We prepare various data and tools for every development STEP as follows other than this technical note, please contact the sales staff in your duty also including the support system. (1) Demonstration STEP (You can try the standard image processing functions by the standard Demonstration kit at once.) You can confirm on TV screen what carried out AIE processing of a camera image and the DVD video image. ・Standard Demonstration board kit ◎Demonstration board(TV-IN→BU1573KV→TV-OUT board) ◎Demonstration board operation manual ◎Demonstration software If the software for the trial board is installed in your Windows PC(Windows 2000/XP), more detailed setting is possible. ◎USB cable (2) Confirmation STEP (We will respond to customer’s camera module.) ・Specifications We will provide specifications for AIE Adaptive Image Enhancer according to customer’s requirements. ・Function explanation We will deliver you the function explanation describing detailed functions, register settings, external interfaces, timing, and so forth of AIE Adaptive Image Enhancer according to your requests. ・Application note We will deliver you the detailed explanation data on application development of AIE Adaptive Image Enhancer according to your requests. (3) System check STEP (You can check the application operation as a system by the kit of system check tools and your camera module.) You can check the interface with your camera module and the application operation on the system check board using the tools for user’s only. ・System check tools kit ◎Board for system evaluation ◎Manual for system evaluation ◎Macro command file for reference *You can check the detailed functions of the application operation by your PC using the macro command file. (4) Integrated check STEP with user’s system (You can check the application operation as a system on your system check board using the integrated check software.) You can check the application operation on the sample LSI-equipped system check board by your camera module using the integrated check software. ・On line Support；We will answer your questions about the software development. ●Cautions on use (1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. 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, for 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. www.rohm.com © 2009 ROHM Co., Ltd.

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. ●Order Model Name Selection B U 1 ROHM model name 5 7 2 Product number ●Tape and Reel information E G U W 2 Package type Taping model name GUW: VBGA063W050 KV: VQFP64 KU: UQFP64 E2: Embossed reel tape None: Tray VBGA063W050 <Tape and Reel information> <Dimension> Tape Embossed carrier tape (With dry pack) Quantity 2500pcs Direction of feed E2 (The direction is the 1pin of product is at the upper left when you hold reel on the left hand and you pull out the tape on the right hand.) 1234 1234 Reel (Unit:mm) www.rohm.com © 2009 ROHM Co., Ltd.
