immediately after setting the column data. The display data cannot be read out when the serial interface is being used.

When this command is issued once, the column address is not changed when the Display data read command is issued, but is incremented (by +1) only when the Display data write command is issued. This condition is maintained until the End command is issued. When the End command is issued, the column address is restored to the address that was effective at the time the Read-modify-write command was issued last. Using this function, it is possible to reduce the overhead on the MPU when repeatedly changing the data in special display area such as a blinking cursor.

This is a two-byte command consisting of the Electronic potentiometer mode set command and the Electronic potentiometer register set command, both of which should always be issued successively as a pair. • Electronic potentiometer mode set (Write) When this command is issued, the electronic potentiometer register set command becomes effective. Once the electronic potentiometer mode is set, it is not possible to issue any command other than the Electronic potentiometer register set command.

Static indicator display is controlled only by this command and is independent of all other display control commands. Since the Static indicator ON command is a two-byte command used in combination with the static indictor register set command, these two commands should always be used together.

The power save state is of two types, namely, the sleep state and the standby state, and the LSI goes into the standby state when the static indicator has been made ON. The display data and the operating mode just before entering the power save mode are retained in both the sleep state and the standby state, and also the MPU can access the display data RAM and other registers in these states. The power save mode is released by issuing the Display all-on OFF command. (See the following figure.) Static indicator OFF Static indicator ON Power save command issue (compound command) Sleep state Standby state Power save OFF command (Display all-on OFF command) Power save OFF command (Display all-on OFF command) Sleep state released Standby state released 51/76 FEDL9058-01 OKI Semiconductor ML9058 • Sleep state In this state, all the operations of the LCD display system are stopped and it is possible to reduce the current consumption to a level near the idle state current consumption unless there are accesses from the MPU. The internal conditions in the sleep state are as follows: (1) The oscillator circuit and the LCD power supply are stopped. (2) All the LCD drive circuits are stopped and the segment and common driver outputs will be at the VSS level. • Standby state All operations of the dynamic LCD display section are stopped, only the static display circuits for the indicators operate and hence the current consumption will be the minimum necessary for static drive. The internal conditions in the standby state are as follows: (1) The power supply circuit for LCD drive is stopped. The oscillator circuit will be operating. (2) The LCD drive circuits for dynamic display are stopped and the segment and common driver outputs will be at the VSS level. The static display section will be operating. Note: When using an external power supply, stop external power supply at power save start-up. For example, when providing each level of LCD drive voltage with external voltage divider, add a circuit for cutting off current flowing through the resistors of the voltage divider when initiating power save. The ML9058 has LCD display blanking control pin, DOF, which goes "L" at power save start-up. The external power supply can be stopped using DOF output. NOP (Write) This is a No Operation command.

(13) Common output state: Forward (14) Voltage V1 adjustment internal resistor ratio register: (DB2, DB1, DB0) = (1, 0, 0) (15) The electronic potentiometer register set mode is released. Electronic potentiometer register: (DB5, DB4, DB3, DB2, DB1, DB0) = (1, 0, 0 ,0, 0, 0) (16) The LCD drive method is set to the frame reversal drive. Line reversal number register: (DB4, DB3, DB2, DB1, DB0) = (1, 0, 0, 0, 0) On the other hand, when the reset command is used, only the conditions (8) to (15) above are set. As is shown in the “MPU Interface (example for reference)”, the RES pin is connected to the Reset pin of the MPU and the initialization of this LSI is made simultaneously with the resetting of the MPU. This LSI always has to be reset using the RES pin at the time the power is switched ON. Also, excessive current can flow through this LSI when the control signal from the MPU is in the high impedance state. It is necessary to take measures to ensure that the input pins of this LSI do not go into the high impedance state after the power has been switched ON. When the built-in LCD drive power supply circuit of the ML9058 is not used, it is necessary that RES = “L” when the external LCD drive power supply goes ON. During the period when RES = “L”, although the oscillator circuit is operating, the display timing generator would have stopped and the pins CL, FR, FRS, and DOF would have been tied to the “H” level. There is no effect on the pins DB0 to DB7. 53/76 FEDL9058-01 OKI Semiconductor ML9058 EXAMPLES OF SETTINGS FOR THE INSTRUCTIONS When using the internal power supply immediately after power-on VDD-VSS Power supply ON when the pin RES = “L” Power supply stabilization Release reset state (RES Pin = “H”) Initial settings state (default) *1 Function setting using command input (user settings) *2 LCD bias set *3 ADC select *4 Common output state select *5 Line reversal/frame reversal drive select *(a) Function setting using command input (user settings) Setting voltage V1 adjustment internal resistor ratio *6 Electronic potentiometer *7 Function stabilization using command input (user settings) Power control set *8 Wait for more than 300 ms *(b) Initial setting state complete *(a): Carry out power control set within 5ms after releasing the reset state.

Function description “Power supply circuit” If the power supply of this LSI is switched OFF when the internal power supply is still ON, since the state of supplying power to the built-in LCD drive circuits continues for a short duration, it may affect the display quality of the LCD panel. Always follow the power supply switching OFF sequence. Description of operation “Power save” Refresh Although the ML9058 holds operation state by commands, excessive external noise might change the internal state. On a chip-mounting and system level, it is necessary to take countermeasures against preventing noise from occurring. It is recommended to use the refresh sequence periodically to control sudden noise. Refresh sequence Set to the state in which all commands have been set.

Further, by using the serial interface, it is possible to operate the LSI with a minimum number of signal lines. In addition, it is possible to expand the display area by using the ML9058 series LSIs in a multiple chip configuration. In this case, it is possible to select the individual LSI to be accessed using the chip select signals. • 80-Series MPU VDD A0 A1 to A7 MPU IORQ Decoder VDD C86 CS2 DB0 to DB7 DB0 to DB7 GND A0 CS1 RD RD WR WR RES RES RESET ML9058 VCC P/S VSS VSS • 68-Series MPU VDD A0 A1 to A15 MPU VMA Decoder DB0 to DB7 VDD E R/W RES C86 CS2 DB0 to DB7 E GND A0 CS1 R/W RES RESET ML9058 VCC P/S VSS VSS • Serial interface VDD GND Port 3 Port 4 A0 CS1 Port 5 CS2 Port1 SI Port2 RES SCL RES RESET VDD C86 Can be tied to either level.
