And a processing core as the control of various electronic products, a micro control unit (MCU) is an integrated microprocessor device (CPU), memory (RAM / ROM), a chip counter, and I / O ports. From the MCU core architecture point of view, the microcontroller has experienced years of 8051, based on Arm CortexM core microprocessor, and the last two years popular open source RISC-V microprocessor. Either architecture employed, the use of various manufacturers and digital kernel modules are not much different, but the integrated analog and mixed-signal IC regard to the very different. Allegedly country have a certain scale of SCM vendors have at least more than 30, such as Smart micro. But mostly used with large international companies PIN-PIN compatible design patterns (especially in home appliances and consumer electronics products) only in many applications on price competition to compete for market share.
According ICInsights and The Leading Industry Research Center statistics, in 2018 the global microcontroller market size of about $ 20 billion in sales of about 30 billion, despite steady growth in the next few years, but the average selling price (ASP) continues to decline . In 2018 the scale of China MCU market more than 39 billion yuan, the next 3--5 years microcontroller sales will continue to rise, but mainly concentrated in the low-end 4 and 8-bit microcontrollers, 32-bit high-end products will continue to be the monopoly of traditional semiconductor giant .
Most domestic manufacturers have production MCU 32-bit MCU, apply to different areas of different products, Smart micro-based ARM Cortex-M series kernel development MM32 MCU products have F / L / SPIN / W / P five series, more than 200 models, the cumulative delivery hundred million stars, the highest in the forefront in the local general-purpose 32-bit microcontroller companies. MM32 MCU is widely used in automotive electronics, industrial, electrical, electronics, medical, consumer toys, mobile tablet peripherals, such as display and interaction, every year tens of millions of pieces of equipment the Smart micro MM32 MCU product delivery to the customer.
Mixed-signal SoC market is growing faster than the overall microcontroller is expected from 2019-2023 year compound annual growth rate (CAGR) of 6%, and the average price is higher than the overall microcontroller market. MCU for many local manufacturers, this is a very attractive growth, the key is the need for adequate technical strength and resources to compete for an attractive piece of cake.
From the historical development and future trends in the global semiconductor industry point of view, the semiconductor focus shifted from the US to Japan, then will be transferred to mainland China, after all, this is an inevitable trend. In this major, slow transfer process, there must be heavyweight foundries and chip design company was born and form. Although many local IC design companies in the technology and financial strength are still relatively small, but there will be a smaller number of vendors took to the top of scale and value chain.
