DESCRIPTION OF FUNCTIONS 3.1 CPU Interface 3.1.1 Selection of interface type The PD16686, 16687 chips transfer data using an 8-bit bidirectional data bus (D7 to D0) or a serial data input (SI). Setting the polarity of the PSX pin as either H (high) or L (low) selects between 8-bit parallel or serial data input, as shown in the following table. PSX H: Parallel input L: Serial input CS CS CS RS RS RS /RD /RD Note1 /WR /WR Note1 C86 C86 Note1 D7 D7 SI D6 D6 SCL D5 to D0 D5 to D0 Hi-ZNote2 Notes 1. Fixed as either H or L 2. Hi-Z: High impedance 3.1.2 Parallel interface When the parallel interface has been selected (PSX = H), setting the C86 pin as either H or L enables a direct connection to an i80 series or M68 series CPU (see table below). C86 H: M68 series CPU L: i80 series CPU CS CS CS RS RS RS /RD E /RD /WR R,/W /WR D7 to D0 D7 to D0 D7 to D0 The data bus signal is identified according to the combination of the RS, /RD(E), and /WR(R,/W) signals, as shown in the following table.

The data is output to the data bus when the /RD signal is L. Figure 3-1. i80 Series Interface Data Bus Status /CS1 (CS2=H) /WR /RD Hi-Z DBn Data write Valid data Data Read Hi-Z (2) M68 series parallel interface When M68 series parallel data transfer has been selected, data is written at the falling edge of the E signal when the R,/W signal is L. During the data read operation, the data bus enters the output status when the R,/W signal is H, outputs valid data at the rising edge of the E signal, and enters the high-impedance state at the falling edge of the R,/W signal (R,/W = L) Figure 3-2. M68 Series Interface Data Bus Status /CS1 (CS2=H) R,/W E Hi-Z DBn Invalid data Valid data Hi-Z Data Sheet S15548EJ1V0DS 21 PD16686, 16687 3.1.3 Serial interface When the serial interface has been selected (PSX = L), if the chip is active (/CS1 = L, CS2 = H), serial data input (SI) and serial clock input (SCL) can be received. Serial data is read from D7 and then from D6 to D0 on the rising edge of the serial clock, via the serial input pin. This data is synchronized on the eighth serial clock's rising edge and is then converted to parallel data for processing. RS input is used to judge serial input data as display data or command data: when RS = H the data is display/command data and when RS = L the data is index data. When the chip enters active mode, RS input is read at the rising edge after every eighth serial clock and is then used to judge the serial input data. The serial interface signal chart is shown below. Figure 3-3.

If the chip is not active, the shift register and counter are reset to their initial settings. 2. The data read function is disabled during serial interface mode. 3. When using SCL wiring, take care concerning the possible effects of terminating reflection and noise from external sources. NEC recommends checking operation with the actual device. 3.1.4 Chip select The PD16686, 16687 have two chip select pins (/CS1 and CS2). The CPU parallel interface or serial interface can be used only when /CS1 = L and CS2 = H. When chip select is inactive, D0 to D7 are set to high impedance (invalid) and input of RS, /RD, or /WR is not active. If serial interface mode has been set, the shift register and counter are both reset. 3.1.5 Display data RAM and on-chip register access Because only the required cycle time (tcyc) is saisfied when accessing the PD16686, 16687 from the CPU, high-speed data transfer is possible. There is no need to consider any wait time. No dummy data is needed when writing data. Even when data is read, there is no need for dummy data except in the display memory access register (R11). In other words, dummy data is required only when reading data from the display memory access register (R11). Figure 3-4 illustrates this relationship. 22 Data Sheet S15548EJ1V0DS PD16686, 16687 Figure 3-4.

The RAM configuration is 256 bits (32 x 8 bits) x 128 bits. Any specified bit can be accessed by selecting the corresponding X address and Y address. In the data sent from the CPU, D0 to D7 corresponds to SEGx on the LCD display (see Figure 3-5). The CPU writes data to and reads data from the display RAM via the I/O buffer, and these read/write operations are independent of the signal read operations for the LCD driver. Accordingly, there are no adverse effects (such as flicker) in the LCD display when display data RAM is accessed asynchronously. Figure 3-5.

When using X address increment mode (INC = 0: control register 2 (R1)), the specified X address is incremented (by 1) each time a display data read or write operation is executed. The CPU is able to continuously access the display data. The X address is incremented to 1FH, after which the Y address is incremented after each read or write operation and the X address is set back to 00H. For monochrome (black-and-white) display, the X address is incremented to 0FH, after which the Y address is incremented after each read or write operation and the X address is set back to 00H. 3.2.3 Column address circuit When displaying the contents of the display data RAM, the column address corresponds to the SEG output, as shown in Figure 3-6. Similarly, the static icon address corresponds to the PSEG output. As is shown in Tables 3-1 and 3-2, the correspondence between the display RAM's column address and segment output can be inverted using the ADC flag in control register 1 (R0) (segment driver direction selection flag). This reduces the constraints on chip layout when assembling the LCD module. Table 3-1.

When using Y address increment mode (INC = 1: control register 2 (R1)), the specified Y address is incremented (by 1) each time a display data read or write operation is executed. The CPU is able to continuously access the display data. The Y address is incremented to 7FH, after which the X address is incremented after each read or write operation and the Y address is set back to 00H. 3.2.5 Common scan circuit The common scan circuit sets the scan lines for common signals. The scan direction is set using the COMR flag in control register 1 (R0), as shown in Table 3-3. For example, when using 1/80 duty, when COMR = L the scan direction is COM1 COM80 and when COMR = H, the scan direction is COM80 COM1 using the COM80 to COM1 pins. Table 3-3.

The display start line set (R12) is used to specify the top line in the display. The screen can be scrolled, overwritten, etc. A 7-bit display start address is set to the display start line register. 3.2.7 Display data latch circuit The display data latch circuit is used for temporary storage of data that is output to the LCD driver from the display data RAM. The display scan command that sets normal or reverse display mode and the display ON/OFF command control latched data so that there is no effect on the data in the display data RAM. 28 Data Sheet S15548EJ1V0DS PD16686, 16687 3.3 Blink/Reverse Display Circuit The PD16686, 16687 enable blinking display and reverse display in designated parts of the full dot display. A blinking display is achieved by cycling ON/OFF (level 0 when four-level gray scale mode has been selected) at approximately 1 Hz and reverse display is achieved by inverting the display level value. The area designated for blinking is specified via the blink start/end line address registers (R14 and R15), the blink X address register (R13), and the blink data memory (R16). First, the blinking display's start and end line addresses are selected via the blink start/end line address registers. Next, the blink X address register (R13) and the blink data memory (R16) are used to select the column for the blinking display. The inversion start/end line address registers (R18 and R19), the inverted X address register (R17), and inverted data memory (R20) are used to select the reverse display area. First, the inversion start/end line address registers (R18 and R19) are set to select the line addresses where the reverse display will start and end. Next, the inverted X address register (R17) and the inverted data memory (R20) are used to select the column for the reverse display. The specified blink/inverted X address is incremented (by 1) with each input of blink/reverse display data. The blink RAM and inversion RAM, which have a 128 bit (16 x 8 bit) configuration, are used to store data for blinking display and reverse display respectively. To access the desired bit, simply specify the corresponding X address. The blink/reverse data (data bits D0 to D7 sent from the CPU) correspond to SEGx on the LCD display, as shown in Figure 3-7. After the area and data settings are complete, the BLD bit and IVD bit in the control register 1 (R0) are set to H, at which point the blinking and/or reverse display of data begins. Figure 3-8 illustrates the relationship between the start line address, end line address, blink/reverse data, and LCD display. Table 3-4.

The clocks from this oscillator are controlled via the CLS pin and the DTY flag in the control register 2 (R1). The clock configuration for the display can be set to suit the target system. The functions of this circuit are described below. *The oscillator for normal and partial display is enabled only when resistors RN and RP have been connected. The DTY flag in the control register 2 (R1) and the CLS pin status are used to switch between the oscillation clocks for normal display and partial display modes. *The divider divides the external clock that has been input for the normal oscillator and the normal display into a clock for partial display. The external clock that is input for the partial oscillator and partial display is also divided for the partial display. *The division level is automatically set for the divider based on the relationship between the ON/OFF status of the divider setting pin (CLS pin) and the duty of the specified partial display, as shown in Table 3-5.

Display data is latched into the display data latch circuit in synch with the display clock and is output via segment driver output pins. Reading of the display data is completely independent of the CPU's accessing of the display data RAM. Consequently, there are no adverse effects (such as flicker) on the LCD panel even when the display data RAM is accessed asynchronously in relation to the LCD contents. The internal common timing is generated from the display clock. As shown in Figure 3-11, a driver waveform based on the frame AC drive method is generated for the LCD driver.

It includes a booster, voltage regulator, and voltage follower. In the power supply circuit, the power system control 1 (R32) is used to control the ON/OFF status of the power supply circuit's booster, voltage regulator (also called V regulator), and voltage follower (V/F). This makes it possible to jointly use an external power supply together with certain functions of the on-chip power supply. Table 3-7 shows the function that controls the 3-bit data in the power system control 1 (R32) and Table 3-7 shows a reference chart of combinations. Table 3-7.

Since the booster uses signals from the on-chip oscillator, either the oscillator must be operating or a display clock must be input from an external source. The booster uses pins C1+, C1- to C9+, C9- for normal boost and pins C1A and VDD2 for boost regulation. The wire impedance should be kept as low as possible. The number of boost levels is set using the FBS2, FBS1, and FBS0 flags in power system control 3 (R34), as shown in Table 3-9. Caution If a capacitor is connected to a boost-related system pin that is not for one of these set boost levels, current consumption may increase. Therefore, do not connect any capacitors beyond the number of set boost levels. This also applies for the CA1 pin, used to regulate the boost levels. Figure 3-12 describes the connection method for boost levels and capacitors. The partial booster is settings are made using the BST1 and BST0 flags in the power system control 3 (R34), as shown in Table 3-10. Data Sheet S15548EJ1V0DS 37 PD16686, 16687 Figure 3-12.

Since the PD16686, 16687 has a 256-step electronic volume function and an on-chip resistor for VLCD voltage regulation, a small number of components can be used to configure a highly accurate voltage regulator. (1) When using an on-chip resistor for VLCD voltage regulation The on-chip resistor for VLCD voltage regulation and the electronic volume function can be used to regulate the contrast of the LCD contents by controlling the LCD drive voltage VLCD using commands only. In such cases, no external resistor is needed. If VLCD < VOUT, then the value for VLCD can be determined from the following equation. Example Equation VLCD < VOUT VLCD = (1 + Rb ) VEV Ra VLCD = (1 + Rb ) (1 - ) VREG Ra 384 Remark VEV = (1 - ) VREG 384 Figure 3-13. When Using On-Chip Resistor for VLCD Voltage Regulation VEV (Constant voltage source + electronic volume) + VLCD Rb Ra VREG is the IC's on-chip constant voltage source, for which three types of temperature characteristic curves are available. These temperature characteristic curves can be adjusted via settings in the power system control 1 (R32) (TSC1, TCS0), as shown in Table 3-11. Table 3-11 shows the VREG voltage when TA = 25C.

This factor can be controlled at eight levels based on settings in power control 2 (R33) ([VRR2, VRR1, VRR0]: normal display mode and [PVR2, PVR1, PVR0]: partial display mode). Reference voltage values (1 + Rb/Ra) are determined based on 4-bit data set to VLCD's on-chip resistance factor register, as shown in Table 3-13. Table 3-13.

In such cases, the electronic volume function can be used to control the LCD drive voltage VLCD and to regulate the contrast of the LCD contents via commands. In addition, the PD16686, 16687 enable selection between two display values (for normal display and partial display). The value is set using an external division resistor and is automatically selected by the DTY flag in the control register 2 (R1). The VLCD value can be determined using Example 1 (DTY = 0) and Example 2 (DTY = 1) if it is within the range of VLCD < VOUT. Example 1.

In such cases, the display quality and power consumption level can be improved by setting. The HPM1 and HPM0 flags in the power system control 1(R32) to "0, 1" to "1, 1" to switch to the op amp driver capacity for mode settings shown in Table 3-14. Check the actual display quality before deciding which mode to set. If setting high power mode still does not sufficiently improve the display quality, the LCD drive voltage must be provided from an external power source. Table 3-14.

The full dot driver has a 33-level gray-scale palette (eight levels of pulse width modulation plus four-frame rate control), from which four levels of gray scale can be selected and registered as the IC's output gray-scale palette. The icon driver has a gray-scale palette with 32-level pulse width modulation, from which four levels of gray scale can be selected and registered for use as the IC's output gray-scale palette. 3.7.1 Full-dot pulse width modulation The PD16686, 16687's pulse width modulator divides the normal LCD display signal's segment pulse width by eight and outputs in synch with the dot output timing based on the ratio (1/8 to 8/8 pulses) for the gray-scale palette that has been selected via a command.

In normal display mode, the AC driver inversion cycle can be set for any number of inverted (reverse display) lines listed in Table 3-18, based on the NID6 to NID0 bit settings in the AC driver inversion cycle register (R6). If the screen display size has been changed via settings made in the duty setting register (R5), the NIDn values are automatically overwritten by values from the corresponding DTYn bits. The shift amount for each displayed frame can be set as shown in Table 3-19 via settings made to bits MSD6 to MSD0 in the AC driver inversion position shift register (R7). Table 3-18.

Display size (duty) AC inversion cycle AC inversion shift amount Caution Setting a small inversion cycle will cause a reduction in the IC's display drive capacity and an increase in the current consumption. NEC therefore recommends determining the inversion cycle after making a thorough evaluation of the actual LCD panel. Data Sheet S15548EJ1V0DS 55 PD16686, 16687 3.8 Display Modes 3.8.1 Partial display mode The PD16686, 16687 include a function for outputting a display that uses only part of the LCD panel. The duty setting for partial display mode can be selected as 1/12, 1/25, or 1/38. Parts of the LCD panel that are outside of the specified display area are scanned with non-select waveforms. The partial start line address register (R21) is used to select which part of the LCD panel to use for the partial display. The display area starts from the start line address and includes the number of lines (12, 25, or 38 lines) that has been specified via the partial display mode setting (R10). When entering this mode, the booster is set to the boost level number that has been set via the power system control 3 (partial display boost register) (R34) and the display start line is fixed as 00H. In addition, the bias level is automatically changed to the value that has been set via the partial display mode setting (R10). The relationship between the oscillator's frequency and the frame frequency in partial mode is also automatically changed. Figure 3-24 shows the mutual relationship between the partial line start address and the LCD display. When using the partial display mode, the blinking and reverse display functions can be used in the same way as during full-dot display mode. Caution The LCD driver voltage is lower in partial display mode, because the duty is lower than in normal display mode. There may be restrictions on the useble duty depending on the LCD panel characteristics. We recommend determining the partial duty after making a thorough evaluation of the actual LCD panel. Figure 3-24. Relationship Between Partial Line Start Address and LCD Display (in Partial Display Mode) 00H 01H 02H 03H ... 1DH 1EH 1FH Display start line (00H) Partial display start line 12, 25, or 38 lines Non-display areas Caution In partial display mode, the display start line setting (R12) command is ignored. When switching from normal display mode to partial display mode or from partial display mode to normal display mode, if an electric charge remains in the smoothing capacitor that is connected between the LCD drive voltage pins (VLCD to VLC4) and the VSS pin, abnormalities such as a brief all-black display may occur during the mode switching operation. To avoid such abnormalities, we recommend using the following power-on sequence. 56 Data Sheet S15548EJ1V0DS PD16686, 16687 Normal display partial display switch sequence DISP = 0 HPM1 = 1, HPM0 = 0 R0 Display OFF R32 High power mode settings Switch display mode R1 Control register 2: switch DTY flag Wait time HPM1 = X, HPM0 = X DISP = 1 700 ms (stabilization time for LCD drive voltage and booster)Note R32 High power mode settings (to mode used during normal display) R0 Display ON, internal operations status Note This 700 ms wait time indicates the time for the VLCD level to change from 15 to 6 V and thus varies according to the panel characteristics and the capacitance value of the boost/smoothing capacitor.

Data Sheet S15548EJ1V0DS 57 PD16686, 16687 3.8.2 Monochrome (black/white) display The PD16686, 16687 provide both a four-level gray scale display mode and a monochrome display mode. To switch to the monochrome display mode, set GRAY = H. The display RAM for one screen of monochrome display mode contents is configured as 128 bits x 128 bits (16 x 8 bits). When using these IC's in monochrome display mode, two screens of data can be written to the display RAM and the two screens can be switched by setting the DSEL bit in the control register 2 (R1). Screen 1 is displayed on the LCD panel when DSEL = L and screen 2 is displayed when DSEL = H. When writing data, the display RAM uses the same X address (00H to 0FH) and Y address and the BWW bit value in the control register 2 (R1) determines which of the two screens the data will be written to: when BWW = L, data is written to screen 1 and when BWW = H, data is written to screen 2, as shown in Figure 3-25. When accessing a specified bit, specify both the X address and Y address. The display data in D0 to D7 (sent from the CPU) corresponds to the SEGx portions of the LCD display, as shown in Figure 3-26. Figure 3-27 shows the relationship between the display data in monochrome display mode and the page/column addresses. Figure 3-25.

Icons are static-driven and their contrast can be adjusted at 32 levels using phase modulation. The static icon data RAM (R41) that is used to record icon display data contains display data (DIS) and blink data (BRI) in a 20-bit x 2 configuration, as shown in Table 3-22 (where ADC = 0) and Table 3-23 (where ADC = 1). Addresses in the static icon data RAM are specified via the static icon address register (R40) and then data is written to memory. The icon blink function operates only when the display data setting is 1, the blink data setting is 1, and the IBL setting is also 1 (R1). Table 3-22.

The pulse width of the ON signal that is output in static drive mode is divided into 32 levels (1/32 to 32/32 pulse width) and the dot output's timing changes during output according to the phase modulation ratio recorded in bits ICS4 to ICS0 of the static icon contrast (R42), as shown in Table 3-24.

Use the reset command to reset if the memory contents need to be retained. Cautions 1. Using the /RES pin to reset initializes the shift clock counter. 2. Always input the reset command as the first command after power application . 62 Data Sheet S15548EJ1V0DS PD16686, 16687 4. COMMANDS The PD16686, 16687 chips use a combination of RS, /RD (E), and /WR (R,/W) signals to identify data bus signals. Command interpretation and execution is performed using internal timing that does not depend on any external clock. Therefore, processing is very fast and there is usually no need to check for a busy status. The i80 series CPU interface activates read commands using a low pulse input to the /RD pin and activates write commands using a low pulse input to the /WR pin. The M68 series CPU interface sets read mode using a high level input to the R,/W pin and sets write mode using a low level input to the same pin. It activates both read and write commands using a high-level pulse input to the E pin. Thus, the M68 series CPU interface differs from the i80 series CPU interface in that /RD (E) is at high level during status read and display data read operations, as shown in the following command descriptions and command table. Command descriptions using an i80 series CPU interface are shown below. If the serial interface has been selected, data is input sequentially starting from D7.

CPU INTERFACE (REFERENCE EXAMPLE) The PD16686, 16687 can be connected to either an i80 series CPU or an M68 series CPU. Also, if a serial interface connection is used, the number of signal lines can be reduced. If several PD16686, 16687 chips are used, the display area can be enlarged. When using this method, use the chip select signal to select and access the ICs.

Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it. 2 HANDLING OF UNUSED INPUT PINS FOR CMOS Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 STATUS BEFORE INITIALIZATION OF MOS DEVICES Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function. Data Sheet S15548EJ1V0DS 99 |
