data sheet s13368ej4v0ds 14 pd16682 5.1.3 serial interface if the serial interface has been selected (p,/s = l) and if the chip is in the active state (/cs1 = l and cs2 = h), both serial data input (si) and serial clock input (scl) can be received. the serial interface includes an 8-bit shift register and a 3-bit counter. serial data is captured at the rising edge of the serial clock and is clocked in via the serial data input pins in sequence from d 7 to d 0 . at the rising edge of the eighth serial clock, data is converted to 8-bit parallel data. input via the a0 pin can be used to determine whether the input serial data is display data or a command (display data when a0 = h, command when a0 = l). the timing for reading and identifying input via a0 occurs at the rising edge of the ? eighth x n ? serial clock once the chip ? s status is active. a serial interface signal chart is shown below. figure 5 ? ? ? ? 3. serial interface chart d 7 d 6 d 5 d 4 d 3 d 2 d 1 d 0 d 7 d 6 d 5 d 4 d 3 d 2 d 1 d 0 d 7 d 6 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 /cs1 si scl a0 cs2 remarks1. when the chip ? s status is inactive, the shift register and counter are both reset to their initial values. 2. data cannot be read when using the serial interface. 3. for the scl signal, caution is advised concerning the wire ? s terminating reflection and noise from external sources. we recommend to check the operation on the actual equipment. 5.1.4 chip select the pd16682 has two chip select pins (/cs1 and cs2). the mpu interface or serial interface can be used only when /cs1 = l and cs2 = h. when the chip select pin is inactive, d 7 to d 0 are set to high impedance (invalid) and input of a0, /rd, or /wr is invalid. if the serial interface has been selected, the shift register and counter are both reset. 5.1.5 display data ram and internal register access access to the pd16682 from the mpu supports high-speed data transfers since the cycle time (t cyc ) is met and there is no need for wait time. when data transfer occurs between the pd16682 and the mpu, the data is held in a bus holder belonging to the internal data bus and is written to the display data ram before the next data write cycle. when the mpu reads the contents of the display data ram, the data read during the first data read cycle (dummy cycle) is first held in the bus holder and is read from the bus holder to the system bus during the next data read cycle. note with caution that, due to constraints on the read sequence for the display data ram, when the address is set, the data is not output from the address specified by the next read command but rather is output to the address specified during the second data read operation. consequently, one dummy read operation is strictly required after setting an address or after a write cycle. figure 5 ? 4 illustrates this situation.

data sheet s13368ej4v0ds 16 pd16682 6. display data ram 6.1 display data ram this is the ram that is used to store the display ? s dot data. the ram configuration is 65 (8 pages x 8 bits + 1) x 132 bits. any specified bit can be accessed by selecting the corresponding page address and column address. as is shown in figure 6 ? 1 below, the display data (d 7 to d 0 ) from the mpu corresponds to the common direction in the lcd, so that if a multiple set of pd16682 chips is used, there are fewer constraints on transfers of display data and relatively more freedom for display configurations. the mpu accesses the display data ram for read/write operations via the i/o buffer, and these operations are independent of the lcd driver signal read operations. therefore, there are absolutely no adverse effects (such as flicker) in the display when display data ram is accessed asynchronously in relation to the lcd contents. figure 6 ? ? ? ? 1. lcd data and lcd display lcd data lcd display d 0 0111 0 com 0 d 1 1000 0 com 1 d 2 0000 0 com 2 d 3 0111 0 com 3 d 4 1000 0 com 4 ... ... 6.2 page address circuit the page address set command specifies the page address in the display data ram, as is shown in figure 6 ? 2. to access a different page, simply specify a different page address using this command. page address 8 (d 3 ,d 2 ,d 1 ,d 0 = 1,0,0,0) is a ram area that is used exclusively for indicator, so only display data d 0 is valid. 6.3 column address circuit the column address set command specifies the column address in the display data ram, as is shown in figure 6 ? 2. the specified column address is incremented each time a display data read or write command is input, so the mpu is able to successively access display data. incrementation of the column address stops at 83h. the column address and page address are mutually independent, which means that to switch from column 83h on page 0 to column 00h on page 1, both the page address and column address must be separately specified again. also, as is shown in table 6 ? 1, the adc command (segment driver direction select command) can be used to invert the correspondence between the display data ram ? s column address and segment output. this reduces the number of ic layout constraints that are imposed when setting up the lcd module. table 6 ? ? ? ? 1. relation between display data ram column address and segment output seg output seg 0 seg 131 adc ? 0 ? 00h column address 83h (d 0 ) ? 1 ? 83h column address 00h
data sheet s13368ej4v0ds 17 pd16682 6.4 line address circuit as is shown in figure 6 ? 2, the line address circuit specifies the line address that corresponds to a com output for displaying the contents of display data ram. the display start line address set command usually specifies the highest line in the display (corresponding to the com 0 output when in normal mode or the com 63 output when in inverted mode). thus, there are 65 lines in the direction of incrementation of line address starting from the specified display start line address. the screen can be scrolled by dynamically changing the line address via the display start line address set command. figure 6 ? ? ? ? 2. specification of display start line address in display data ram line com d 3 d 2 d 1 d 0 address output d 0 00h com 0 d 1 01h com 1 d 2 02h com 2 0000d 3 03h com 3 d 4 04h com 4 d 5 05h com 5 d 6 06h com 6 d 7 07h com 7 d 0 08h com 8 d 1 09h com 9 d 2 0ah com 10 0001d 3 page1 d 4 0ch com 12 d 5 0dh com 13 d 6 0eh com 14 d 7 0fh com 15 d 0 10h com 16 d 1 11h com 17 d 2 12h com 18 0 0 1 0 d 3 d 4 14h com 20 d 5 15h com 21 d 6 16h com 22 d 7 17h com 23 d 0 18h com 24 d 1 19h com 25 d 2 1ah com 26 0011d 3 d 4 1ch com 28 d 5 1dh start com 29 d 6 1eh com 30 d 7 1fh com 31 d 0 20h com 32 d 1 21h com 33 d 2 22h com 34 0100d 3 d 4 24h com 36 d 5 25h com 37 d 6 26h com 38 d 7 27h com 39 d 0 28h com 40 d 1 29h com 41 d 2 2ah com 42 0101d 3 d 4 2ch com 44 d 5 2dh com 45 d 6 2eh com 46 d 7 2fh com 47 d 0 30h com 48 d 1 31h com 49 d 2 32h com 50 0 1 1 0 d 3 d 4 34h com 52 d 5 35h com 53 d 6 36h com 54 d 7 37h com 55 d 0 38h com 56 d 1 39h com 57 d 2 3ah com 58 0111d 3 d 4 3ch com 60 d 5 3dh com 61 d 6 3eh com 62 d 7 3fh com 63 1000d 0 coms 00 01 02 03 04 05 06 07 7c 7d 7e 7f 80 81 82 83 0 d 0 83 82 81 80 7f 7e 7d 7c 07 06 05 04 03 02 01 00 1 d 0 seg 0 seg 1 seg 2 seg 3 seg 4 seg 5 seg 6 seg 7 seg 124 seg 125 seg 126 seg 127 seg 128 seg 129 seg 130 seg 131 lcd out page address data column adc address page0 page2 page3 page4 page5 page6 page7 page8 0bh 13h 1bh 23h 2bh 33h 3bh com 11 com 19 com 27 com 35 com 43 com 51 com 59 common output status : normal mode note note coms accesses the 65th line regardless of the display start line address.
data sheet s13368ej4v0ds 18 pd16682 6.5 display data latch circuit the display data latch circuit is used for temporary storage of display data that has been output to the lcd driver circuit from the display data ram. the commands that are used to set normal/inverted display modes, display on/off status, and display all on/off status are commands that control data in this latch so that there is no modification of the data in the display data ram. 7. oscillation circuit this is a cr-type oscillation circuit that generates the display clock. the oscillation circuit is valid only when cls = h. when cls = l, oscillation is stopped and the display clock is input via the cl pin. 8. display timing generator the display timing generator generates timing signals from the display clock to the line address circuit and the display data latch circuit. 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 mpu ? 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 and lcd ? s ac conversion signal (fr) are both generated from the display clock. as is shown in figure 8 ? 1, a drive waveform based on the two-frame ac drive method is generated for the lcd driver circuit. if a multiple set of pd16682 chips is used, the display timing signals (fr, cl, and /dof) for the slave side must be supplied from the master side. operation mode fr cl /dof master (m,/s = h) on-chip oscillation circuit is valid (cls = h) output output output on-chip oscillation circuit is invalid (cls = l) output input output slave (m,/s = l) on-chip oscillation circuit is invalid (cls = h) input input input on-chip oscillation circuit is invalid (cls = l) input input input

data sheet s13368ej4v0ds 27 pd16682 12. commands the pd16682 uses a combination of a0, /rd(e), and /wr(r,/w) to identify data bus signals. command interpretation and execution is performed using internal timing that does not depend on any external clock. the 80 series mpu interface activates commands using low pulse input to the /rd pin during read and activates commands using low pulse input to the /wr pin during write. the 68 series mpu interface sets read mode using high-level input to the r,/w pin and sets write mode using low-level input to the r,/w pin. the command is activated using high pulse input to the e pin. thus, the 68 series mpu interface differs from the 80 series mpu interface in that /rd(e) is at high level during status read and display data read operations, as is shown in the command descriptions and command table. command descriptions using an 80 series mpu interface are shown below. if the serial interface has been selected, data is input sequentially starting from d 7 . 12.1 display on/off this command specifies the display ? s on/off status. a0 e, /rd r,/w, /wr d 7 d 6 d 5 d 4 d 3 d 2 d 1 d 0 setting 0 1 0 10101111 display on 0 display off executing the display all on command while the display is off sets power save (low power) mode. for details, see 12.20 power save (compound command) . when the display is off, output via all driver outputs (segment and common) is at v ss level. 12.2 display start line set this command specifies the address of the display start line in the display data ram, as was shown in figure 6 ? 2. the display area extends from the specified line address in the direction of higher line addresses, and includes the number of lines that corresponds to the display duty setting. the display can be smoothly scrolled vertically by using this command to dynamically modify the specified line addresses. for details, see 6.4 line address circuit . a0 e, /rd r,/w, /wr d 7 d 6 d 5 d 4 d 3 d 2 d 1 d 0 line address 0 1 0 01000000 0 000001 1 000010 2 111110 62 111111 63

(1) the oscillation circuit and lcd power supply circuit are stopped. (2) all lcd drive circuits are stopped and both segment and common driver outputs output at the v ss level. 12.20.2 standby mode during this mode, all duty lcd display system operations are stopped and only the static drive system for the indicators operate, which reduces the current consumption to the minimum amount needed for static drive. the internal status during standby mode is as follows. (1) the lcd ? s power supply circuit is stopped. the oscillation circuit operates. (2) the duty drive system ? s lcd drive circuit is stopped and both segment and common driver outputs output at the v ss level. the static drive system operates. when a reset command is executed while in standby mode, it sets sleep mode. remarks 1. if you are using an external power supply, we recommend that you stop the external power supply circuit ? s functions when activating the power save function. for example, if you are using an external divided resistor circuit to provide lcd drive voltage at different levels, we recommend that you add a circuit to cut the current flowing on the divided resistor circuit while the power save function is being activated. 2. the pd16682 includes the /dof pin which is used to control blinking lcd displays is set to low level when activating the power save function. the output from /dof can be used to stop the external power supply circuit's function. 3. when the display has been set to off mode, executing the display all on command sets power save mode no matter which command is entered afterward.

data sheet s13368ej4v0ds 55 pd16682 notes for cmos devices 1 precaution against esd for semiconductors note: strong electric field, when exposed to a mos device, can cause destruction of the gate oxide and ultimately degrade the device operation. 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 v dd 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.
pd16682 m8e 00. 4 the information in this document is current as of july, 2001. the information is subject to change without notice. for actual design-in, refer to the latest publications of nec's data sheets or data books, etc., for the most up-to-date specifications of nec semiconductor products. not all products and/or types are available in every country. please check with an nec sales representative for availability and additional information. no part of this document may be copied or reproduced in any form or by any means without prior written consent of nec. nec assumes no responsibility for any errors that may appear in this document. nec does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from the use of nec semiconductor products listed in this document or any other liability arising from the use of such products. no license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of nec or others. descriptions of circuits, software and other related information in this document are provided for illustrative purposes in semiconductor product operation and application examples. the incorporation of these circuits, software and information in the design of customer's equipment shall be done under the full responsibility of customer. nec assumes no responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and information. while nec endeavours to enhance the quality, reliability and safety of nec semiconductor products, customers agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. to minimize risks of damage to property or injury (including death) to persons arising from defects in nec semiconductor products, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment, and anti-failure features. nec semiconductor products are classified into the following three quality grades: "standard", "special" and "specific". the "specific" quality grade applies only to semiconductor products developed based on a customer-designated "quality assurance program" for a specific application. the recommended applications of a semiconductor product depend on its quality grade, as indicated below. customers must check the quality grade of each semiconductor product before using it in a particular application. "standard": computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "special": transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "specific": aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. the quality grade of nec semiconductor products is "standard" unless otherwise expressly specified in nec's data sheets or data books, etc. if customers wish to use nec semiconductor products in applications not intended by nec, they must contact an nec sales representative in advance to determine nec's willingness to support a given application. (note) (1) "nec" as used in this statement means nec corporation and also includes its majority-owned subsidiaries. (2) "nec semiconductor products" means any semiconductor product developed or manufactured by or for nec (as defined above). ? ? ? ? ? ?
