ST Unveils Industrial MCU With AI Accelerator

What happened

STMicroelectronics (ST) unveiled the STM32H7P industrial microcontroller (MCU) on Nov. 10, featuring hardware accelerators for digital signal processing (DSP) and artificial intelligence (AI) workloads. The new MCU combines a 520MHz Arm Cortex-M7 processor with a dedicated hardware signal processor (HSP) and a neural processing unit (NPU), and can be used in industrial equipment for applications including digital power, motor control and condition monitoring. ST said the HSP can reduce processing time by up to 80% compared with conventional CPU-based software processing; the NPU delivers AI computing performance of up to 85 giga operations per second (GOPS); and AI inference for arc fault detection in solar power systems runs 40 times faster than conventional software-based processing. The STM32H7P supports up to 2MB of embedded flash memory, integrates industrial peripherals including analog-to-digital converters (ADCs), digital-to-analog converters (DACs) and timers, and is designed to operate at temperatures of up to 125 degrees Celsius. ST is currently supplying samples to original equipment manufacturers (OEMs), with mass production scheduled to begin in January 2027; pricing for the LQFP100 package with 1MB of flash memory starts at $4.43 per unit for orders of 10,000 units.
