How can imported "chip" products help domestic substitution under tariff pressure?
Release time：2025-04-21 Source：Original
In April 2025, the Sino-US tariff game ushered in a new round of escalation - following the 104% comprehensive tariff on China's semiconductor equipment exported to the United States in March, China announced countermeasures on April 9, imposing an 84% tariff on semiconductor equipment and chips originating in the United States. It is worth noting that China adopts the new regulation of "determining the origin of the tape-out", that is, the country of origin is determined based on the place of manufacture rather than the post-packaging and testing site, resulting in the core products of TI, ADI and other companies in the United States having to bear an additional 125% tariff due to the wafer tape-out process in the United States, resulting in their selling price in China generally doubling compared with before. Under the dual pressure of technical barriers and supply chain risks, domestic subsistence has become an inevitable choice for industrial breakthroughs.
Hunan Jinxin Electronic Technology Co., Ltd
The company has many years of technology accumulation and has built a 100% localized supply chain, from architecture design to mass production and delivery, the whole process is independent and controllable, completely getting rid of dependence on overseas technology systems. The company has launched three series of DSP products and single-core/multi-core SoCs that can be adapted to multiple scenarios such as new energy vehicles, industrial control, and consumer electronics. Its many automotive-grade products have passed AEC-Q100 certification, and their performance is benchmarked against international first-tier brands, while also providing customized development services and full-cycle technical support to help customers achieve system efficiency improvement and resource optimization.
AVP32F003x: 120MHz high-performance 32-bit floating-point DSP, defining the benchmark for autonomous and controllable "cores"
Powerful computing power and real-time processing of complex algorithms
The AVP32F003x is equipped with a 32-bit A2000 DSP core clocked at 120MHz, integrating IEEE 754 single-precision floating-point unit (FPU) and trigonometric mathematical unit (TMU) to support real-time operation of complex algorithms such as nonlinear proportional-integral-differential (NLPID) control. At the same time, the CLA with a main frequency of 120MHz can process real-time control tasks independently of the CPU in parallel, compressing the calculation period of the motor current loop to less than 1μs, effectively improving the synchronization accuracy of the multi-axis servo system.
Accurate simulation and high-resolution control
The AVP32F003x integrates three 4MSPS 12-bit ADCs that can handle up to 23 external channels, each with four integrated post-processing blocks (PPBs) to accurately acquire analog signals and ensure data accuracy even in weak signals and complex interference environments. In power management applications, its high-precision ADC can monitor voltage, current, and other parameters in real time, and with 16 ePWM channels (including 8 channels with high-resolution capabilities and 150ps resolution), it can achieve fine control of power stages.
Rich peripherals and full-scenario communication adaptation
AVP32F003X integrates 1 power management bus (PMBus) interface, 2 internal integrated circuit (I2C) ports, 1 controller area network (CAN/DCAN) bus port, 1 controller area network (CAN FD/MCAN) bus port with flexible data rates, 2 serial peripheral interface (SPI) ports, and other rich communication interfaces, making it easy to interconnect between devices, whether it is close communication with sensors, actuators, or via CAN The bus realizes long-distance data transmission and can operate stably.
Under the tariff challenge, it is a key opportunity for domestic chips to break out of the cocoon and become butterflies. Jinxin Electronics will continue to increase investment in R&D and innovation with core technology breakthroughs as the engine, deeply integrate DSP kernel design, efficient algorithm development and ecological platform construction, actively work with upstream and downstream partners in the industrial chain to gather localization and innovation synergy, build a solid safety foundation in the reconstruction of the global supply chain, and help China's semiconductor industry shine on the world stage!
