Unlock automotive innovation with Stellar microcontrollers featuring xMemory. Designed for modern vehicles, our advanced memory technology offers unmatched density, reliability, and efficiency. Stellar with xMemory empowers manufacturers to push boundaries in software-defined vehicles and electrification, redefining the driving experience.
Automotive OEMs and Tier 1s often exceed memory budgets by about 30% due to evolving vehicle requirements over the typical two-year development cycle. New use cases like integrating multiple functions, advanced algorithms, AI workloads, and secure over-the-air (OTA) updates (A/B swap) increase memory demands.
Stellar with xMemory addresses these challenges by offering a single automotive-grade device with extensible memory. This efficient and cost-effective solution eliminates the need for multiple devices, reducing development and qualification costs. It allows carmakers to future-proof designs, lower costs, and accelerate time to market with a simpler supply chain.
At the core of Stellar with xMemory is ST's proprietary phase-change memory (PCM) technology. After years of development, ST has delivered the industry's leading embedded non-volatile memory for automotive, featuring the smallest qualified memory bit cell.
Our groundbreaking PCM technology redefines memory density, offering more than twice the memory capacity compared to traditional flash and other emerging embedded NVM technologies.
“With the embedded Phase Change Memory (PCM) technology, Stellar offers a robust and flexible memory concept to create highly performant, adaptable microcontrollers for automotive usage. The technology provides application advantages compared to other memory technologies, such as RRAM and MRAM”.
With increased capacity within the same compact footprint, Stellar with xMemory delivers unmatched performance for your applications, without compromising on space or affordability.
Our Stellar G microcontroller series for gateway and body applications, and Stellar P microcontroller series for motion control, offer unmatched value with more memory, making them the smart, scalable choice for your future-ready automotive projects.
