Ziguang Guowei: domestic chip leader.

Tianjin Zhonghuan Semiconductor Co., Ltd. was founded in 1999, formerly known as Tianjin No. 3 Semiconductor Device Factory established in 1969, completed joint-stock transformation in 2004, and was listed on the Shenzhen Stock Exchange in April 2007. The stock is referred to as "Zhonghuan Stock", the code is 002129. It is a high-tech enterprise producing and operating semiconductor materials and semiconductor integrated circuits and devices, with a registered capital of 482,829,608 yuan and total assets of 205.1 billion yuan.

cE certified eMI radiation is read his QP value?

The "CE" mark is a safety certification mark that is regarded as a passport for manufacturers to open and enter the European market. CE stands for CONFORMITE EUROPEENNE (European Unity). All products with the "CE" mark can be sold in the EU member states, without meeting the requirements of each member state, so as to achieve the free circulation of goods within the EU member States.

Usually only EMC and safetyBoth parts, wireless products need to increase the wireless part of the test or SAR part of the test depending on the specific situation. CE is the abbreviation for compulsory certification of various products in continental Europe, and now the more mature certification business can be carried out after confirming the information of price, cycle and sample, and it is necessary to pay attention to the qualification situation of the final report.

CE certification is a compulsory certification of the European Union, CE is short for "European Community European Conformity" in French, CE certification it is a safety mark, whether it is produced by EU member States or other non-member products must be addedHow to solve the problem of charging Internet of Things (IoT) devices

So many wireless sensors must be able to power themselves. Harvesting energy from the surrounding environment has become the preferred solution for wireless charging EMI analysis Wireless charging EMI analysis , Or extend the interval between battery replacement by increasing the capacity of rechargeable storage devices Wireless charging EMI analysis , even without replacing the battery. The variety of energy sources currently available Wireless charging EMI analysis , which includes solar, thermal and vibration energy, and even the use of the surrounding radio frequency (RF) power supply.

[Rice charging joint is covered by oxide] The surface of the metal charging joint of the rice is easy to be oxidized, and the oxide covers the metal joint, resulting in no charging. Take a small blade and gently scrape the metal joint, and then try to charge it. (3) [bracelet charging cable failure] This is a hardware failure, the detection method is to borrow the charging cable of friends around to try, if you can charge it, it shows that there is a problem with your charging line.

While batteries are sometimes the bane of mobile devices and sensors, this power source is not reliable and must be recharged or replaced regularly, which may become the biggest weakness of the Internet of Things (IoT).

Huawei HiLink solves these problems through the "three-piece set" of HiLink open platform, LiteOS end-side intelligent system and IoT dedicated chip. The HiLink platform has connected more than 30 million users and 600 ecological partners, covering more than 100 categories, providing one-stop development tools for developers and reducing the difficulty of hardware adaptation.

In the new era of Internet of ThingsWith the rapid development of the Internet of Things (IoT), ultra-micro, low-power sensors and devices have become an invisible pillar of People's Daily life. However, the challenge of continuously powering countless devices looms large, with the size and weight of conventional batteries limiting their portability and sustainability. Tribopower generation technology came into being, providing a lifeline to this problem.

soc(System-level Chip) Details

SoC is System on Chip abbreviation, literal translation is "chip level system", often referred to as "system on chip". Because it involves "Chip", SoC will also reflect the connection and difference between "integrated circuit" and "chip", and its related content includes integrated circuit design, system integration, chip design, production, packaging, testing, and so on.

The current development of microelectronics technology has entered the era of system-integrated Chip (SOC-System On Chip). The entire system or subsystem can be integrated on a single silicon chip. Further development, can be a variety of physical, chemicalThe sensor (performing information acquisition function) and the actuator are integrated with the information processing system to complete the system function from information acquisition, processing, storage, transmission to execution, which is a system integration chip in a broader sense.

AtomS1200 currently includes three products, relying on 22nm advanced manufacturing process, the lowest power consumption TDP is only 6W, the whole series has 64bit architecture, virtualization, support up to 8GBDDR3 memory (support ECC debugging) and 8 groups of PCIe0 channels, for system-level single chip (SoC) products, Reducible boardDesigned and provided with low power consumption, low heating characteristics.

Integrated circuit technology is through a series of specific processing technology, the transistor, diode and other active devices and resistors, capacitors and other passive devices, in accordance with the fixed circuit interconnection, integrated on a semiconductor single chip, to perform a specific circuit or system function. A distinctive feature of the current development of microelectronics technology is the emergence of the concept of System On Chip (SOC).

Such ASics are often referred to as SoC (System on Chip). FPGAIs a close relative of ASIC, generally through the schematic, VHDL digital system modeling, the use of EDA software simulation, synthesis, generation based on some standard library network table, configuration to the chip can be used. The difference between it and ASIC is that the user does not need to intervene in the layout and process of the chip, and can change its logic function at any time, and the use of flexible.

What does soc mean?

1. SOC, or SoC, is an abbreviation that includes: SoC: short for System on ChipIt is also called system-on-chip, meaning that it is a product, is an integrated circuit with a special goal, which contains the complete system and has all the contents of the embedded software. SOC: Security Operations Center, a security operations center in the field of information security.

2, EN indicates the European standard, SOC indicates the state of charge, that is, the remaining power. soc indicates the remaining battery capacity. The value ranges from 0 to 1. If SOC=0, the battery is completely discharged. If SOC=1, the battery is completely dischargedFull. After the vehicle battery is used for a period of time, it is necessary to use the battery detector to detect the use of the battery, and it does not meet the needs of timely replacement.

3, generally speaking, SoC is called system-level chip, also known as system-on-chip. It means that it is a product, an integrated circuit with a specific purpose, which contains the complete system and has all the contents of the embedded software. At the same time, it is a technology to realize the whole process from determining the system function, to software/hardware partition, and complete the design. Definitions of SoC vary.
