STMicroelectronics introduces Stellar with xMemory for automotive microcontrollers in software-defined vehicles and electrification

Stellar with xMemory addresses the complexities of managing multiple devices with varying memory options, offering a single, innovative device with extensible memory. This approach simplifies the development process, reduces costs, and accelerates time to market. By integrating extensible memory, carmakers can future-proof their designs, allowing for additional innovation throughout the vehicle's lifecycle

 

Key Benefits and Features

    Cost-Effective Development: Stellar with xMemory reduces development and qualification costs by eliminating the need for multiple devices with different memory configurations.

 

    Future-Proof Designs: The extensible memory allows for seamless upgrades and innovations, ensuring that carmakers can continuously enhance their products.
    Simplified Supply Chain: A single device with extensible memory streamlines logistics and reduces the complexity of the supply chain.

 

    Enhanced Performance: Embedded Phase Change Memory (PCM) technology provides robust and flexible memory solutions, outperforming other memory technologies such as RRAM and MRAM.

“ST has developed the ultimate memory technology for the automobile market with the smallest bit cell to meet the endless need for more memory. Stellar with xMemory will streamline the car architectures of tomorrow, making them more cost-effective and significantly reduce development time for carmakers,” said Luca Rodeschini, Group Vice President and General Purpose and Automotive Microcontrollers Division General Manager, STMicroelectronics.

Axel Aue, Vice President at Bosch, added, “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.”

STMicroelectronics has been at the forefront of transitioning from Flash to eNVM technology in automotive MCUs. The embedded Phase-Change Memory used in Stellar with xMemory offers the best power, performance, and area (PPA) index among NVM technologies. With the industry's smallest eNVM cell size, PCM fabricated at 18nm and 28nm nodes provides twice the memory density of other technologies.
