Can GS32-DSP Replace C2000? Analyzing China’s Domestic MCU Revolution in Automotive Electronics
Introduction: The Shift Towards Domestic Microcontrollers in China’s Automotive Industry
Texas Instruments’ (TI) C2000 series microcontrollers have long dominated the automotive electronics sector with their high-performance real-time control capabilities and flexible design. From vehicle electronic control systems to automotive lighting and powertrain domain controllers, C2000 has provided efficient and secure support through high-precision PWM, rapid signal processing, and hardware acceleration units.
However, as China’s automotive industry evolves, there’s a profound shift toward localization – from vehicle manufacturers and component suppliers to various materials – and chips are no exception. After experiencing chip shortages, Chinese automakers have begun supporting chip independence. Domestic MCU manufacturers are now challenging C2000’s market position through technological breakthroughs.
Shenzhen Gazsen Technology Co., Ltd. (hereafter referred to as “Gazsen Semiconductor”) has introduced the GS32-DSP series products with a core strategy of improving chip performance, expanding resources, and reducing costs. With Pin-to-Pin compatibility with TI’s C2000 as their market strategy, they’re providing a more competitive alternative for China’s automotive electronics industry.

C2000 is widely used in motor control, digital power, industrial automation, new energy, and automotive electronics, among many other scenarios. Its distinguishing feature is the integration of rich signal processing functions, such as high-precision PWM, fast ADC, and hardware acceleration units, making it the ideal choice for real-time control applications for an extended period.
In automotive electronics, C2000’s main applications include:
- Motor control
- Digital power control
- Vehicle status monitoring and more
The chip integrates logic blocks, reducing dependency on peripheral circuits and simplifying system design.
Part 2: Analyzing the Competitiveness of China’s Domestic MCU Industry
With the rapid rise of China’s new energy vehicle market and the push for localization policies, domestic MCU manufacturers are accelerating technological breakthroughs to challenge C2000’s dominance. Gazsen Semiconductor’s GS32-DSP series offers domestic automotive electronics companies a powerful alternative through Pin-to-Pin compatibility and technological innovation.
The GS32-DSP series covers diverse needs from cost-oriented to high-performance solutions, introducing alternatives that can compete with and even surpass C2000 in the automotive electronics field.
GS32-DSP Product Matrix
The currently mass-produced GS32-DSP series is divided into cost-oriented, general-purpose, and high-performance types:
Cost-Oriented Models
Products like GS32F0025H are equipped with GS-DSP100, with frequencies between 160MHz-240MHz, smaller eFlash and SRAM capacities, and various pin options including 48PIN. These models are compatible with the TI architecture while upgrading computing power and peripheral functions, suitable for low-cost body control applications.
General-Purpose Models
Products such as GS32F0039 are based on the GS-DSP100 core with increased main frequency, larger eFlash and SRAM capacities, and more pin options to meet general scenarios like HVAC and lighting control. Notably, these represent the first domestic alternative to TI C2000 automotive DSP products to complete both AEC-Q100 reliability and ASIL-B functional safety certifications, demonstrating Gazsen Semiconductor’s professionalism and commitment to the automotive sector.
High-Performance Models
Models like GS32FF65DKH, some equipped with dual GS-DSP300, reach frequencies of 400MHz with larger eFlash and SRAM capacities, supporting complex power management and high-performance applications.
The GS32 series is based on Gazsen’s independently developed GS32-DSP100 and GS32-DSP300 core architectures. Following the national trend of encouraging RISC-V ecosystem development, these products are based on RISC-V cores, integrating mixed signal processing units and real-time control algorithm accelerators with fully independent intellectual property rights, demonstrating technical advantages and product competitiveness beyond C2000 in fields like automotive electronics.

Within the hardware system, the GS32-DSP series offers a complete model layout, covering 100% of mainstream models, providing rich and suitable choices for customers with different requirements.
On the software side, the migration cost is minimal, with all key IPs and toolchains independently developed with complete intellectual property rights, such as the proprietary Current Loop Control Computing Unit (CLU) and Gazsen’s copyright-enhanced logic blocks (eCLB). This means that customers using C2000 can transition seamlessly without extensive effort, greatly reducing migration costs and making the transition process both easy and efficient.
Meanwhile, the GS32-DSP series has increased peripheral resource utilization by 30%, laying a solid foundation for supporting more complex control algorithms and higher real-time performance, better meeting diverse application requirements.
Beyond compatibility, the GS32-DSP series offers higher performance. Adopting the Gazsen GS-DSP100 core with deep customization optimization for real-time control, the GS32-DSP series features industrial and automotive-grade reliability, with significantly improved eFlash and computing power, demonstrating excellent performance in both stability and computational capability.
Beyond the products themselves, domestic manufacturers have service advantages. Gazsen Semiconductor’s senior technical team provides timely on-site support based on rich experience and professional knowledge, ensuring that customer issues during use are resolved, guaranteeing high product quality.
