STMicroelectronics' Latest STM32H7 Part, the STM32H7P, Packs Edge Compute and DSP Acceleration

STMicroelectronics has announced another new entry for its unified STM32 ecosystem, the STM32H7P — designed with improved machine learning performance and a dedicated digital signal processor (DSP) and built with industrial automation systems firmly in mind.

"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," claims STMicro's Laurent Vera of the new part. "Combining more real-time performance with advanced hardware acceleration for DSP and edge-AI [Artificial Intelligence, formerly known as tinyML] these MCUs [Microcontroller Units] let engineers build the next generation of smart, responsive embedded systems across industrial, power electronics, sensing, and intelligent edge applications. 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."

The performance-focused parts, which are the latest in STMicro's efforts to expand the STM32 ecosystem into a one-stop shop for everything from energy-efficient embedded devices to high-performance robotics and safety-critical systems, are built around a single Arm Cortex-A7 core running at up to 520MHz. To this, the company has added a Neural-ART coprocessor offering up to 85 giga-operations per second (GOPS) of minimum-precision compute for on-device machine-learning applications, plus a dedicated digital signal processor (DSP) that it claims delivers an almost fivefold performance gain for Fast Fourier Transform (FFT) operations over running on the CPU in software.

Other features include the use of a Tightly-Coupled Memory (TCM) architecture, analog peripherals including analog to digital and digital to analog converters (ADCs and DACs) plus comparators, timers borrowed from the STM32G5 mixed-signal chips, and an industrial rating that promises reliable operation in ambient temperatures up to 125°C (257°F). Interestingly, STMicro is also positioning it as an affordable alternative to earlier STM32H7-series models — promising 2MB of flash storage at "a price point similar" to its 1MB predecessors.

The STM32H7P is sampling now, the company has confirmed, with production scheduled for January 2027 at pricing of $4.43 per unit for a 1MB LQFP100-package variant in 10,000-unit quantities; additional information is available on the official product page, while a Discovery Kit development board featuring the part will launch in January.
