STM32H7 series of high-performance MCUs with ARM® Cortex®-M7 core

Taking advantage of an L1 cache, STM32H7 devices deliver the maximum theoretical performance of the Cortex-M7 core, regardless if code is executed from embedded Flash or external memory: 2020 CoreMark /856 DMIPS at 400 MHz fCPU

Smart architecture with new generation of peripherals set

The STM32H7 series unleashes the Cortex-M7 core: 

  • AXI and multi-AHB bus matrixes for interconnecting core, peripherals and memories
  • 16 Kbytes +16 Kbytes of I-cache and D-cache
  • Up to 2 Mbytes of embedded dual-bank Flash memory, with ECC and Read-While-Write capability
  • A high-speed master direct memory access (MDMA) controller, two dual-port DMAs with FIFO and request router capabilities for optimal peripheral management, and one additional DMA
  • Chrom-ART acceleration for efficient 2D image copy and double-precision FPU are also part of the acceleration features available in the device
  • Peripheral speed independent from CPU speed (dual-clock support) allowing system clock changes without any impact on peripheral operations
  • Even more peripherals, such as four serial audio interfaces (SAI) with SPDIF output support, three full-duplex I²S interfaces, a SPDIF input interface supporting four inputs, two USB OTG with dedicated power supply and Dual-mode Quad-SPI interface, two FD-CAN controllers, a high-resolution timer, a TFT-LCD controller, a JPEG codec, two SDIO interfaces and many other analog peripherals including three fast 16-bit ADCs, two comparators and two operational amplifiers.
  • 1 Mbyte of SRAM with a scattered architecture:  192 Kbytes of TCM RAM (including 64 Kbytes of ITCM RAM and 128 Kbytes of DTCM RAM for time-critical routines and data), 512 Kbytes, 288 Kbytes and 64 Kbytes of user SRAM, and 4 Kbytes of SRAM in backup domain to keep data in the lowest power modes
