Learn More About the S32K Family
What are the main electric vehicle (EV) applications for each S32K3 family member?
- The S32K35 and S32K37 are ideal for battery management applications.
- The S32K39 is ideal for traction inverter applications, such as combined inverters or OBC and DC-DC applications.
- The S32K32 and S32K34 are optimized for 400 V BMS.
What are the target motor control applications for the S32K3 and the S32K9?
The S32K39 targets EV traction control inverters, offering optimized performance for the application, as well as the ability to combine on-board charger (OBC) and DCDC applications with advanced motor control peripherals.
The other S32K family members target motor control use cases in the chassis and body.
Is the S32K3 family appropriate for Brushless DC (BLDC), Permanent Magnet Synchronous Motor (PMSM) and AC Induction Motor (ACIM) motor drives?
With specialized peripherals such as eMIOS, Logic Control Unit (LCU), Body Cross-Triggering Unit (BCTU), and a large set of ADC converters, motor control applications are easily and safely deployed in S32K3 MCUs.
What applications can the S32K3 family perform in zonal vehicle architectures?
The S32K3 family is optimized for zone controllers performing IO aggregation and body functions. The MCUs are optimized for implementing actuation functions in the zone controller itself or in the connected edge nodes.
