In the face of the huge MCU race in the market, it is not surprising that MCU vendors have cooperated with ARM. As the demand for Cortex continues to increase in the market, more customers hope to use a convenient platform to shorten their development cycle. ARM's ecosystem enables development tools, middleware, drives, etc. to be easily accessible, so there are The sentence at the beginning of the article. However, Fujitsu's FM3 MCU series really makes us shine. Although Fujitsu is one of the first vendors to introduce Cortex-M3 MCUs, how can Fujitsu be the next to the other peers? And listen to me. As we all know, Fujitsu has a reputation for electromechanical control applications in China. Recently, Fujitsu Semiconductor has launched a fifth new FM3 series of 32-bit RISC microcontrollers based on the ARM® CortexTM-M3 processor core. In the fifth wave, there are basic product group MB9B520M series, including MB9BF524MPMC and other products, a total of 72 models, of course, this must be applied to industrial control, home appliances, office automation equipment, etc.; at the same time, also introduced suitable Battery-powered mobile products, digital home appliances, and electronic healthcare products, the low-power product group MB9A150R series 21 models. Photo 1. MB9520M Series Photo 2. MB9A150R Series This wave of products is on the line, telling you that Fujitsu Semiconductor's ARM® CortexTM-M3 processor-based microcontroller lineup will be expanded to 463 models. However, according to reliable sources, Fujitsu Semiconductor will continue to expand the FM3 series product line in the future, and plans to reach 500 models by the end of 2012. Closer to home, where is this wave of products unique? I personally believe that the MB9B520M series will show great strength in frequency conversion. Why do you say this? Let's not say that the previous 180-degree DC frequency conversion scheme is being sought after by many Chinese white goods manufacturers. The performance of these basic products can be confirmed. The original 40MHz basic group product line is added. A 72MHz product line. This has to say that in addition to the inverter control function, this series of products is also equipped with CAN, USB 2.0, real-time clock and flash memory with a capacity of between 96KB and 288KB. The package has 48 pins to 96 pins for customers to choose from. . Around these, personally think that it is indeed a relatively good choice in the application of home appliance frequency conversion control, such as air-conditioning, refrigerators, washing machines and human-machine interface control in general consumer electronics can do the most. In addition to being used in household appliances, the basic group products can also be used for motor control in office automation equipment such as printers and copiers, and CAN network communication between various industrial devices. Also worth mentioning is the peripheral peripherals developed by the FM3 family for FR microcontrollers. Although this fact has been reported countless times, and the above conversions can be explained, I still need to mention that the integration of more advanced support for high-precision motor control peripherals strengthens the series. Various high-precision, high-speed 12-bit A/D converters, various built-in 2 units and up to 26 channels of A/D converters, and built-in quad counter (motor rotary phase detection counter) can be rotated at the hardware level Phase detection, combined with software layer control procedures, reduces processor operating load. This product is more suitable for energy efficient inverter systems. This powerful peripheral does not need to be described in more languages. The report on the network is well known to everyone. All of the above mentioned are basic group products. The low-power products in this wave are also excellent. The built-in user-friendly power-saving mode can be used for the HDMI-CEC macro of the user interface in AV equipment and other devices. The flash dual operation function, low power consumption does not require more modification. Perhaps after reading the above introduction, everyone has a better understanding of this series of products, I will show you the new product roadmap of this family. From the picture, we can see that Fujitsu Semiconductor has begun to work hard from the four major directions, to seize the market depends on the first machine and complete product supply, have to say, really look forward to Fujitsu at the end of the year, a larger new product release!
