STMicroelectronics raises the performance bar for embedded edge AI and industrial applications with the new STM32V8 high-performance microcontrollers (MCUs) for demanding industrial applications such as factory automation, motor control, and robotics. It is the first MCU built on ST’s 18-nm silicon-on-insulator (FD-SOI) process technology with embedded phase-change memory (PCM).
The STM32V8’s phase-change non-volatile memory (PCM) claims the smallest cell size on the market, enabling 4 MB of embedded non-volatile memory (NVM).
In addition, the STM32V8 is ST’s fastest STM32 MCU to date, designed for high reliability and harsh environments in embedded and edge AI applications, and can handle complex applications and maintain high energy efficiency. The STM32V8 achieves clock speeds of up to 800 MHz, thanks to the Arm Cortex-M85 core and the 18-nm FD-SOI process with embedded PCM. The FD-SOI technology delivers high energy efficiency and supports a maximum junction temperature of up to 140°C.
The MCU integrates special accelerators, including graphic, crypto/hash, and comes with a large selection of IP, including 1-Gb Ethernet, digital interfaces (FD-CAN, octo/hexa xSPI, I2C, UART/USART, and USB), analog peripherals, and timers. It also features state-of-the-art security with the STM32 Trust framework and the latest cryptographic algorithms and lifecycle management standards. It targets PSA Certified Level 3 and SESIP certification to meet compliance with the upcoming Cyber-Resilience Act (CRA).
The STM32V8 has been selected for the SpaceX Starlink constellation, using it in a mini laser system that connects the satellites traveling at extremely high speeds in low Earth orbit (LEO), ST said. This is thanks in part to the 18-nm FD-SOI technology that provides a higher level of reliability and robustness.
The STM32V8 supports bare-metal or RTOS-based development. It is supported by ST’s development resources, including STM32Cube software development and turnkey hardware including Discovery kits and Nucleo evaluation boards.
The STM32V8 is in early-stage access for selected customers. Key OEM availability will start in the first quarter of 2026, followed by broader availability.
