NXP introduces high-performance S32K39 series MCU to support a new generation of electrified applications

     NXP Semiconductor announced the launch of its new S32K39 family of Automotive Microcontrollers (MCUS), which are optimized for electric vehicle (EV) control applications. The high-speed, high-resolution control of the new generation of S32K39 MCU improves energy efficiency and provides a smoother EV driving experience while extending driving range to meet future electrification needs. S32K39 MCU network, information security and functional security beyond traditional car MCU, can meet regional automotive E/E architecture and software defined vehicle needs. With the new MCU, NXP's battery management system (BMS) and EV-functional inverters provide end-to-end solutions for next-generation EVs.

     S32K39 high-performance MCU is optimized for intelligent, high-precision control of traction inverters, which can convert direct current of electric vehicle batteries into alternating current to drive modern traction motors. The series MCU supports both traditional insulated gate bipolar transistors (IGBTs) and new silicon carbide (SiC) and gallium nitride (GaN) technologies. The S32K39 High performance MCU improves energy efficiency with dual 200 kHz control loops and a smaller, lighter, more efficient inverter with longer driving range.

     The series controls six-phase motors to improve power density and fault tolerance and maintain long-term high reliability. In addition, the series features secure ASIL D soft decoding and integrated sine wave generators with Delta-Sigma ADC, eliminating the need for external components and reducing system costs. When combined with the NXP S32E real-time processor, the S32K39 also allows for flexible control of up to four traction inverters and the ability to implement advanced traction functions for 4-wheel-drive electric vehicles with this configuration.

     The S32K39 series uses a multifunctional architecture, so in addition to traction inverter control, it is suitable for many other EV applications, including battery management (BMS), on-board charging (OBC), and DC/DC conversion. Hardware isolation, time-sensitive networking, and advanced encryption are also supported, and are fully prepared to support software-defined vehicle and regional architectures.

     Allan Mcauslin, Director, Automotive Control and Electrification, NXP Semiconductor, said: "The S32K39 MCU integrates multiple advanced technologies to provide automakers with tremendous flexibility and scalability to accelerate the development of electric vehicles and the deployment of new technologies in electrification. "With a comprehensive portfolio of complementary solutions, NXP is leading industry trends to provide customers with a better electric vehicle driving experience while accelerating the electric vehicle revolution."
