STM32 High Performance MCUs

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.

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).

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 F_CPU, which is equivalent to zero wait state execution, while keeping the dynamic current consumption at the outstandingly low level of 175 µA/MHz.

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 F_CPU.

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.

The STM32N6 is based on the Arm Cortex-M55 running at 800 MHz. The STM32N6 series includes a lineup of devices that embed the ST Neural-ART accelerator, an in-house developed neural processing unit (NPU). The ST Neural-ART on the STM32N6 targets low power, high performance, and cost-effective edge AI applications. STM32N6 MCUs also incorporate an image signal processor (ISP) and several multimedia accelerators, opening the door to advanced computer vision applications.
