Future-proof your designs, accelerate development, and simplify logistics
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.
Why is Stellar with xMemory
the ideal MCU for SDV?
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.
