DigiKeyElectronics. MouserElectronics. DigiKeyElectronics: A leading global distributor of electronic components, offering a selection of chip products and an online trading platform. MouserElectronics: provides electronic components and components from all over the worldChip products online procurement platform.
Huaqiang Electronic network: Huaqiang electronic network is a comprehensive website for the procurement of electronic components and raw materials, providing related services for global IC chips, electronic components buyers, suppliers and manufacturers.
Now there are many such websites, such as love procurement, 1688, Mr. IC, you can go to see, the above types are relatively complete, are original products, and there are many models, you can do more comparison, there is a single, very convenient.
Yunhan core city is a well-known one-stop electronic components procurement mall, complete categories are Yunhan core cityAdvantage. New HiBOM with a single tool, batch selection of order saving time and effort.
If you know the model, you can directly use the check chip function, you can see and download all the datasheet parameter data, you can also see the manufacturer, agent and inventory details, if you do not know the model, you can also use screen printing reverse check function, basically you can find.
The Chinese parameter table of the chip is generally available on the official website of the corresponding chipYes. For example, on the common official websites of intel and AMD, you can search for the detailed Chinese parameter table of the chip.
Drag and drop the sensor assembly from the Components library onto your circuit drawing. Connect the pins of the sensor assembly. In general, the pins of the smoke sensor include four pins: VCC positive power supply, GND ground, DO digital output and AO analog output. For details about the connection mode, see datasheet of the sensor.
I have developed an industrial washing machine controller, and the water level sensor relies on the principle of atmospheric powerOutside the input, all internal registers (including control registers) are cleared and all I/O ports are set to input mode. CS: Chip select signal line. When this input pin is low, it indicates that the chip is selected to allow the 8255 to communicate with the CPU.
2, Shilanwei: familiar with Hangzhou Shilan Microelectronics Co., Ltd. people know that the company's core development concept is "integrity, patience, exploration, enthusiasm".
3, Pin 1: PL input pin (low level valid) for asynchronous loading of parallel interface data. When this pin pulls downWhen, the eight cascaded triggers work, loading the state of the external parallel bus D0~D7 into Q0~Q7. When this pin is pulled high, 165 operates in a serial shift mode, shifting at each CP rising edge.
4, here are some examples for you: P4IBMS, the motherboard supports P4 processor, I indicates that the chipset is provided by INTEL, B indicates that the INTEL845 chipset is used. M indicates the board size bit Micro ATX. The last letter indicates that the memory supported is SDRAM.
5, the high performance is due to the fast switch of the component,Lower energy consumption because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm, and one million transistors could be reached per mm.
1, Huaqiang electronic network road Heshun big data chip factory official website Hello, you can Baidu more than three platforms can query the domestic chip factory and chip information.
2, I feel that the core Chacha APP provides the most complete information in this kind of APPAll, the model of the chip and the specific information can be found here.
3, I think the core check is very good, where not only can check the chip, check the model, check the enterprise, etc., but also the mall can purchase, and recently launched the social plate X planet, many people in the electronics industry are using.
1, Looking for chip and datasheet right-hand man? Core check is undoubtedly your first choice! Core Chacha This professional software, with its comprehensive features for electronics engineers and industry enthusiastsFor great convenience.
2, Huaqiang electronic network road Heshun big data chip factory official website Hello, you can Baidu more than three platforms can query the domestic chip factory and chip information.
3, search chip model: use the search engine or Apple official website, enter the chip model to search. View technical specifications: In the search results, find the page related to the chip model, which usually has detailed technical specifications.
4, core check. Recommended core check. You can check the chip, check the exhibition, check the program, check the enterprise, check the patent, find the alternative.
5, I think the core check is very good to use, where not only can check the chip, check the model, check the enterprise, etc., but also the mall can purchase, and recently launched the social plate X planet, many people in the electronics industry are using.
