S32K39/37 MCUs for Electrification Applications
NXP's MCUs offer a compelling combination of performance, integration, networking, security, and functional safety capabilities
NXP's S32K39/37 is a purpose-built device addressing electric vehicle (EV) traction inverter control needs with a compelling combination of performance, integration, networking, security, and functional safety capabilities.
It has enough computer power to 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. It also reduces system cost with ASIL D software resolver and analog integration.
The portfolio scalability and future-proof features, such as advanced security and software, tools, and third-party development support, allow developers to standardize the S32K39/37 series for their end-product platforms, maximizing the reuse of hardware and software. This functionality also reduces the time-to-market of these chips.
The S32K37's high-computer capabilities are ideal for high-end battery management systems (BMS) applications.
