Accelerating automotive software design with MCU platform

17 March 2017

NXP Semiconductors launched the S32K1 family combining a breakthrough suite of automotive grade tools and software.

This combination drastically reduces development effort and time to market in a broad range of automotive applications. With 10 of the top 15 global car manufacturers already using S32K in next generation vehicles, this platform sets the future direction of automotive ECU development.

The traditional approach for software development has been to rely on AUTOSAR for automotive- grade drivers, however, not all applications require it. The alternative route is self-development which is labor-intensive, adds qualification requirements and diverts critical resources. As ECU complexity increases, maintaining high-quality software and meeting time-to-market requirements can only be achieved through use of mature, validated sub-system components.

NXP is utilizing its 15+ years of experience in delivering professionally maintained automotive-grade software to minimize development complexity for a broad range of customers regardless of their development approach.

In applications where the use of AUTOSAR is not mandated, NXP is providing an alternative, turn-key option for self-development with a free-of-charge, pre-qualified, automotive-grade software development kit (SDK) that enables rapid prototyping with simple drag and drop functionality. It includes:

MISRA and SPICE Level 3 compliant low-level drivers (LLDs) for all peripherals

Optional application-specific middleware for LIN, NFC and touch sensing
FreeRTOS operating system

Drivers for complementary NXP ICs for faster application bring-up and production readiness e.g. system basis chip (SBC) drivers

Documented source code and out-of-the-box examples eliminating the need for device documentation during application bring-up

The SDK is pre-installed in NXP’s free S32 Design Studio (DS), an Eclipse-based integrated development environment (IDE) supporting multiple compiler and debugger options.

For AUTOSAR applications, NXP standard MCAL and OS support has been expanded with new Complex Device Drivers (CDD) and a new S32K starter kit from ARCCORE significantly lowering cost and complexity barriers to adoption. It is available free of charge for evaluation.

Future-proof hardware
Unlike existing solutions that require multiple MCU platforms to cover a similar range, the initial S32K1 family will span 128KB-2MB of flash memory based on high performance ARM Cortex-M cores. All family members include ISO CAN FD, CSEc hardware security, ASIL-B support and ultra-low-power performance. This scalable approach, combined with a common package strategy and production grade software, maximises reuse allowing customers to react quickly to changing market requirements.
