STMicroelectronics’ STM32H7P MCUs embed digital signal processing, edge-AI, and real-time control for demanding industrial applications

What happened

STMicroelectronics introduced the STM32H7P microcontrollers, adding two dedicated hardware accelerators alongside the Arm Cortex-M7 core (520MHz, 2773 CoreMark): a Hardware Signal Processor (HSP) for matrix, vector, and digital signal processing, and a Neural-ART Neural Processing Unit (NPU) bringing up to 85 GOPS. The HSP cuts FFT processing time by up to 5 times compared to software implementation on the Cortex-M7; the NPU has already demonstrated 40-times faster inference than software running ST's AI Arc Fault Circuit Interrupter (AFCI) model, with the anomaly detection model shown to run 20 times faster and the AI battery-management system (BMS) model 15 times faster. The new series offers up to 2MB of Flash at a price point similar to the previous 1MB STM32H7 series, and its analog peripherals and timers are inherited from the newly introduced STM32G5 mixed-signal series. The MCUs operate up to 125°C ambient temperature and are included in ST's industrial longevity support program.
