1. Definition and classification of aerospace and military chips

Military chips refer to professional integrated circuits (ICs) used in national defense and military fields. They are widely used in military computers, navigation, aviation, aerospace, radar, missiles and other fields. According to different functions, they can be specifically divided into sensing chips, communication chips, control chips, power chips, memory chips, etc.

Sensor chips refer to chips that can sense external physical or chemical quantities and convert them into electrical signal output, such as temperature sensors, pressure sensors, photoelectric sensors, etc. Communication chips refer to chips that can realize signal modulation, demodulation, encoding, decoding, amplification, filtering and other functions, such as baseband chips, radio frequency chips, modems, etc. Control chip refers to a chip that can implement functions such as logic operations, data processing, and instruction execution, such as microprocessor (CPU), microcontroller (MCU), digital signal processor (DSP), etc. Power chips refer to chips that can realize power conversion, control and management, such as switching power supply chips, power amplifier chips, driver chips, etc. Memory chips refer to chips that can store, read and write data, such as random access memory (RAM), read-only memory (ROM), flash memory (Flash), etc.

The development of military chips faces many challenges, mainly in the following aspects:

(1) Technical difficulty is high. Military chips are required to have high performance, high reliability, high security, and high anti-interference characteristics, and at the same time, they must adapt to various harsh environmental conditions, such as high temperature, high pressure, high radiation, high humidity, etc. This puts forward extremely high technical requirements and standards for the design, manufacturing, packaging, testing and other aspects of the chip.

(2) The investment cost is high. The research and development cycle of military chips is long, the investment is large, the risks are high, and the return rate is low. Generally speaking, the research and development cycle of a military chip takes 3-5 years, requires tens to hundreds of millions of dollars in investment, and often requires multiple tests and verifications to achieve the desired results. Moreover, since the market demand for military chips is relatively small and the sales price is relatively high, it is difficult to achieve large-scale production and economic benefits. As the basis of various types of electronic equipment, military electronic components benefit from the increase in weapons and equipment brought about by the modernization of the military. With the accelerated installation of new main battle weapons and the updating and upgrading of old equipment, new market space will be brought to the military electronics industry.
