NXP MCU Meets E/E Architecture and SDV Requirements
Traction Inverter Intelligent High-Precision Control Optimization

NXP Semiconductor (hereinafter NXP) realizes future electrification through its new MCU series, extending driving range and providing a smoother electric vehicle driving experience.

NXP Semiconductor announced on the 28th its new S32K39 series of automotive MCUs optimized for EV control applications.

The S32K39 MCU incorporates networking, security, and functional safety technologies that surpass conventional automotive MCUs.

Through this, it fulfills the requirements of zonal vehicle E/E architecture and Software-Defined Vehicle (SDV).

NXP's Battery Management System (BMS) and electric vehicle power inverter can provide end-to-end solutions for next-generation electric vehicles through the new MCU.

The high-performance S32K39 MCU is optimized for intelligent high-precision control of traction inverters that convert DC power from electric vehicle batteries to AC to drive modern traction motors.

The MCU supports both conventional insulated-gate bipolar transistor (IGBT) and new SiC and GaN technologies.

Using dual 200kHz control loops that improve power efficiency enables smaller, lighter, and more efficient inverters, while significantly extending the motor's driving range.

Additionally, controlling six-phase motors with improved output density and fault tolerance can enhance long-term reliability, and using ASIL D software resolvers together with integrated sine wave generators and sigma-delta converters eliminates external components, reducing overall system costs.

Combining the S32K39 with NXP's S32E real-time processor provides the flexibility to control up to four traction inverters as well as implement advanced traction functions for all-wheel drive electric vehicles.

The S32K39 series adopts a multipurpose architecture and is suitable for various electric vehicle applications including traction inverter control such as battery management (BMS), onboard charging (OBC), and DC/DC conversion.

With hardware isolation, time-sensitive networking, and advanced encryption capabilities, it is also well-suited for supporting SDV and zonal architecture.

Allan Mcauslin, Head of Vehicle Control and Electrification at NXP Semiconductor, stated, "The S32K39 MCU attractively combines modern technologies to provide automakers with the flexibility and scalability that enables deployment of the latest electrification technologies and accelerates electric vehicle development," adding, "NXP is taking the lead in providing a comprehensive portfolio of complementary solutions that can help deliver better electric vehicle driving experiences to customers and accelerate the electric vehicle revolution."
