In the context of continued growth in the global semiconductor market in 2014, the global MCU market grew faster. In 2014, the global MCU market sales revenue was 15.67 billion US dollars, a year-on-year increase of 5.5%.
In 2014, China's annual MCU market sales and market sales reached 10.24 billion pieces and 28.23 billion yuan, up 10.8% and 8.5% respectively. The growth of China's MCU market is due to the continued growth of domestic market demand.
32-bit fastest growing SoC is a big trend
With the rise of wearable devices and the Internet of Things, device designs are becoming lighter, thinner, and cheaper. As the spread between 8-bit and 32-bit MCUs has shrunk, the next eight applications will be less and less, plus the 8-bit and 32-bit development platforms, and in the future, the expandable demand for smart home and app applications, Designing with 32-bits may be more cost-competitive. The current growth rate of 32-bit MCUs has far exceeded that of 8-bit and 16-bit MCUs. 32-bit MCUs are growing at a rate of more than 15% globally, with 32-bit MCUs in the ARM architecture growing at twice this rate.
Although MCU and sensor technology have many differences, it is difficult to achieve integration at present, but SoC is a major trend in the industry, especially for some types of sensors that are relatively easy to integrate, such as touch screen controllers, accelerometers, gyroscopes. The integrated chip will have a clear advantage. Domestic and foreign vendors are expanding MCUs to integrate application-specific standard product (ASSP) MCUs or system-on-a-chip (SoC) lineups for front-end (AFE) solutions such as digital converters (ADCs) and operational amplifiers (OPAs) to optimize multiple sensor data. Connect, transform, and compute processes to accelerate the IoT standard operating model from sensing to data conversion and real-time processing.
Internet of Things demand is the biggest driver of growth
The surge in demand in the wearable market has made MCU products with low power consumption and high performance unlimited, and has attracted more and more chip players to actively invest in microcontroller solutions for wearable device requirements. The outbreak of the Internet of Things will become the first driving force for the future growth of MCU products.
Although the 32-bit product mentioned above has the highest growth rate, it has gradually replaced the 8-bit MCU in the market. However, since the 8-bit MCU is simple and easy to use, the power consumption cost is low. As long as the design is proper, the designer can completely use the advanced code space. Language, developed a series of innovative applications. Therefore, in the coming period, 8-bit MCUs can still have a place in various applications such as automobiles, industrial, consumer electronics, and white goods.
With the introduction of China's "Industry 4.0" strategy, the transformation and upgrading of domestic industries is accelerating, and the demand for MCU products in this field will continue to be released rapidly. At present, the main application of MCU in this field is still traditional applications such as industrial motor control. MCUs typically focus on the number of I/O ports and the size of the programmable memory interface, making them ideal for motor systems that require extensive I/O operation and versatility. With the expansion of new motor functions and performance improvements, such as vector control, spatial field orientation, coordinate decomposition, and PI regulation loops, this has often encountered performance bottlenecks in the past with 8/16-bit MCUs. The development of 32-bit high-performance MCU products.
The field of industrial control is a product field with very different needs. It has very high requirements for the customized development and integration capabilities of MCU vendors. This aspect requires MCU vendors to provide more comprehensive MCU series products, and on the other hand, it also promotes MCUs. Vendors offer more comprehensive solutions for integrating front-end chips and back-end processing chips.
Domestic companies are welcoming three advantages
Domestic integrated circuit companies have begun to actively launch MCU products, the main considerations are as follows:
First, a broad market space. As mentioned above, MCU products have a wide range of applications in industrial control, automotive electronics, network communications and many other applications, and the market is huge. If domestic IC companies hope to gain a place in the future semiconductor market, it will be inevitable to enter the MCU market in due course.
Second, the market share is relatively scattered. There is no technology and the market is in an absolute monopoly. It is less difficult for domestic enterprises to enter. Although the top ten companies in the market share are still foreign-funded enterprises, Renesas, which has the largest market share, only accounts for 16.9%. The top ten together account for 80.9% of the overall market. The market competition is relatively full and the share is relatively dispersed. There is no enterprise that is in an absolute position. Domestic companies will face fierce competition when they enter the field, but they will not be suppressed by monopolistic manufacturers.
Third, the requirements of national information security. Due to the wide application of MCU products, many of them involve national information security. Under the country's promotion of information security strategy and the "independent controllability" of integrated circuit products, domestic MCU manufacturers will gain a part of the market near the blue ocean, which will be a great advantage for the domestic autonomous MCU in its infancy.
Fierce competition and clear positioning are key
We have seen many domestic companies actively launch MCU products, such as Zhaoyi Innovation, which focused on memory products before, Huahong IC, which focuses on smart card chips, Shanghai Yiquan, which focuses on energy metering, and a certain foundation in the field of MCU. China Resources Microelectronics and so on. These companies lack a foundation or a weak foundation in the MCU field. When they enter the field actively in response to market trends, they will encounter a series of problems.
First of all, in the field of high-end equipment manufacturing, automotive electronics, network communications, etc., the requirements for MCU products are high. These areas are also the main battlefields for MCU first-line manufacturers to compete. Customers in these fields have strict certification mechanisms for their products, and the established partnerships are relatively stable. With the current technical strength and product performance, domestic manufacturers are unlikely to gain considerable market share in these areas in the short term. In the low-end areas such as consumer electronics, instrumentation, etc., domestic manufacturers will have the strength to compete with international first-tier manufacturers, but may face the pressure of foreign-funded manufacturers in the low-end products sector, the channel expansion capability and capital for domestic enterprises. Strength will be a big test.
Secondly, the mainstream products of the first-line MCU manufacturers are basically based on ARM core development. It is difficult to open a big gap in terms of core parameters. The competition has expanded from the competition of a single MCU core to the application. The wizard's solution to the competition. From the perspective of industrial integration in recent years, the first-line manufacturers in the industry are actively expanding their product lines, including connecting chips and front-end sensor chips, by means of mergers and acquisitions, etc., in order to provide customers with a full set of products. Complete solution. Domestic integrated circuit companies are not only weak in the MCU field, but also have insufficient strength in other fields, and internal industry integration is difficult.
Based on this, it is recommended that when Chinese domestic semiconductor companies enter the MCU market, they should first define the technology and market development trends, determine the technical route and product positioning, and focus on 32-bit products based on the ARM core. Secondly, they must clearly define their own market positioning. In the segmentation field, focus on improving products and solutions for specific segments; in the end, Chinese semiconductor companies should pay more attention to their own channel construction and customer cooperation, relying on their own localization advantages, and gradually form a cooperation with downstream manufacturers. A stable partnership.
