More on: NXP S32K3 automotive MCU family – Electronics Weekly


Intended for body control, S32K3 family includes single, dual and lockstep M7 core configurations supporting ASIL B/D safety applications, as well as a hardware security engine with the company’s own firmware, and support for firmware over-the-air updates – see the features chart at the bottom of the page.

Applications are foreseen in seats pumps, actuators, access, steering and lighting in fuel and electric vehicles, as well as in electric vehicle battery management.

S32K3–SOFTWARE-STACK 784 The ISO 26262 compliant real-time drivers (both for Autosar and non-autosar) are provided in a package with the hardware. “The inclusion of the production license in the silicon price broadens Autosar access for mass market developers,” according to NXP. The drivers provide “software portability across the entire S32K portfolio from 128kbyte to 8Mbyte and 32pin to 289pin. The use of a common code base and software API helps maximise software reuse across processor platforms”.

It includes:

  • High-level interface for Autosar, low-level interface for non-Autosar
  • ISO 26262 safety compliance up to ASIL D
  • Autosar 4.4 including multi-core and security support
  • IP coverage via Autosar standard and complex device drivers
  • Configurable using NXP’s S32 configuration tool or Autosar partner toolchains

The firmware for the hardware security engine mentioned above is also complimentary, as is an ‘inter-platform communication framework’ – middleware for managing communication and resources in multi-core systems.

A ‘safety software framework’ with safety libraries for fault detection and reaction mechanisms is available under license, providing a foundation for ISO 26262 compliance.

S32K3 samples, evaluation boards and developer resources are scheduled to be available from early November :

S32K3 family feature planning

The S32K3 product page is here. The data sheets need at least a sign-in, but worthwhile information can be gleaned from the freely-available S32K1 to S32K3 and Real Time Drivers migration guides, and an application note on the S32K3 memories.
