Datong University World Group launches electric seat solution based on ST SPC560D40L3
The company is dedicated to offering a high-performance power seat solution based on ST's SPC560D40L3 Power Architecture technology, positioning itself as a leading electronic component distributor in the Asia-Pacific region. This innovative solution leverages the advanced capabilities of the SPC560D family, which is specifically designed for next-generation automotive microcontrollers and embedded applications. The e200z0h core provides improved code density through its LVE APU, delivering high performance at up to 48MHz while maintaining low power consumption. It integrates seamlessly with Power Architecture development tools and software drivers, making it easier for developers to implement their operating systems and code configurations.
China’s automotive market is experiencing rapid growth, with projections showing domestic sales reaching 25.5 million units in 2015 and 35 million by 2020—an average annual growth rate of around 7%. As automakers seek to differentiate themselves, converting advanced automation technologies into competitive advantages has become a key product strategy.
During driving, electric seats can be adjusted at any time, allowing drivers to find a more comfortable seating position, reduce fatigue, and enhance both safety and comfort. The electric seat system enables adjustments in multiple directions—front-to-back, up-and-down, and reclining. Higher-end models also offer leg support and lumbar adjustment features.
The system includes a 12-way adjustment mechanism that allows for front-to-back movement, backrest tilting, seat height, horizontal movement, counter-clockwise rotation, and waist height and front-to-back adjustments. It also supports motor current detection, seat heating, and two sets of seat memory functions.
Key features of the solution include a 32-bit Power Architecture-based car controller, the ST L99DZ70; H-Bridge motors capable of 8A or 30A output; high-side drive ICs (ST VN7007AH and VN7010AJ) for seat heating with current sensing; and a high-speed CAN bus transceiver supporting data rates up to 1Mbps.
This comprehensive solution is ideal for modern vehicles looking to enhance driver comfort and functionality while maintaining reliability and performance. The control board, driver board, and heating driver board are all designed for efficient integration and operation, ensuring smooth and precise control of the electric seat system.
