STMicroelectronics Launch STM32H7P MCUs With AI, DSP Acceleration

GENEVA, Switzerland, Nov 6, 2026 – STMicroelectronics (ST) has introduced the STM32H7P microcontrollers, combining a 520 MHz Arm Cortex-M7 processor with hardware accelerators for digital signal processing (DSP) and edge AI. The devices are designed for digital power systems, motor control, condition monitoring and industrial applications that require real-time processing.
The architecture integrates ST’s Hardware Signal Processor (HSP) and Neural-ART Neural Processing Unit (NPU) alongside the Cortex-M7 core, which delivers a CoreMark score of 2,773.
The HSP accelerates matrix, vector and digital signal processing operations, reducing the workload on the main processor and potentially reducing the need for a external DSP. According to STMicroelectronics, it performs Fast Fourier Transforms (FFTs) up to five times faster than software running on the Cortex-M7.
“The STM32H7P extends the proven STM32H7 series, with two dedicated hardware accelerators alongside a 520MHz Cortex-M7 core that deliver 1.7-times the performance of alternative products on the market. Combining more real-time performance with advanced hardware acceleration for DSP and edge-AI these MCUs let engineers build the next generation of smart, responsive embedded systems across industrial, power electronics, sensing, and intelligent edge applications,” said Laurent Vera, STM32 marketing director, STMicroelectronics. “In addition, richer analog and timer capabilities, and strong cost efficiency are ideal for power electronics applications such as solar, digital power, and motor control.”
AI Acceleration and Real-Time Control
The Neural-ART NPU provides up to 85 giga operations per second (GOPS) for embedded AI workloads.
ST reported the following performance improvements in AI applications:
- Solar inverter safety: Inference ran 40 times faster than software when using ST’s AI Arc Fault Circuit Interrupter (AFCI) model.
- Anomaly detection: The model demonstrated a 20-fold increase in execution speed.
- Battery management: An AI battery-management system (BMS) model ran 15 times faster.
The STM32H7P also features tightly coupled memories (TCM), providing access to instructions and data for control, signal processing and AI inference. The series offers up to 2 MB of flash memory for code and data storage.
For control applications, the microcontrollers incorporate analog-to-digital converters (ADCs), digital-to-analog converters (DACs), comparators and timers inherited from the STM32G5 mixed-signal series. These peripherals support applications involving power electronics, solar energy systems and motor control.
Development Tools and Availability
Developers can use ST Edge AI Suite for machine-learning model development and deployment, along with DSP software resources and the X-CUBE-MCSDK-2 motor-control software tools.
The STM32H7P series will also support the upgraded STM32Cube ecosystem, including the STM32CubeMX2 configurator and HAL2 hardware abstraction layer. The STM32H7P series is currently sampling to original equipment manufacturers (OEMs), with production planned for January 2027.
Designed for industrial environments, the microcontrollers operate at ambient temperatures up to 125°C and are covered by ST’s industrial support program. An exposed-pad low-profile quad flat package (LQFP) option provides additional heat dissipation for high-temperature applications.
The NUCLEO-H7P5II evaluation board and STM32H7P5IDK discovery kit are also scheduled for availability in January 2027.
