To support the transition toward the software defined vehicle (SDV), ST provides a comprehensive embedded software ecosystem for the Stellar 32 bit automotive MCUs.
This ecosystem is built to handle the complexity of next generation vehicle E/E architectures, combining hardware enforced isolation, deterministic real time control and secure over the air (OTA) software update support.
From advanced integrated development environments and low level driver libraries to production ready AUTOSAR stacks and AI assisted configuration and analysis toolsets, ST provides developers with the essential software building blocks to accelerate automotive innovation. On top of this, we offer end to end AI development support: from data collection and model design, through quantization and seamless integration with AI stacks and libraries, all the way to optimized deployment on ST silicon.
Embedded software solutions for Stellar MCUs
Built for high‑performance integration, Stellar MCUs are supported by an extensive ST software stack for mixed‑criticality automotive applications, from low‑level drivers to complex, safety‑relevant software architectures.
ST’s proprietary MCAL (Microcontroller Abstraction Layer) suite provides production ready, ASIL D–compliant drivers for all key on chip peripherals, ensuring seamless integration with AUTOSAR Basic Software. Fully compatible with AUTOSAR specifications, these drivers are optimized for high performance with minimal memory footprint, helping developers meet tight timing and resource constraints on Stellar MCUs.
Model-based design tools
MathWorksz® develops MATLAB®and Simulink®, leading platforms for data analysis, algorithm development, dynamic system modeling, and embedded code generation. MathWorks products integrate seamlessly with Stellar MCUs, enhancing development workflows through simulation and automatic code generation.
The Model-Based Design Hardware Support Package (HSP) for Stellar MCUs enables the rapid prototyping and debugging of embedded applications within the Simulink graphical environment, including multicore support as well as advanced monitor and tune capabilities during model execution.
Rich ecosystem of third‑party hardware and software tools
Stellar MCUs are supported by a broad ecosystem of third party compilers, debuggers, and programming tools that plug seamlessly into common automotive workflows.
