Why choose a 32-bit microcontroller? The mainstream 32-bit single-chip microcomputer is basically occupied by the ARM platform, because the development is convenient and the tools are complete. With the upgrade of major microcontroller manufacturers such as Atmel/Microchip. The ARM-licensed single-chip microcomputers are all over the world, and manufacturers who basically do digital are doing related chips. ARM has more advantages in command density and so on, while traditional MCU manufacturers require chips to be targeted, without copyright fees, and at relatively low cost. The power consumption of all kinds of single-chip microcomputers is basically the same, mainly based on application--the power consumption is not the problem of the single-chip microcomputer, but the original factory and the process. In the application program, 32-bit MCU mainly reflects its high performance and rich resources. At the same time, the convenient development environment attracts more and more software engineers. Therefore, the development difficulty is also the main reason for the rapid rise of 32-bit MCU. one. 32-bit microcontroller, what is the engineer's most concerned about? 32-bit single-chip microcomputer due to its breakthrough in performance, so its selection, that is, the selection of its peripherals, select different types of microcontroller for different systems, usually due to resources and other issues entangled in the selection, from some engineers Personal selection experience, generally choose a general-purpose chip, which is easy to purchase, and the supply is stable, but the general-purpose chip is not suitable for special occasions, which is the most troublesome thing to choose. In this case, the technical indicators mentioned above are not very critical parameters in the selection, small batch procurement cost / procurement difficulty / development environment establishment / open resources and whether it is easy to be cracked becomes a more important problem . In a 32-bit system, whether development is easy or not is a very critical issue. Because it is measured, the cost is not a problem. Because the last system is to win on the software. Is Coreco more competitive than Renesas Electronics? For Silicon Labs' Precision32 series and Renesas Electronics V850 series 32-bit microcontrollers, although the two 32-bit microcontroller manufacturers use the Cortex-M3 core, the main functions are still different because the vendors meet different customer groups. What is the difference between the functions of a series of 32-bit microcontrollers? What are the main application areas of Silicon Labs' Precision32 series microcontrollers? What about the Renesas Electronics V850 series? In fact, the difference between this question is difficult to answer in this comparison. It can be said that in terms of specificity, Silabs pays more attention to market segmentation, and from the perspective of coverage, the V850 covers a wide range of industry applications. Silabs' mcu inherits the American market segment and is more competitive (cost advantage) in this segment than the V850, and the V850's comprehensive coverage allows it to meet most applications. Intel and ARM, who will take the lead? Intel and ARM, respectively, represent the high-performance and low-power of the MCU industry. From the perspective of product development and design solutions, from the perspective of embedded, especially in the rapid rise of smartphones and mobile Internet, ARM is occupying the boss. Status, while moving Intel's cheese through the embedded. Intel's high R&D investment and maintenance of its production line are destined to be unable to compete with low-cost 32-chip and ARM. ARM's flexible, low-cost operation and its low-power experience make it easier to preempt in the embedded market. First opportunity. Therefore, 32-bit single-chip microcomputers are bound to completely replace the 8-bit and 16-bit microcontroller markets. This is the same trend that dos is quickly replaced by windows. The speed of development is far more important than cost. In addition, according to the interaction with engineers or industry experts, currently in the design project, the ARM9 series 32-bit microcontroller is the mainstream. Because the performance price ratio is better. It is more likely to turn to the A8 series later. Factors restricting the development of 32-bit microcontroller market In fact, it is software that restricts the rapid development of single-chip microcomputers. The focus of Hi-tech's acquisition by michrochip is here. How to do more things under the same resources through software, this is the battlefield of everyone's shopping in the future. The semiconductor factory needs to be deeply integrated with the software in order to obtain long-term profits and markets, otherwise it will become a haste. Future 32-bit microcontroller market and technology highlights The future market will be the world of market segments. Customization may not be advantageous because the time period is too long. Future MCUs will occupy a very favorable position in the market segment. In fact, a system, MCU is not the core, its selling point is different peripherals, which is the key to personalization. Because of the information asymmetry, the cost of the information industry is relatively transparent, the price of IT products is falling every day, and the price of the fashion industry is rising every day. Therefore, the MCU must not be the core of competition at the end, and the core is the peripherals supporting the MCU. Therefore, those peripherals and vendors' ability to integrate these peripherals are the highlights we need to focus on in the future. Emerging technology markets such as the Internet of Things and smart grid are brewing out. The 32-bit single-chip set performance and development are convenient, and it is bound to completely replace the old system in the future market, and gradually occupy the market segments separately. From this point of view, the application prospects of 32-bit single-chip microcomputers should be bright. 32-bit microcontroller is irreplaceable in automotive electronics applications In fact, the automotive electronic master control system is basically a 32-bit system. The 32-bit machine in the automotive electronics application as an auxiliary subsystem can indeed bring a lot of convenience to customers in various occasions, such as the driving safety and body stability mentioned above. The intelligent driving system must have a 32-bit system combined with high-speed DSP. Otherwise, it is difficult to cope with complicated road conditions. This kind of subsystem is necessary to prevent the driver from being trapped in a high-speed driver because of fatigue. Subsystem. In the city, the reversing assist system is also a very important subsystem, so that the majority of novices who do not reverse the car have more convenient parking means. For the time being, the largest application area for 32-bit microcontrollers is communication networks, followed by industrial control, automotive electronics, Internet of Things, and medical electronics. Among them, below $1, 32-bit microcontrollers with flash and ram will pose a threat to 8-bit/16-bit microcontrollers. At present, the price of most 32-bit single-chip microcomputers is about 1.5 US dollars, which is still a long way from the overall erosion of the 8-bit microcontroller market. STMicroelectronics will play a pioneering role in eroding the 8-bit microcontroller market. Leading semiconductor manufacturers in the automotive electronics industry, including STMicroelectronics, Infineon, Renesas Electronics, Freescale, NXP, Texas Instruments, etc., have developed 32-bit microcontroller product lines and applications. In particular, with the further expansion of China's automotive electronics application market, the relevant 32-bit microcontroller companies based in the Chinese market will benefit from the future. 10.1 Inch Laptop,win10 Laptops,win11 Laptops Jingjiang Gisen Technology Co.,Ltd , https://www.jsgisentec.com
