New Choices for Domestic Automotive Chips: HK32A040

As the selection of automotive-grade chips shifts from foreign manufacturers’ monopoly to gradually introducing domestic chips, a batch of chip products that can achieve domestic substitution has emerged. The automotive-grade industry has higher stability requirements for chips than consumer and industrial products, so the selection of automotive-grade chips needs to consider more factors, including technical parameters, application scenarios, supply chain stability, cost control, etc. Among the most important key points are: automotive-grade certification: automotive-grade chips need to pass AEC-Q100 certification, which means that the chips must meet strict quality and reliability standards. Months of testing involve complex testing and verification processes to ensure product stability and durability under extreme temperature, humidity, vibration, and electromagnetic interference conditions.

Compatibility and integration issues: Automotive-grade chips need to be compatible with other electronic systems in vehicles, which involves complex software and hardware integration work. Ensuring that all systems can work together seamlessly is a challenge.

Safety and reliability: The safety and reliability of automotive-grade chips are crucial. Any failure or misuse could lead to serious safety incidents. Therefore, strict testing and verification are required during the development process.

Cost control: While meeting all technical and safety requirements, controlling costs is also a challenge. Cost-effective solutions need to be found to ensure the market competitiveness of products. Recently, the price game between major automotive brands and suppliers has attracted industry attention.

Supply chain management: Ensuring the stability and reliability of the supply chain, especially in the context of complex international situations, from design to production packaging, domestic chips significantly reduce dependence on overseas suppliers, making it the best alternative.

How to choose an MCU manufacturer? According to the following three criteria:

The first criterion is the reusability of chip code, the higher the better. For domestic substitution, as much old code as possible can be reused. If it’s newly developed, it can also be reused in future expansions.

The second criterion is pin compatibility. If different configurations of MCUs with the same package, even MCUs of different series and levels, are pin compatible, then when a need arises to upgrade or downgrade MCU specifications during development, they can be directly replaced without redoing the board, which is very convenient.

The third criterion is simpler; if you have contacted the manufacturer or agent about the selection and have not been able to reach them, then put them at the back of the line. The ones you have contacted that provide fast and good service are the first choice.

After a comparison and screening, Hangshun chip automotive-grade MCU has emerged:

Automotive-grade requirements: Hangshun chip’s automotive-grade chip has passed AEC-Q100 certification, which is the test certification of the International Automotive Electronics Association, meaning that the product meets stringent requirements in terms of service life, stability, operating temperature, PPM, etc. In addition, Hangshun chip follows the ISO 26262 full process standard, which covers the entire product lifecycle, ensuring functional safety.

Compatibility and integration issues: When designing the MCU, Hangshun chip not only ensures hardware compatibility with certain international manufacturers’ chips but also achieves over 95% software compatibility. This design allows customers to quickly switch solutions, saving a lot of time and costs. At the same time, Hangshun chip integrates CRC, AES, HASH, and TRNG hardware computing units to verify the correctness and integrity of data transmission or storage, as well as to implement encryption and decryption of Flash data.

Safety and reliability: Hangshun chip’s automotive-grade chip uses a high-performance ARM Cortex-M3/M0 core, and the chip is developed and produced domestically. The chip includes a self-developed floating-point computation coprocessor, or a hardware acceleration module for division and square root operations, which has strong data processing capabilities. Hangshun chip has passed AEC-Q100 automotive certification and complies with ISO 9001 and IATF 16949 quality management system certifications, and the accompanying R&D and management capabilities have also been validated.

Quality cost control: Hangshun chip has achieved cost control and efficiency improvement through internal automation and modularization strategies. Hangshun chip has developed an automated software platform that significantly enhances project efficiency and R&D cycles, shortening project time by 30% to 50%. In addition, Hangshun chip realizes rapid product development through modularization and standardization, ensuring product consistency and reliability.

Supply chain management: Hangshun chip adopts a diversified strategy in supply chain management, rather than relying solely on one wafer factory for production. This diversification strategy not only helps Hangshun chip maintain supply chain stability but also flexibly responds to market changes, ensuring that the company can quickly adjust production and supply strategies in the face of emergencies.
