SDA SCL START condition STOP condition Figure10. 2-SPI Command/Data transfer Format It has to generate the condition such as START condition and STOP condition in 2wire serial interface transfer method. Slave address S 0 1 1 1 1 1 0 0 A C A Command Display Data A P 0 Command or data judgment bit START condition STOP condition Acknowledge Figure11. Interface protcol Method of how to transfer command and data is shown as follows. 1) Generate “START condition”. 2) Issue Slave address. 3) Transfer command and display data. ○Acknowledge Data format is 8bits and return Acknowledge after transfer 8bits data. When SCL 8th=’L’ after transfer 8bit data (Slave Address, Command, Display Data), output ’L’ and open SDA line. When SCL 9th=’L’, stop output function. (As Output format is NMOS-Open-Drain, can’t output ‘H’ level.) If no need Acknowledge function, please input ‘L’ level from SCL 8th=’L’ to SCL 9th=’L’.

MSB (“command or data judge bit”) of command decide to next data is command or display data. When set “command or data judge bit”=‘1’, next byte will be command. When set “command or data judge bit”=‘0’, next byte data is display data. S Slave address A 1 Command A 1 Command A 1 Command A Display Data A 0 Command … P Once it becomes display data transfer condition, it cannot input command. When want to input command again, please generate “START condition” once. If “START condition” or “STOP condition” are inputted in the middle of command transmission, command will be canceled. If Slave address is continuously inputted following “START condition”, it will be in command input condition. Please input “Slave Address” in the first data transmission after “START condition”. When Slave Address cannot be recognized in the first data transmission, Acknowledge does not return and next transmission will be invalid. When data transmission is in invalid status, if “START conditions” are transmitted again, it will return to valid status. Please consider the MPU interface characteristic such as Input rise time and Setup/Hold time when transferring command and data (Refer to MPU Interface). ○Write display and transfer method This device has Display Data RAM (DDRAM) of 20×4=80bit. The relationship between data input and display data, DDRAM data and address are as follows; Slave address Command S 01111100 A 0 0000000 A a b c d e f g h A i j k l m n o p A … P Display Data 8 bit data will be stored in DDRAM. The address to be written is the address specified by ADSET command, and the address is automatically incremented in every 4bit data. Data can be continuously written in DDRAM by transmitting Data continuously. (When RAM data is written successively after writing RAM data to 13h (SEG19), the address is returned to 00h (SEG0) by the auto-increment function.

If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc. (2) Operating conditions These conditions represent a range within which characteristics can be provided approximately as expected. The electrical characteristics are guaranteed under the conditions of each parameter. (3) Reverse connection of power supply connector The reverse connection of power supply connector can break down ICs. Take protective measures against the breakdown due to the reverse connection, such as mounting an external diode between the power supply and the IC’s power supply terminal. (4) Power supply line Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines. In this regard, or the digital block power supply and the analog block power supply, even though these power supplies has the same level of potential, separate the power supply pattern for the digital block from that for the analog block, thus suppressing the diffraction of digital noises to the analog block power supply resulting from impedance common to the wiring patterns. For the GND line, give consideration to design the patterns in a similar manner. Furthermore, for all power supply terminals to ICs, mount a capacitor between the power supply and the GND terminal. At the same time, in order to use an electrolytic capacitor, thoroughly check to be sure the characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant. (5) GND voltage Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric transient. (6) Short circuit between terminals and erroneous mounting In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or between the terminal and the power supply or the GND terminal, the ICs can break down. (7) Operation in strong electromagnetic field Be noted that using ICs in the strong electromagnetic field can malfunction them. (8) Inspection with set PCB On the inspection with the set PCB, if a capacitor is connected to a low-impedance IC terminal, the IC can suffer stress. Therefore, be sure to discharge from the set PCB by each process. Furthermore, in order to mount or dismount the set PCB to/from the jig for the inspection process, be sure to turn OFF the power supply and then mount the set PCB to the jig. After the completion of the inspection, be sure to turn OFF the power supply and then dismount it from the jig. In addition, for protection against static electricity, establish a ground for the assembly process and pay thorough attention to the transportation and the storage of the set PCB. (9) Input terminals In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input terminal. Therefore, pay thorough attention not to handle the input terminals, such as to apply to the input terminals a voltage lower than the GND respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input terminals when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input terminals a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics. (10) Ground wiring pattern If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay attention not to cause fluctuations in the GND wiring pattern of external parts as well. (11) External capacitor In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc. (12) No Connecting input terminals In terms of extremely high impedance of CMOS gate, to open the input terminals causes unstable state. And unstable state brings the inside gate voltage of p-channel or n-channel transistor into active. As a result, battery current may increase. And unstable state can also causes unexpected operation of IC. So unless otherwise specified, input terminals not being used should be connected to the power supply or GND line. (13) Rush current When power is first supplied to the CMOS IC, it is possible that the internal logic may be unstable and rush current may flow instantaneously. Therefore, give special condition to power coupling capacitance, power wiring, width of GND wiring, and routing of connections. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.
