May 12, 2026

Product

H7's main processor is the STMicroelectronics dual-core STM32H747 including an Arm®️ Cortex®️-M7 running at 480 MHz and an Arm®️ Cortex®️-M4 running at 240 MHz. The two cores communicate via a Remote Procedure Call mechanism that allows calling functions on the other processor seamlessly.

Both processors share all the in-chip peripherals and can run:

• Arduino sketches on top of the Arm®️ Mbed™️ OS
• Native Mbed™️ applications
• MicroPython / JavaScript via an interpreter
• TensorFlow™️ Lite

Highlights:

• STM32H747 dual-core processor
• 8 MB SDRAM
• 16 MB NOR Flash
• 10/100 Ethernet Phy
• USB HS
• Secure element
