New product recommendation: NXP’s S32K39/37 MCU for electrification applications

S32K39-37 is a purpose-built device addressing the new electric vehicle (EV) needs with a compelling combination of performance, integration, networking, security and functional safety capabilities.
S32K39 has enough compute power to support up to 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 new zonal vehicle architectures. It also 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.
