The STM32H7 microcontrollers from STMicroelectronics are high-performing Arm Cortex-M general-purpose MCUs, combining dual-core punch with power-saving features and enhanced cyber protection.

The devices leverage a 480 MHz version of the Cortex-M7 and add a 240 MHz Cortex-M4 core. With ST’s smart architecture, efficient L1 cache and adaptive real-time ART Accelerator, the MCUs set speed records at 1327 DMIPS and 3224 CoreMark executing from embedded Flash. ST’s Chrom-ART Accelerator delivers an extra boost to graphics performance. To maximise energy efficiency, each core operates in its own power domain and can be turned off individually when not needed.

Developers can easily upgrade existing applications through flexible use of the two cores. They can add a sophisticated user interface to an application such as a motor drive formerly hosted on a single-core Cortex-M4 MCU by migrating legacy code to the STM32H7 Cortex-M4 with the GUI running on the Cortex-M7. The dual-core architecture also helps simplify code development and accelerate time to market in projects where user-interface code may be developed separately from real-time control or communication features.

Compared to Flashless processors, the MCUs deliver high performance with the extra advantage of up to 2 MB Flash and 1 MB SRAM on-chip to handle space constraints and simplify the design of smart objects in industrial, consumer and medical applications with real-time performance or AI-processing requirements. Moreover, the Cortex-M7 level 1 cache and parallel and serial memory interfaces offer unlimited and fast access to external memory.

Additional features include error code correction (ECC) for all Flash and RAM memory to increase safety, multiple 16-bit analog-to-digital converters (ADCs), external ambient-temperature range up to 125°C allowing use in severe environments, an Ethernet controller and multiple FD-CAN controllers giving communication-gateway capabilities, and a high-resolution timer for generating precision waveforms.
