The S32K39 MCU from NXP is purpose-built to address electric-vehicle (EV) traction-inverter control needs with a combination of performance, integration, networking, security, and functional-safety capabilities. The MCU can support one six-phase or two three-phase motors, controlled by over-200-kHz control loops, while hosting AI/ML algorithms or other monitoring applications. It supports remote smart actuation applications using time-sensitive networking (TSN) Ethernet for zonal vehicle architectures, and reduces system cost with ASIL D software resolver and analog integration.

The S32K37 high-compute capabilities are ideal for high-end battery-management systems (BMS) applications, as well as other EV power inverter and hybrid-electric-vehicle (HEV) applications.
