At the recent electronica trade event in Munich, NXP Semiconductors unveiled its S32K39 series of automotive MCUs, which are optimized for advanced electric-vehicle (EV) system control applications. Integrating networking, security, and functional-safety capabilities, the MCUs leverage NXP’s battery-management system (BMS) and EV power inverter solutions, and are optimized to intelligently and precisely control traction inverters. The MCUs support both silicon IGBTs as well as silicon-carbide (SiC) and gallium-nitride (GaN) technologies.
Offering dual 200-kHz control loops, the MCUs also can control six-phase motors. A safe ASIL D software resolver and integrated sine-wave generation plus sigma delta converters eliminate external components. Furthermore, the MCUs support hardware isolation, time-sensitive networking (TSN), and advanced cryptography for next-generation software-defined EVs and zonal vehicle architectures.
Features include:
• Four Arm Cortex-M7 cores at 320 MHz configured as a lockstep pair and two split-lock cores
• Up to 6 MB of flash memory with 800 kB of SRAM
• Two motor-control co-processors
• Safe ASIL D software resolver
• Integrated DSP
• Multichannel analog support
• Six CAN FD interfaces, TSN Ethernet, and programmable I/O
• Hardware security engine (HSE)
• Available in two packages: 176LPQFP-EP and 289MAPBGA
