STMicroelectronics future-proofs the development of next-gen carswith innovative memory solution for automotive microcontrollers New Stellar microcontrollers with xMemory enable simpler, more scalable computing platform for developing software-defined vehicles and evolving electric vehicle architectures Extensible capability equips carmakers for continuous innovation, including more memory-hungry AI applications xMemory, based on ST proprietary phase-change memory (PCM) technology, will start production later in 2025 Geneva, Switzerland, April 16, 2025 -- STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has announced Stellar with xMemory, a new generation of extensible memory embedded into its Stellar series of automotive microcontrollers, that transforms the challenging process of developing software-defined vehicles (SDV) and evolving platforms for electrification. Instead of managing multiple devices with varying memory options and the associated development and qualification costs, Stellar with xMemory introduces a single, innovative device with extensible memory, providing customers with an efficient and cost-effective solution.
Stellar MCUs with xMemory are competitively priced to bring additional savings, simplify the OEM supply chain, and accelerate time to market by lengthening the product lifetime and maximizing reuse across projects to reduce time for qualification. Technical notes for editors on PCM and Stellar: ST has been at the forefront of the transition from Flash to eNVM technology in automotive MCUs, introducing the first 28nm eNVM qualified for automotive applications, which is at the core of the xMemory.
Stellar with xMemory will be first available on the Stellar P6 MCUs, which target the new drivetrain trends and architectures for electric vehicles (EVs), with production to start later in 2025. "ST has developed the ultimate memory technology for the automobile market with the smallest bit cell to meet the endless need for more memory.
