"At present, the ARM Cortex-M series microcontroller has no disputeously occupied 32-bit MCU products, of which low power Cortex-M0 / M0 + to the current M-series's highest performance Cortex-M7, They all have a place in the market, however, if they are said to motor control, power management, embedded audio, Coretex-M4 series of microcontrollers are undoubtedly the most widely used, most popular series, and the reason It is still in the integrated FPU unit, with DSP processing power, performance can exceed current 16-bit DSP chips, a little 32-bit DSP chip, always says that there is a good processing performance under the premise of maintaining energy efficiency, but also has universal MCU Powerful IO-handed control capabilities, the application is wide enough. The global Cortex-M4 series microcontroller product is still very much, this part has time to talk, today we only say in China, based on Cortex-M4 What few of the controller manufacturers? What is more powerful?
Everyone knows that the chip is not an easy thing, it is really burning money, not only the technology, especially the microcontroller product, because ARM's Cortex-M series microcontroller ecotrial is wide, In addition to many of themselves have their own products or their own strength, they basically rely on authorized IP and redesign, and this authorization fee is a unmisstive expense, Chinese dare to play, and implement a mobile company. Not a few, and the manufacturer of the ARM Cortex-M4 series microcontroller is less, and all, it is basically Taiwan's new Tang, Beijing's Zhaoyi, and Shanghai's Xiangli.
New Tang M453 series
New Tang should not be unfamiliar, this is the old chip manufacturer of China, starting from 8051, there is ARM7 / 9 series, Cortex-M0 / M4 series, etc., product line is very rich, the product's application coverage industry is also very widespread , Automotive electronics, industrial electronics, consumer electronics, etc., the strength is still guaranteed, in which the product line based on the Cortex-M4 series mainly has M4 series, NUC442, NUC505 series.
I just have a USB and a product of the M4 series, which belongs to the USB and the CAN function series, which belongs to the most rich in the new Tang's M4 series, which can be applied to industrial control, industrial automation. , Consumer products, network equipment, energy power, motor control, etc.
The main control model of the board is M453VG6AE, the internal integration 256KB Flash, 32KB RAM, using LQFP-100 package, is the most bundled in the M4 series, as shown below.
However, the maximum frequency of M453VG6AE only supports 72MHz. I don't know if the cause of the process is limited, considering power consumption and the application of the product. After all, the new Tang also has a higher frequency Cortex-M4 product NUC442, NUC505 series, Think about it, it may be in order to more divide the product line, so that engineers can have a cost-effectiveness from the head to the steps, how to have cost performance.
The new Tang's microcontroller actually develops environmental use is still very convenient. After all, it is also an old manufacturer, hardware development tool, in addition to board, onboard debugger NU-Link-Me, also supports third-party JLINK and other debugging tools, and IDE tool, universal third-party ARM Keil, IAR, and Coide are OK, the focus is more fully available, there is a Chinese specification, which is convenient for engineers.
As for the specific development process of the development board, this article does not speak more, you can refer to the board evaluation before the New Tang, basically similar:

Xiangli Microelectronics Marco Polo TG401
After the New Tang of Taiwan, let's take a look at one of the two two things in the mainland. This is the first manufacturer of the mainland to release the ARM Cortex-M4 microcontroller. This company is even more powerful. In 2014, it was established. It was located in Shanghai Zhangjiang Science and Technology Park. It is a founder of this company. It is a technical big cow, which was the founding of the Intel China Institute and his first principal.
Their first model Based on the ARM Cortex-M4 processor product Marco Polo TG401 called the first domestic model, I don't know if this call will fall, I think it is more appropriate to say that the first paragraph of the mainland is more appropriate.
The TG401 based on ARM Cortex-M4 has powerful computing capabilities and rich features, the maximum main frequency is 150MHz, integrated with 1MB Flash, 512KB RAM, peripheral IO interface resources, and analog interface resources are very rich, 1 USB, 2-way SD / SDIO, 4-way UART, 3-way SPI, support up to 16-channel PWM output; integrated up to 24 channels 12Bit ADC, ADC acquisition frequency up to 2MSPS, support 8-bit parallel and 3-wire / 4_wire serial The LCD interface, etc., the specific function can refer to the following form.
Xiangli Microelectronics also designed a practical development board for Marco Polo TG401 microcontroller, the onboard circuit includes sensor applications, audio applications, USB applications, microSD card applications, basic fences of several special features of the master Applications, suitable for engineers to evaluate the performance functions of microcontrollers, but different from many panels we now have a board debugger, TG401 requires external hardware emulator to debug.
Since there is no real thing in the hands of the author, there is not much speech, but from the information of the board card, this area can be exposed to Xiang Microelectronics still in the starting stage, the online can only find some basic With the specifications of the microcontroller chip, there is no practical routine reference, unclear whether it is not published online or not, there is no information available in this area.
The Marco Polo TG401 microcontroller also supports third-party Keil, IAR, GCC IDE tools, and also supports USB and UART update firmware, support OTA update firmware.
In addition to supporting common JLINK, more unexpected hardware debugging tools, it also fully supports Rodbach's high-end debugger Trace32 (About Trace32 Debugger, you can refer to: Aristocrat in debugging - Raotbach μTrace, Greatly improve the debugging efficiency of leaving the hairman.

Zhaoyi GD32F450
Hey, Zhaoyi GD32F4 series microcontroller can only be counted as a microcontroller of the second ARM Cortex-M4 in the mainland. The first I thought that the Magui's GD32F4 series is the first in the mainland. After all, the author first Get the extension F4 series products. In fact, it is almost the time, and it may be very depressed by the first ARM Cortex-M4 microcontroller, the first ARM Cortex-M4 microcontroller, which is called the first ARM Cortex-M4 microcontroller. If you really have a true microcontroller to develop quantities, I think that in addition to hardware products itself, the supporting information must also be complete. This effort to be more expensive after several years, after all, after all The human hand put it is in that.
The mega board that I got in my hand is a full-featured board GD32450I-Eval that they officially launched. It is understood that the friends who know the exclusive full-featured panel should be unfamiliar, which is basically designed in the style of the ST, Therefore, all functions of the microcontroller basically present on the peripheral of the board, including a 4.3-inch LCD module (480 * 272), camera module, audio circuit, ADC / DAC, MicroSD card, Ethernet interface, USB HS / FS interface, GD-LINK, UART, CAN interfaces, etc. can make engineers to evaluate microcontrollers.
