STM32 High Performance MCUs

Icons on top of a city at night

The STM32 high-performance products and their ecosystem are accelerating innovation for MCU developers. By bringing more performance, more memory and more peripheral resources, ST gives developers more design freedom to take on the challenges of more complex applications.

    The STM32 high-performance MCU platform leverages ST’s nonvolatile memory (NVM) in 90 nm and 40 nm technologies to combine:
  • Best-in-class system performance for code execution, data transfers, and data processing
  • More flexibility: large range of embedded memory densities and advanced peripherals
  • Power efficiency

From entry-level to high-performance microcontrollers, our STM32 high-performance MCU platform includes five compatible product series.

Product types:

STM32H5 series

New STM32H5 microcontrollers are based on Arm® Cortex®-M33 cores and offer the best combination of performance, security, and affordability. They operate at a frequency of up to 250 MHz and feature from 128 Kbytes to 2 MB of flash memory and up to 640 Kbytes of RAM. Beside an exhaustive set of security features, such as crypto graphic accelerators, isolation mechanisms including TrustZone®, STM32H5 additionally provides a certified set of SoC security services maintained by ST over the life of the product.

STM32F4 series

The Arm® Cortex®-M4 based STM32F4 MCU series leverages ST’s NVM technology and ART Accelerator to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 225 DMIPS/608 CoreMark executing from flash memory at up to 180 MHz operating frequency. The STM32F4 series consists of eight compatible product lines of digital signal controllers (DSC), a perfect symbiosis of the real-time control capabilities of an MCU and the signal processing performance of a digital signal processor (DSP).

STM32F2 series

The Arm® Cortex®-M3 based STM32F2 series uses ST’s advanced 90 nm NVM process technology with the innovative adaptive real-time memory accelerator (ART Accelerator) and multilayer bus matrix. This offers an unprecedented trade-off between price and performance. ST’s acceleration technology enables these microcontrollers to achieve up to 150 DMIPS/398 CoreMark at 120 MHz FCPU, which is equivalent to zero wait state execution, while keeping the dynamic current consumption at the outstandingly low level of 175 µA/MHz.

STM32F7 series

Taking advantage of ST’s ART Accelerator as well as an L1 cache, STM32F7 microcontrollers deliver the maximum theoretical performance of the Cortex-M7 core, regardless if code is executed from embedded flash memory or external memory: 1082 CoreMark /462 DMIPS at 216 MHz FCPU.

STM32H7 series

The Arm® Cortex®-M7 based STM32H7 MCU series leverages ST’s (NVM) technology to reach the industry’s highest benchmark scores for Cortex-M-based microcontrollers with up to 1327 DMIPS/ 3224 CoreMark executing from embedded flash memory.

STM32H7RS: a high performance, scalable and secure bootflash MCU

The new STM32H7RS lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7RS is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user flash and 620 KB of flexible SRAM. It is designed for external memory scalability and flexibility accommodating the most demanding application requirements in IoT, medical and industrial settings. 

The STM32H7RS lines cover a general purpose (STM32H7R3/7S3) and graphics line (STM32H7R7/7S7), to address the MPU-like GUI applications. Additionally, the both lines offer advanced security features (including secure boot, secure firmware installation, and hardware encryption/decryption) and target SESIP3 and PSA Certified Level 3 certifications.
