Product details
Overview
STM32H7S7L8H6 from STMicroelectronics is a high-performance Arm® Cortex®-M7 32-bit microcontroller operating at up to 600 MHz, featuring 64 KB flash, 620 KB SRAM (548 KB with ECC), dual FD-CAN interfaces, Ethernet MAC, and hardware-accelerated graphics (NeoChrom GPU2D + Chrom-ART DMA2D). It targets secure, real-time embedded applications requiring deterministic execution, advanced human-machine interface (HMI), and industrial connectivity.
For engineers reviewing the STM32H7S7L8H6 datasheet, STM32H7S7L8H6 pinout, STM32H7S7L8H6 application, or STM32H7S7L8H6 equivalent, key selection considerations include its dual FD-CAN support for automotive diagnostics, PSA Level 2/SESIP Level 3 security certification, 2×12-bit ADCs (5 MSPS), and VFQFPN68 package with 68-pin I/O mapping for space-constrained HMI designs.
Technical Context
The STM32H7S7L8H6 implements a dual-bank Arm Cortex-M7 core with 32+32 KB L1 instruction/data cache, enabling zero-wait-state execution from flash or external memory. Its memory subsystem includes 64 KB user flash, 620 KB SRAM (partitioned into TCM, AXI, and backup RAM), and flexible external memory controllers supporting SDRAM, NOR/NAND, and octo-SPI HyperRAM™ at up to 200 MHz.
Security architecture integrates PSA Level 2 and SESIP Level 3–certified features: secure boot with unique entry point, hardware root of trust (HDP), secure firmware installation (SFI/SFU), two DPA-resistant AES coprocessors, PKA for ECC verification, and on-the-fly encryption of serial/parallel external memories.
