Technical goal: Collaborative chip computing to make embedded development easier
The company is focusing on the two major technological foundations of "chips" and "algorithms", and is simultaneously making efforts and continuously iterating. By utilizing advanced technology and efficient design, high computing power density is achieved, and a rich high-performance algorithm library is accumulated through application, forming a core technological advantage of combining software and hardware. The company is building a comprehensive software ecosystem, empowering terminal applications with algorithms, providing integrated software and hardware solutions, and achieving a win-win value of cost reduction, efficiency improvement, and acceleration.
Using YSPRING chips, development only takes one day "- this is not only the product slogan, but also Huichun's ultimate pursuit of embedded development efficiency.

In terms of supply chain, we have official ARM core authorization (M0/M23/M4F full coverage) and adopt advanced processes of 28nm/40nm/55nm and 110nm/180nm. Based on our independently controllable supply chain, we have independently developed a complete set of development tool chains and established our own packaging and testing factory to ensure stable and controllable quality and delivery time.
2、 Strategic Plan for the Development of Motor Control Industry
The global motor control MCU market is undergoing an accelerated transformation from 8-bit brushed to 32-bit brushless FOC/BLDC. At the same time, emerging scenarios such as humanoid robots have driven the annual growth rate of the micro servo motor market to over 15%, with a single humanoid robot requiring more than 40 servo joints. To align with industrial development, Huichun Technology will adopt a four step development strategy in the field of electric motors.

3、 Motor main control MCU product SOC
The YSMOTO motor specific SOC product matrix covers two major architectures: MCU+Pre Driver, divided into three performance levels of 48MHz/64MHz/120MHz according to the main frequency. It provides unlimited power external drive solutions and integrated pre drive integrated solutions, fully adapting to the control needs of full field electric machines from high voltage and high power to low voltage and low power.
MCU+Pre Driver Product Matrix
The product matrix covers three major series: the pure MCU series (F031/M032/M120/M410) provides flexible external drive solutions with unlimited power; The MD series integrates on-chip pre drivers, achieving an integrated design of "MCU+driver", effectively simplifying PCB wiring and peripheral circuits, and reducing BOM costs. The entire series supports a wide temperature range of -40~105 ℃, meeting industrial grade quality requirements.
4、 Main recommended solutions and advantages for motor applications
The main motor control solution is based on the core competitiveness of "original chip+original algorithm", covering two major technical routes of FOC sine wave and BLDC square wave, providing a full range of motor control solutions from low-voltage FOC to high-voltage FOC, from inductive BLDC to non inductive BLDC.
Application of FOC string wave scheme
The FOC sine wave scheme is based on sine wave frequency conversion speed regulation, and has complete functions such as zero speed closed-loop starting, forward and reverse wind starting, constant power output, current control and overcurrent protection, stall/stall protection, overvoltage/undervoltage protection, etc. It runs smoothly, has low noise, and high efficiency.

Application of BLDC square wave scheme
The BLDC square wave scheme is characterized by reliable start-up performance and voltage adaptation, supporting core functions such as static initial position detection (noise free start-up), ADC zero crossing detection control, soft and hard braking, and fast start-up (40ms full speed operation). The control parameters are flexible and customizable, and are widely used in power tools and personal care products.
