1, improve English reading level: In terms of reading the chip data manual, improve English reading ability is very important. You can try to improve your reading ability by reading simple English articles, taking English learning courses, etc.
2, if the English is not very good friends, it is recommended to try to find the Chinese datasheet, or the English is not very good, it is also recommended to find the Chinese version after reading, and then look at the English version, or a combination.
3, carefully study the manual when givenSequence diagram, which is the key to the correct operation of the chip. The period of the individual signal, the rise time, the fall time, the build time, the hold time, and the phase relationship between the signals must all be studied thoroughly.
4, first of all, open the Baidu search engine in the browser, and search the chip data manual query, click the first result in the search results to enter. Then, enter the chip model in the search box on the home page of the open China Electronics Components network, and click the search button.
5. The whole device must be erased quickly. Execution s of the Chip-Erase operationixbyte The sequence of commands that initiate the software's data protection Chip-Erase command (10H) address 555H in the past byte sequence. The internal deletion operation begins on the sixth rise along our # or CE #, whichever is first.
6, the manual of KSZ8081 writes: Strap-In can be considered as "the default configuration process after the chip is powered on/reset", Strap-In enables the PHY chip to enter the expected working state after the power-on/reset, such as the PHY address of the chip, transmission line rate, and whether the rate is automaticThe chip should operate at a power consumption less than this value.
2, sleep current is static current. Static current refers to the current when there is no signal input, that is, the device itself consumes current without being affected by external factors. It is described in the data manual of many chips, and this value can calculate the static power consumption of the chip itself.
3, OC gate output high voltage usually is a high resistance state, the pull-up current to be provided by the pull-up resistor, the input port is not more than 100uA, the output drive current is about 500uA, the standard operating voltage is 5V, the input port of high and low powerThe flat threshold is 0. 8V (below this value is low level); 2V (high level threshold).
4, uA x 4K= 2 that is, when the output is greater than 4K, it can be pulled down to below 0.8V, which is the minimum resistance value, and then it can not be pulled down. If the output drive current is large, the resistance value can be reduced to ensure that it can be lower than 0.8V when pulled down.
5, manually enter the CPU external frequency value you want to set, which allows the input value range between 100-200, you can increase the frequency of every 1MHz for linear overclocking, to maximize the potential of the CPU.
6, the human eyes and their data transmission system can recognize 10-12 frames per second, and the brain's visual processing center will retain each frame for 1/15 second. If the brain receives a new picture within 1/15 seconds of the previous picture being retained, it creates the sense of continuous motion of the picture, which is the cognitive basis for the realization of the film.
Can not find the device manufacturer's official website to look for. Find the official website and search the corresponding version in the search barYes. Realtek 8201 this PHY chip has many different suffixes representing different version numbers, so you should see the version when you go to the official website.
Search the chip data book on Baidu and open the first chip search website. Enter the chip model you want to query in the search box. Check the model, manufacturer, description, and whether it is the chip you want to query.
First of all, open the Baidu search engine in the browser, and search the chip data manual query, click the first result in the search results to enter. Then, enter in the search box of the home page of China Electronics Device networkChip model and click the search button.
First, you can try to find the triode data book through a search engine. Enter the keywords "triode data manual" or "triode parameter manual" and other related words, it is likely to get some commonly used data manual website links. Some sites may offer free downloads, while others require registration or purchase.
See the data manual has some skills, mainly 1, if the English is not very good friends, it is recommended to try to find the Chinese datasheet to see, or the English is not very good, it is also recommended to find the Chinese version firstAfter reading the original, then read the English version, or a combination of them.
1. On the website https://easydatasheet.cn, click "Translate Now" below the search box:.
2, I have been on a website called search ic data manual, the chip data inside are Chinese, it seems to be achieved with this automatic conversion translation technology.
3, the Chinese parameter table of the chip is generally in the official website of the corresponding chipYou can find it on. For example, on the common official websites of intel and AMD, you can search for the detailed Chinese parameter table of the chip.
4, Solution one: find ST FAE. If you use enough, FAE will do everything for you. Solution 2: Search the Chinese version of the material on the domestic website, if someone is obliged to translate... Be on the lookout for translation errors (although the st documentation itself is full of errors). Solution 3: Put your hope in an automatic translation engine.
5, intel Chinese data manual download on the official website. You can go to the Intel website, the home pageSearch "Installation Manual for boxed desktop Processors" to find the instructions for downloading.
Focus on the parameters of the chip, and you can refer to some parameter diagrams given in the manual (such as TPC1, TPC2, etc.), which is an important basis for whether to use the chip.
See the chip manual programming mainly to see some important parameters and control timing of the chip.
Search for the chip data book on Baidu and open the first oneChip search website. Enter the chip model you want to query in the search box. Check the model, manufacturer, description, and whether it is the chip you want to query.
First of all, open the Baidu search engine in the browser, and search the chip data manual query, click the first result in the search results to enter. Then, enter the chip model in the search box on the home page of the open China Electronics Components network, and click the search button.
