It is understood that the Arm® Cortex®-M7 core provides the GD32H7 series MCU with processing capabilities up to 600MHz, equipped with 4MB on-chip Flash and 1MB SRAM, supporting large-capacity code storage. It has a built-in 512KB ultra-large tight coupling memory TCM and a 64KB L1-Cache high-speed cache, as well as advanced hardware DSP, double-precision FPU, trigonometric functions, and digital filters to achieve optimal processing efficiency.
Compared with existing high-performance products, Jin Guangyi believes that the GD32H7 series MCU not only achieves a significant increase in performance but also significantly expands peripheral resources and unprecedentedly enhances analog performance. It integrates two 14-bit ADCs with a sampling rate as high as 4MSPS and one 12-bit ADC with a sampling rate as high as 5.3MSPS, providing high-precision sampling rates and rapid response in applications such as graphic image display, AI algorithm support, motor control, and photovoltaic energy storage. Three CAN-FD interfaces and two Ethernet controllers also provide good advantages for industrial network cards, frequency converters, and servo drives.
In addition, cost is also a major advantage of this product. The GD32H7 series MCU adopts the industry-leading process technology, so the cost advantage is very obvious compared to foreign competitors. At the same time, GigaDevice has also optimized a variety of IPs, including digital IPs and analog IPs, greatly improving integration, allowing more IPs to be integrated in the same area.
It is worth noting that the GD32H7 is also the first M7 core MCU launched by GigaDevice in China. So why haven't other domestic MCU manufacturers made this layout? Jin Guangyi believes that on the one hand, the technical requirements for ultra-high-end performance MCUs are higher. For example, the higher the MCU frequency, the better control of its stability, heat dissipation, and power consumption is required. Domestic MCUs are more inclined to the mid-to-low end, and most are used in markets that can quickly increase in volume, while the high-end MCU market threshold has exacerbated the long-term existence of technical barriers.On the other hand, GigaDevice's GD32 MCU is a leader in China's high-performance general-purpose microcontroller field, with the largest family of Arm architecture MCUs in China. Its products cover a series of general-purpose MCU products with cores such as Arm® Cortex®-M3, M4, M23, M33, etc., and have achieved coverage of low/mid/high-end products. On this basis, the GD32H7 is a new product that GigaDevice continues to move towards more high-end products.
Jin Guangyi pointed out that the launch of the GD32H7 has profound significance for the MCU market. As China's first super high-performance MCU product with an M7 core, it continues to consolidate GigaDevice's leading market position with a very competitive cost-performance advantage from performance, integrated resources, to cost, and further perfects GigaDevice's super high-performance MCU product map, and continues to interpret the path of domestic substitution and popularization of super high-performance MCUs.
At the same time, the GD32H7 provides richer development options for high-end needs, supports innovative scenarios such as complex calculations, AI, and multimedia technology, and comprehensively promotes the application and popularization of MCUs in cutting-edge fields.
In terms of application reference design, the GD32H759I-EVAL full-function evaluation board uses the GD32H759IMK6 as the main control MCU, and now supports a variety of mainstream real-time operating systems (RTOS), graphical user interfaces (GUIs), and embedded AI algorithms in the industry, including Zephyr, AWS, and Azure RTOS.
At the same time as the exhibition, there is also a GUI development demonstration kit designed based on the GD32H7, which can demonstrate LCD display, touch control, QR code, image decoding, file browsing and other functions. With the upper computer simulator, it is convenient for customers to design and develop UI on the PC, as well as logical function verification. By connecting industrial control equipment such as PLCs, frequency converters, and instruments, as well as home control platforms, through serial ports, Ethernet, and CAN bus communication interfaces, users can interact with terminal devices in the workplace and home in a more intelligent, relaxed, and intuitive way.
"GigaDevice is also actively deploying dual-core and multi-core processor architectures. These super high-performance MCU products will further increase the coverage of AI on edge devices in the future. In addition, future products will also integrate security technologies such as TrustZone and Lockstep to meet the security requirements of more advanced applications," Jin Guangyi added.

In May of this year, GigaDevice took the lead in launching the SPI NOR Flash with a 3mm × 3mm × 0.4mm FO-USON8 package - GD25LE128EXH. Its maximum thickness is only 0.4mm, and the capacity is up to 128Mb. It is currently the smallest plastic package product that the industry can achieve at this capacity, which can meet the needs of large-capacity code storage while providing the greatest degree of compact design freedom.
Chen Hui said that for Flash, there are many different needs for different applications. We have done a lot of work in product layout, from product performance, capacity, including packaging, reliability, power consumption, and other aspects, there are different product series to meet different needs.
In recent years, with the rapid development of applications such as the Internet of Things, wearables, health monitoring, and network communications, there is a need to provide rich functions in a delicate and compact product form, while also having extremely low power consumption to ensure the long-term operation of the product. As an important code storage unit in these devices, SPI NOR Flash needs to provide smaller, thinner, and lighter product options to meet these constantly changing application needs.
Previously, the ultra-small size 3mm × 3mm × 0.4mm FO-USON8 package 128Mb SPI NOR Flash was also a new packaging form made in response to the industry's requirements for miniaturization and high integration in new application fields. The low power consumption characteristics of the first product GD25LE128EXH based on this packaging technology also make it suitable for any battery-powered product design.
Chen Hui pointed out in the interview that with the continuous upgrade of smart devices, GigaDevice foresees that the demand for large-capacity, small-size, and low-power SPI NOR Flash products will continue to grow. In response to this trend, the company is planning to develop other storage products with other capacities and smaller sizes through advanced packaging and storage technology to provide customers with more diverse options.
In addition, GigaDevice's storage products have also been laid out in the automotive field.It is well known that automotive chips have extremely high requirements for their design and reliability, which takes at least over three years from planning to mass production, with an even longer investment cycle and higher technical requirements.
Firstly, automotive electronics need to pass automotive standards certifications, including AEC-Q100, IATF16949, ISO26262, etc.; secondly, chips must pass various rigorous reliability tests before leaving the factory; in addition, the long-term supply commitment of chip products, service support during the product life cycle, and the consistency of product planning, all these have put forward strict requirements for car manufacturers and any enterprises in the automotive electronics supply chain. At the same time, automotive chips also require suppliers to provide high-quality assurance for the chips, which requires strict management processes, timely listening to market and customer feedback, and strict control of product quality.
In response to this, from R&D to production, GigaDevice adopts a zero-defect (Zero Defect) quality control philosophy to implement complete management and close attention to all projects, tracking and ensuring the reliability of the product throughout its life cycle.
As a chip manufacturer that started from consumer electronics, GigaDevice has focused on the automotive market since 2015, and in recent years, it has continuously increased R&D investment, actively developed the market, and provided a rich and high-quality automotive-grade flash memory, which has been recognized by partners and mainstream car manufacturers.

In conclusion, in recent years, with the changes in supply and demand, the chip market is experiencing unprecedented changes. As a leader in domestic memory and MCU, how is GigaDevice overcoming the impact brought by the overall environment? How to deal with market cycle fluctuations?
Chen Hui believes that as a global Fabless company, GigaDevice has done a lot of homework since its establishment and has made full preparations in the semiconductor supply chain. In response to the large shortage in 2020 and 2021, we have sufficient backups from raw materials to manufacturers, packaging and testing factories, and other links in the entire industry chain, ensuring the stability of supply.
Jin Guangyi shared around "diversification," pointing out that it is necessary to ensure supply through diversification of products, markets, regions, and supply chains. Especially in terms of supply chain diversification, our MCUs are now produced in China and overseas simultaneously, including wafer factories and packaging and testing. At present, we have 7 wafer factories and 14 packaging and testing backend factories for our MCUs. With so many production resources, we have a very sufficient supply capacity, which will not be easily affected by the supply and demand relationship, enhancing the resilience of supply and ensuring the foundation for our long-term development.
He pointed out that to make general products, it is necessary to have a diversified supply capability in order to cover more applications. GigaDevice also relies on such a strategy to go through the low cycle and achieve continuous growth.
