Product details
Overview
STM32H7R3Z8T6 from STMicroelectronics is an 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, Ethernet MAC, and NeoChrom GPU2D for advanced graphics acceleration. It targets high-performance industrial HMI, real-time motor control, and connected edge devices requiring deterministic execution and secure firmware updates.
For engineers reviewing the STM32H7R3Z8T6 datasheet, STM32H7R3Z8T6 pinout, STM32H7R3Z8T6 application, or STM32H7R3Z8T6 equivalent, key selection criteria include its 600 MHz M7 core with L1 cache, dual FD-CAN support, integrated SMPS regulator, hardware JPEG codec, and TFBGA100 (A08Q) package with 100 I/Os - all critical for space-constrained, power-aware embedded designs.
Technical Context
The device implements a dual-bank Arm Cortex-M7 core with MPU, DP-FPU, and 32+32 KB L1 instruction/data cache enabling zero-wait-state execution from flash or external memory. Its memory architecture includes 64 KB user flash, 620 KB SRAM (split into TCM, AXI, and backup sections), and flexible external interfaces including FMC, octo-SPI, and SDIO.
Security is enforced via root-of-trust boot, secure hide protection area (HDP), embedded RSS for secure firmware installation (SFI/SFU), and hardware accelerators for PKA (ECC verification only), HASH, and NIST SP800-90B-compliant RNG. Graphics subsystem integrates NeoChrom GPU2D, Chrom-ART DMA2D, and Chrom-GRC (GFXMMU) for optimized 2D rendering and memory bandwidth reduction.
