SED1565 Series

GENERAL DESCRIPTION

The SED1565 Series is a series of single-chip dot matrix liquid crystal display 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 liquid crystal drive signal independent of the microprocessor. Because the chips in the SED1565 Series contain 65 × 132 bits of display data RAM and there is a 1-to-1 correspondence between the liquid crystal panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The SED1565 Series chips contain 65 common output circuits and 132 segment output circuits, so that a single chip can drive a 65 × 132 dot display (capable of displaying 8 columns × 4 rows of a 16 × 16 dot kanji font). The SED1567 Series chips contain 33 common output circuits and 132 segment output circuits, so that a single chip can drive 33 × 132 dot display (capable of displaying 8 columns × 2 rows of 16 × 16 dot kanji fonts). Thanks to the built-in 55 common output circuits and 132 segment output circuits, the SED1568*

** is

capable of displaying 55 × 132 dots (11 columns × 4 lines using 11 × 12 dots Kanji font) with a single chip. The SED1569 Series chips contain 53 common output circuits and 132 segment output circuits, so that a single chip can drive 53 × 132 dot display (capable of displaying 11 columns × 4 rows of 11 × 12 dot kanji fonts). 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 lowpower liquid crystal driver power supply, resistors for liquid crystal driver power voltage adjustment and a display clock CR oscillator circuit, the SED1565 Series chips can be used to create the lowest power display system with the fewest components for highperformance portable devices.

D7 to D0 I/O This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit 8

standard MPU data bus. (SI) When the serial interface is selected (P/S = “L”), then D7 serves as the (SCL) serial data input terminal (SI) and D6 serves as the serial clock input

terminal (SCL). At this time, D0 to D5 are set to high impedance.

When the chip select is inactive, D0 to D7 are set to high impedance. A0 I This is connect to the least significant bit of the normal MPU address bus, 1

and it determines whether the data bits are data or a command.

A0 = “H”: Indicates that D0 to D7 are display data.

A0 = “L”: Indicates that D0 to D7 are control data. RES I When RES is set to “L,” the settings are initialized. 1

The reset operation is performed by the RES signal level. CS1 I This is the chip select signal. When CS1 = “L” and CS2 = “H,” then the 2

CS2 chip select becomes active, and data/command I/O is enabled. RD I • When connected to an 8080 MPU, this is active LOW. 1

(E) This pin is connected to the RD signal of the 8080 MPU, and the

SED1565 series data bus is in an output status when this signal is “L”.

• When connected to a 6800 Series MPU, this is active HIGH. This is the 68000 Series MPU enable clock input terminal.

WR I • When connected to an 8080 MPU, this is active LOW. 1 (R/W) This terminal connects to the 8080 MPU WR signal. The signals on

the data bus are latched at the rising edge of the WR signal.

• When connected to a 6800 Series MPU: This is the read/write control signal input terminal. When R/W = “H”: Read. When R/W = “L”: Write.

C86 I This is the MPU interface switch terminal. 1

C86 = “H”: 6800 Series MPU interface. C86 = “L”: 8080 MPU interface.

P/S I This is the parallel data input/serial data input switch terminal. 1

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 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.

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 SED1565 Series chips 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.

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 SED1565 Series. Wait time may not be considered. And, in the SED1565 Series chips, each time data is sent

is performed through the bus holder attached to the 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.

Display Data RAM

The display data RAM is a RAM that stores the dot data for the display. It has a 65 (8 page x 8 bit +1) x 132 bit structure. It is possible to access the desired bit by specifying the page address and the column address. Because, as is shown in Figure 3, the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction, there are few constraints at

The Page Address Circuit

As shown in Figure 6-4, 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 the page for the RAM region used only by the indicators, and only display data D0 is used.

The Column Addresses

As is shown in Figure 4, 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 incrementation 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 respecify 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.

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 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 SED1565 Series, COM47 output for SED1566 Series and COM31 output for the SED1567 Series when the common output mode is reversed. The display area is a 65 line area for the SED1565 Series, a 49 line are for the SED1566 and a 33 line area for the SED1567 Series from the display start line address. If the line addresses are changed dynamically using the display start line address set command, screen scrolling, page swapping, etc. can be performed.

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.

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.

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 display clock is input through the CL terminal.

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.

The combination of the display data, the COM scan signal, and the FR signal produces the liquid crystal drive voltage output. Figure 6 shows examples of the SEG and COM output wave form.

The Power Supply Circuits

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers. They comprise 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 of 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 Voltage Regulator Circuit

The step-up voltage generated at VOUT outputs the liquid crystal driver voltage V

5 through the voltage

regulator circuit. Because the SED1565 Series chips have an internal high-accuracy fixed voltage power supply with a 64level 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. Moreover, in the SED1565 Series, three types of thermal gradients have been prepared as V

REG options: (1)

approximately -0.05%/°C (2) approximately -0.2%/°C, and (3) external input (supplied to the V

RS 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 V

5 can be controlled by

commands alone (without adding any external resistors), making it possible to adjust the liquid crystal display brightness. The V

5 voltage can be calculated using

equation A-1 over the range where | V5 | < | VOUT |.

* Because the input impedance of the V

R terminal is left open.

R terminal is

high, it is necessary to take into consideration short leads, shield cables, etc. to handle noise.

The Liquid Crystal Voltage Generator Circuit

The V

5 voltage is produced by a resistive voltage

divider within the IC, and can be produced at the V1, V2,

3, and V4 voltage levels required for liquid crystal

V driving. Moreover, when the voltage follower changes the impedance, it provides V

1, V2, V3 and V4 to the

liquid crystal drive circuit. 1/9 bias or 1/7 bias for SED1565 Series, 1/8 bias or 1/6 bias for SED1566 Series and 1/6 bias or 1/5 bias for the SED1567 Series can be selected.

High Power Mode

The power supply circuit equipped in the SED1565 Series 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 22 is recommended for shutting down the internal power supply, first placing the power supply in power saver mode and then turning the power supply OFF.

Example of the Process by which to Determine the Settings:

• Determine C2 by displaying an LCD pattern with a heavy load (such as horizontal stripes) and selecting a C2 that stabilizes the liquid crystal drive voltages (V

value.

• Next turn all the power supplies ON and determine C1.

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 overcurrent 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 SED1565D SED1568D

BB and SED1569DBB, it is necessary that

BB, SED1566DBB, SED1567DBB,

RES is “H” when the external liquid crystal power supply is turned on. This IC has the function to discharge V supply short-circuits to V

5 when RES is “L,” and the external power

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 SED1565 series, it is necessary that RE 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.

COMMANDS

The SED1565 Series chips 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. (See “10. Timing Characteristics” regarding the timing.) 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>

This command specifies the page address corresponding to the low address when the MPU accesses the display data RAM (see Figure 4). 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. See the page address circuit in the Function Description (page 1–20) for the detail.

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.

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.

Display Data Read

This command reads 8-bit data from the specified display data 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.

Read/Modify/Write

This command is used paired with the “END” command. Once this command has been input, the display data read command does not change the column address, but only the display data write command increments (+1) the column address. This mode is maintained until the END command is input. When the END command is input, the column address returns to the address it was at when the read/modify/write command was entered. This function makes it possible to reduce the load on the MPU when there are repeating data changes in a specified display region, such as when there is a blanking cursor.

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. This mode is cleared when data is set in the register by the static indicator register set command.

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 26 for power save off sequence.

• 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

DD level. The static drive system does not operate.

a V 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 SED1565 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.

Notes and Cautions

1. The V

2. Insure that the voltage levels of V

SS2, V1 to V5 and VOUT are relative to the VDD = 0V reference.

1, V2, V3, and V4 are always such that VDD ≥ V1 ≥ V2 ≥ V3 ≥ V4 ≥ V5.

3. Permanent damage to the LSI may result if the LSI is used outside of the absolute maximum ratings. Moreover, it is recommended that in normal operation the chip be used at the electrical characteristic conditions, and use of the LSI outside of these conditions may not only result in malfunctions of the LSI, but may have a negative impact on the LSI reliability as well.

THE MPU INTERFACE (REFERENCE EXAMPLES)

The SED1565 Series can be connected to either 80 × 86 Series MPUs or to 68000 Series MPUs. Moreover, using the serial interface it is possible to operate the SED1565 series chips with fewer signal lines. The display area can be enlarged by using multiple SED1565 Series chips. When this is done, the chip select signal can be used to select the individual ICs to access.
