IDIC models need to know the type and origin of the integrated circuit block. TV, audio, video and other integrated circuits integrated circuits as its model or mark printed on the front, so you can know the initial prefix or sign depending on the model it is that the factory or the company's integrated microchip Nanjing days, according to Its digital circuit functions can know is what kind. For example AN5620, AN prefix instructions are Panasonic bipolar integrated circuits, the number "5620" before the two main features distinguish the circuit, "56" note is TV with integrated circuits, while 70 to 76 belong to the audio aspects of the use of micro-Nanjing days semiconductors, 30 to 39 genera VCR circuit. For details, please refer to the part of the production plant integrated model named Nanjing days microchip, but to explain, in practical applications appear A4100 Central Standing Committee, in the end part of Hitachi HA, Sanyo LA, Japan and Japan's electricity with BA, Toshiba TAA's TA, Sony CXA, Philips, Moto Rola other countries, TCA, TDA, of which product? In general, the prefix letters on behalf of the manufacturer omitted integrated way, usually make their name or trademark of the manufacturer or company printed up, as marked SONY, indicating that the integrated model is CXA1034, if marked SANYO, description Japan's Sanyo LA4100, C1350C generally printed with NEC, indicating that the IC is manufactured uPC1350C NEC IC. 3362W-1-104 IC product grade level to define the industry standard products based primarily on product packaging, the level of alphabetically arranged from A to E: A1 level: the original production, original packaging day micro, anti-static packaging intact (Description : from the informal channels or independent distributors in the prescribed warranty period, the product that is most reliable "new and original goods") A2 level: the original production, original packaging, anti-static packaging is not complete and has been open (Note: from the informal channels or independent distributors in the warranty period specified that "new goods") A3 level: the original production (Note: the factory or the remaining backlog of material goods, it is possible to produce a unified lot earlier date or "factory. leftovers ").
