As is well known in the industry, the development history of motor has been more than one hundred years, and it has become a major energy consumer. With the year-on-year increase in energy efficiency requirements and the continuous demand for motor noise reduction, improving efficiency has become the theme of continuous improvement in the motor industry.
Under this background, BLDC brushless DC motor has gradually replaced AC induction motor with its advantages of small size, low noise, high efficiency and long life, and has been widely used in household appliances, industry, automobile and other fields. According to the agency‘s prediction, the market size of BLDC motor is expected to reach 19.76 billion US dollars in 2022.
Jin Zhao said: "smart microelectronics mm32spin Series MCU products are tailor-made for DC brushless motor drive. At present, the series of motor products have 10 packaging forms and nearly 50 models for customers to choose from, which can meet the needs of many motor applications in the market, such as electric tools, hand-held vacuum cleaners, electric bicycles, robot actuators, range hoods, fans, micro low-voltage fans and so on."

Insiders pointed out that if the motor wants to achieve high speed, the main frequency speed and driving accuracy must reach a certain height. It is difficult to do it with ordinary MCU. Therefore, most manufacturers will put some hardware IP specially designed for the motor, as well as peripheral devices such as comparators, operational amplifiers and ADCs in the chip to improve the speed and sampling accuracy of the motor.
"Mm32spin series adopts arm Cortex-M0 / m3 core, provides up to 512KB flash memory space, and has built-in multi-channel UART, I2C, SPI, can and other communication modules, as well as a variety of high-precision analog peripherals such as comparators, 12 bit 3msps ADCs and operational amplifiers. Among them, the driving MCU provides the function of integrated power supply, abundant peripherals such as pre drive, LDO and MOSFET. The voltage range is 20V, 60V, 200V and 600V. The products are rich and can be rooted Professional customization according to user needs. " Jin Zhao said.
Take the mm32spin580c motor MCU product as an example, which uses the high-performance arm? Cortex?- M0 is the core, with a maximum operating frequency of 96mhz, built-in operational amplifier, comparator, rich I / O ports and communication peripherals. Mm32spin580c can provide customers with a highly integrated solution suitable for three-phase motor control.
As for the innovation of this product, Jin Zhao pointed out: "high integration, high reliability and small package are the biggest characteristics of mm32spin580c. Since the launch of this product, it has been widely praised by the market and recognized by many customers. Customers cover the fields of garden tools, server fans, vacuum cleaners, electric two wheeled vehicles, balance vehicles and so on.
Diversified layout offsets the impact brought by the decline in consumption and takes the opportunity to actively expand to high-end fields
Because MCU can provide different combination control for different application scenarios, MCU can be seen in many fields such as mobile phone, PC, automotive electronics and industry. In recent years, driven by many downstream demands, MCU has developed rapidly. According to IC insights, the global MCU market sales will increase by 10% in 2022, and the market scale is expected to reach US $21.5 billion, a new record. In the next five years, the sales of 32-bit MCU is expected to grow at a compound annual growth rate of 9.4% and reach US $28.5 billion by 2026.
From the perspective of the global MCU pattern, the industry concentration is relatively high, and the market share of foreign giants such as Renesas, NXP, Infineon and microchip exceeds 80%. Although domestic manufacturers are blooming, they are still catch ing up.
In terms of application fields, there is a big difference in the application distribution between the Chinese MCU market and the global MCU market. From the application field, the global MCU market application is mainly concentrated in the middle and high-end fields such as the automobile and industrial market, accounting for 60%; While China is mainly concentrated in the middle and low-end consumer market, accounting for 26%, and the total of automobile and industry is less than 30%.

Affected by repeated epidemics, high inflation and geographical conflicts, the global economic recovery is weakening. People‘s demand for consumer electronics such as smart phones, PCs and tablets is weakening, and the pressure of shipment and order cutting is coming. The price of MCU, which was relatively hard and in short supply, has begun to loosen.
Jin Zhao said: "This year, domestic MCU will face severe challenges, especially the individual companies with irrational price increases last year. This year, they will face great pressure from channels and customers. Of course, this does not mean that domestic MCU manufacturers have lost opportunities. On the contrary, after this wave of adjustment, some manufacturers with serious low-end homogeneous competition will be gradually eliminated, and some powerful manufacturers will seize this share against the trend and take the opportunity to expand into the high-end field."
It is worth noting that although the current demand for consumer MCU is slowing down, the demand for automobile and industrial control MCU is still very strong. Especially in the field of automobile MCU, the demand is still in short supply.
For the current market of MCU structural differentiation, Jin Zhao pointed out: "The layout of smart micro products is diversified, so the weakness of the consumer side can basically be offset by the growth of products in other fields. In the new energy vehicle market, due to the long verification cycle and the large increase in the number of MCUs required for the development of intelligence, the automotive sector will be a relatively certain opportunity point in the next 3-5 years. In addition, due to the needs of the digital transformation of traditional industries, the industrial control sector will also be a relatively large one A steadily growing market. "
epilogue
In the aiot era, all electronic products will be upgraded intelligently, including more intelligent human-computer interaction, processing, networking and AI functions, which require MCU with higher performance, higher quality and lower power consumption. It can be said that MCU is one of the basic devices of the next generation of super Internet and will usher in a better development prospect.
As the representative of ecological products, the improvement of MCU enterprises depends on the construction and perfection of its ecosystem to a large extent. Smart microelectronics has been deeply engaged in MCU for more than ten years. It has launched more than 200 models of mm32 MCU 4 series for 8 application scenarios such as automobile, industrial control, white goods and medical treatment. Its MCU ecological construction has been in a leading position in China. After the test of the market, we believe that smart microelectronics has the ability to stand out from many MCU enterprises, and then drive into the fast lane of development.
