Datong University World Group launches electric seat solution based on ST SPC560D40L3
The product showcases a high-performance power seat solution based on ST's SPC560D40L3 Power Architecture technology, developed by a leading electronic component distributor in the Asia-Pacific region. This advanced automotive microcontroller is specifically designed for next-generation embedded applications, leveraging the Power Architecture platform to deliver enhanced code density and efficient processing.
Built around the e200z0h core, the SPC560D family offers up to 48MHz operation, ensuring high performance with low power consumption. It integrates an LVE APU (Auxiliary Processing Unit) that optimizes code efficiency while supporting a wide range of automotive functions. The solution is backed by a robust development ecosystem, including software drivers and tools, making it easier for developers to implement and configure their systems.
China’s automotive market has been growing rapidly, with domestic sales projected to reach 25.5 million units in 2015 and 35 million by 2020, reflecting an average annual growth rate of about 7%. As car manufacturers seek to differentiate themselves, integrating advanced automation technologies into their products has become a key strategy.
Electric seat adjustment systems allow drivers to customize their seating position for optimal comfort and safety. These systems enable adjustments in multiple directions—front-to-back, height, and backrest angle—while more premium models also offer leg and lumbar support. Motor control ensures smooth and precise movement, enhancing user experience.
The system includes features such as 12-way seat adjustment, motor current monitoring, seat heating, and two sets of memory settings. It utilizes a 32-bit Power Architecture-based controller, ST L99DZ70, paired with H-bridge motors capable of handling 8A or 30A output. For heating, high-side drivers like ST VN7007AH and VN7010AJ are used, along with current sensing capabilities.
The design also incorporates a high-speed CAN bus transceiver operating at 1 Mbps, enabling fast and reliable communication between components. This makes the system ideal for modern vehicles requiring real-time control and data exchange.
The solution includes several key boards: a control board, driver board, and heating driver board, each playing a critical role in ensuring the system operates smoothly and efficiently. These components are designed to work together seamlessly, providing a reliable and scalable platform for automotive seat control systems.
