The following list of chips, called Wang Zhongwang in the chip best. Of course, due to the limitations of the author's level and vision, the list is for reference only, but the price is basically reliable!

1, XQR5VFX130-1CF1752V


Package: BGA

Uses: Aerospace grade / radiation resistant

Dimensions: bare mm price: "1.2 million

Note: The original price is 30,000-30,000 US dollars, and the supplier has a price of 4 million yuan, but it is said that there is no way to supply.

2, XQR4VSX55-10CF1140V


Package: CLCC

Uses: Aerospace grade / radiation resistant

Price: "500,000

Explanation: The original price is about 25,000 US dollars. The current market price has basically turned around 3-10 times. Some people are willing to pay more than 1.3 million, which shows the high value of the chip.

3, XQR2V6000-4CF1144H


Package: BGA

Type: Aerospace class / radiation resistant

Price: "800,000

Note: The original price is 20,000-30,000 US dollars, and the Chinese channel market price is about 1 million yuan. It is said that China has only one orphan.

Description: The original price is around 20,000 US dollars, and the market price is 60-80,000 US dollars.

Why is it so expensive?

For chips in outer space and space applications, in addition to high-speed computing capabilities, they must also have special properties such as radiation resistance. Because the space environment is extremely complex, a large amount of space particle radiation can cause degradation or even functional failure of the on-board circuit, causing a fatal blow to the satellite. Therefore, the difficulty of radiation resistance has all been transferred to the chip design, and the anti-radiation chip design is a worldwide problem. In addition, in addition to the high performance of the chip high-speed computing, storage, logic capabilities, collaborative processing, etc., severalspecial requirement:

1, flatness,At present, the flatness of the chip is far from the requirements of aerospace, so it requires special high-precision equipment and production packaging level.

2, reinforcement,Aerospace-class chips must undergo special reinforcement measures to maintain their use in space. Otherwise, once they are on the star, they will be affected by radiation and particles, and failure will cause them to fail.

3, heat dissipation, reliability, high temperature resistance,When the circuit is applied on the ground, the release of heat mainly depends on heat radiation and heat conduction; in the vacuum state of space, the heat conduction efficiency is extremely low, and the heat generated by the operation of the chip should be released as soon as possible.

Global puzzle

The long period of research and use of aerospace models determines the slow update of component products, which may cause backward technology. Even if the price of high-reliability components is 10 times that of the same commercial product, it will not be able to make up for the backwardness of technology and the decline in market share caused by slow product replacement. Comprehensive assessment, the military and aerospace high-reliability components market has gradually lost the impact on the component market.

In this context, US component suppliers have become increasingly reluctant to support a market that requires separate production lines, complex inspection and testing procedures, and relatively high management costs and low economics. More and more traditional suppliers of high-reliability components have gradually withdrawn from the lower-profit military and aerospace markets. Since 1992, at least 12 large component suppliers, including Freescale and Intel, have withdrawn from the military market.

US space budget

In the United States, 14% of the aerospace component project special funds are used to improve FPGAs (field programmable gate arrays), 12% for improved memory and 8% for advanced mixed-signal circuits. These are the problems in the world-class puzzle of the chip, and also the top card in the top card of the sky-high price chip. In Europe and Japan, there are also heavy funds invested in special funds for aerospace components.

Are the faults of the control

These national treasure chips are also the technical crystallization of US and European technology workers. Therefore, Americans have stricter control over the channels of these chips than population control. China is one of the countries under control and a competitor to the United States. It is a miracle that the chips that were not expensive in the United States could be shipped to China. As for the price, it is not a problem.
