According to IC Insights survey analysis, the demand for 32-bit microcontrollers (MCUs) in smart car systems will gradually increase in 2013; Gartner pointed out that it is expected that the global output value of automotive semiconductors will reach 25.7 billion US dollars in 2014; The Institute of Industrial Information (MIC) expects to ship 3 billion automotive microcontrollers by 2015.
Michael Anfang, director of the microcontroller and advanced driver assistance systems business unit of the automotive product department of ST, a well-known semiconductor manufacturer, believes that the largest market segment for MCUs is automotive MCUs. It is expected that by 2015, sales of automotive MCUs will account for 32% of the MCU share.
In addition, for the automotive semiconductor market, MCU is also an important part of it. By 2015, automotive microcontrollers will account for 22% of automotive semiconductor revenue.
Since everyone now pays more attention to automobile safety (including hardware safety and software safety), Michael Anfang also predicts that future MCUs for vehicles will take safety performance into consideration, and more and more vehicle MCUs will turn to 32 Bit. The 32-bit MCU has the advantages of higher computing performance, lower power consumption, higher integration, large-capacity storage, and a platform that can integrate information security functions. It will be more and more popular in the automotive market in the future.
Following this trend, STMicroelectronics has launched the SPC5x series of 32-bit MCUs for automotive applications. Michael Anfang said that the SPC5x series is a multi-core MCU for the functional safety of automotive electronic systems.
The SPC5x series of MCUs use the Power Architecture architecture, 192kB internal RAM, 2MB flash memory, 3 CAN interfaces, and peripherals optimized for safety and motor control applications.
Unlike 32-bit MCUs based on ARM and MIPS architectures, SPC5x series MCUs based on Power Architecture architecture have strong scalability (both in performance and architecture); strong compatibility (kernel binary code can Compatible with each other, pin-to-pin compatible with each other); high safety performance, enabling the design to pass SIL3 / ASILD certification (Note: safety standard certification).
SPC5x series MCU products cover everything from low-end to high-end. Some prices are even cheaper than 16-bit MCUs.
The data shows that in 2011, the semiconductor content in China's bicycles was US $ 168, while that in Europe, America and Japan was US $ 350. In comparison, China's auto industry is still lagging behind, especially in the field of automotive electronics, the semiconductor content in bicycles is only developed in Europe, Japan, and other countries Half of the country. However, Michael Anfang said that from 2011 to 2019, China's 32-bit MCU sales are expected to grow at a compound annual growth rate of approximately 16%, and 32-bit automotive MCU sales will grow at a compound annual growth rate of approximately 25%. It can be seen that automobiles are the major 32-bit MCU applications.
