Overview
The RDS12VR is a solution engineered for window lift, power windows, and sun roof systems.
Developed in partnership with Tongji University and based on the 16-bit S12 MagniV® S12VR mixed-signal microcontrollers, the RDS12VR offers control by multiple LIN salve nodes or LIN master node, through the easy-to-control Graphics User Interface (GUI).
The RDS12VR reduces unnecessary external components, lowers the total bill of material (BoM), improves system quality, and saves space in automotive applications through a smaller PCB. The RDS12VR solution includes hardware for real door/window in-vehicle applications, as well as software including anti-pinch algorithms and low-level S12VR drivers for reducing time to market.

Features
Features
- Window manual/automatic up/down, automatic up/down with stop function
- Anti-pinch in both manual/automatic mode, anti-pinch region and force can be adjusted
- Stuck detection out of anti-pinch region, motor overload protection
- Soft stop when window is close to the top/bottom
- Self learning, calibration by updating the window/motor parameters stored in EEPROM
- Use hall sensor as well as current sense to judge anti-pinch in algorithm
Power
- Fault diagnosis, indicating low voltage, over voltage/current/temperature etc.
- Low power mode (leveraging S12VR low power mode) to reduce power consumption
GUI
- Easy-to-control GUI, set the parameters and get the status
- Window lift can be controlled either by multiple LIN salve nodes or LIN master node, through GUI
