GG EE NN EE RR AA LL DD EE SS CC RR IIPP TTIIOO NN ST7565P 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 this chip generates LCD driving signals independent of the microprocessor. Each data bits (65x132) of the internal Display Data RAM is 1-to-1 correspondence with each pixels (65x132) on the LCD panel, therefore, ST7565P enables displays with a high degree of freedom. Moreover, the display area can be extended horizontally by using Master/Slave feature. With the abundant embedded circuits (2~6 times booster circuit, V0 regulator with contrast control for LCD voltage adjustment, voltage follower with bias selection and R-C oscillation circuit), ST7565P can be used to create a display system with the lowest power consumption and the fewest external components for high-performance portable devices.

Ver 2.1b 24/71 2009/09/14 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 ST7565P 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 ST7565P. Wait time may not be considered. And, in the ST7565P, 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 2.1b 25/71 2009/09/14 The Busy Flag When the busy flag is “1” it indicates that the ST7565P 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 2.1b 28/71 2009/09/14 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 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.

Ver 2.1b 33/71 2009/09/14 The Voltage Regulator Circuit The step-up voltage generated at VOUT outputs the LCD driver voltage V0 through the voltage regulator circuit. Because the ST7565P chips have an internal high-accuracy fixed voltage power supply with a 64-level electronic volume function and internal resistors for the V0 voltage regulator, systems can be constructed without having to include high-accuracy voltage regulator circuit components. (VREG thermal gradients approximate -0.05%/° C) (A) When the V0 Voltage Regulator Internal Resistors Are Used Through the use of the V0 voltage regulator internal resistors and the electronic volume function the liquid crystal power supply voltage V0 can be controlled by commands alone (without adding any external resistors), making it possible to adjust the liquid crystal display brightness.

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 V0 through commands. In the range where | V0 | < | VOUT |, the V0 voltage can be calculated using equation B-1 based on the external resistances Ra’ and Rb’.

In this case, the use of the electronic volume function makes it possible to control the liquid crystal power supply voltage V0 by commands to adjust the liquid crystal display brightness. In the range where | V0 | < | VOUT | the V0 voltage can be calculated by equation C-1 below based on the R1 and R2 (variable resistor) and R3 settings, where R2 can be subjected to fine adjustments ( Δ R2).

Ver 2.1b 38/71 2009/09/14 * When the V0 voltage regulator internal resistors or the electronic volume function is used, it is necessary to at least set the voltage regulator circuit and the voltage follower circuit to an operating mode using the power control set commands. Moreover, it is necessary to provide a voltage from VOUT when the Booster circuit is OFF. * The VR terminal is enabled only when the V0 voltage regulator internal resistors are not used (i.e. the IRS terminal = “L”). When the V0 voltage regulator internal resistors are used (i.e. when the IRS terminal = “H”), then the VR 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 The V0 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, when the voltage follower changes the impedance, it provides V1, V2, V3 and V4 to the liquid crystal drive circuit. High Power Mode The power supply circuit equipped in the ST7565P chips has very low power consumption (normal mode: HPM = “H”). However, for LCD panels with large loads (size), this low-power power supply may cause display quality to degrade. When this occurs, set the HPM terminal to “L” (high power mode) can improve the display quality. SITRONIX recommends that the display should 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 power supply in power saver mode and then turning the power supply OFF.

Select a value that will stabilize the liquid crystal drive voltage. Example of the process which determines the capacitor values: * Turn the voltage regulator circuit and voltage follower circuit ON and supply a voltage to VOUT from the outside. * 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 (V0 to V4). Note that all C2 capacitors must have the same capacitance value. * Next turn all the power supplies ON and determine C1.

V0 voltage regulator internal resistor ratio set mode clear 17. Clear Electronic volume register : 18. Test mode clear On the other hand, when the reset command is used, the above default settings from 11 to 18 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 ST7565P,it is necessary that /RES is “H” when the external liquid crystal power supply is turned on. This IC has the function to discharge V0 when /RES is “L,” and the external power supply short-circuits to Vss when /RES is “L.” This means that an internal resistor is connected between VSS and V0. While /RES is “L,” the oscillator works but the display timing generator stops, and the CL, FR and /DOF terminals are fixed to “H.” The terminals D0 to D7 are not affected. The VSS level is output to SEG and COM output terminals after a success hardware reset.

Ver 2.1b 42/71 2009/09/14 CC OO MM MM AA NN DD SS The ST7565P 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.

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.

Ver 2.1b 43/71 2009/09/14 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.

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 2.1b 44/71 2009/09/14 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. 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 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.
