The STM32H7 (Cortex-M7) is STMicroelectronics’s 32-bit ARM Cortex-M7 (M4 co-proc). STM32H7 is ST’s highest-performance Cortex-M family, running a 400-480 MHz dual-core (M7 + M4) pipeline with up to 2 MB of Flash and over 1 MB of SRAM for graphics, AI and real-time control.

Readout Protection on STM32H7 (Cortex-M7)
STM32H7 extends RDP Level 0/1/2 with WRP, PCROP, secure user memory, and on some parts a hardware secure boot and trust-zone style isolation, making unprotected extraction a real engineering task. For any locked STM32H7 (Cortex-M7) we start from the silicon, not the programming header, because the protection is designed to refuse a clean external read.
Flash Extraction & Clone Workflow
When a customer ships us a protected STM32H7 (Cortex-M7), the work usually follows the same path: identify the exact package and die, then carry out RDP Level-2 containment and external-memory-interface (FMC/quad-SPI) dump on the 743/745 die. We read the internal memory non-destructively where the protection allows, reconstruct the binary or hex image, verify it against a known-good checksum, and finally program a blank device or deliver the recovered firmware. Every step is documented so the result can be reproduced or re-used for production cloning.
