STMicroelectronics STM32H753AII6

Overview

STM32H753AII6 from STMicroelectronics is a 32-bit Arm® Cortex®-M7 microcontroller operating at up to 480 MHz, featuring 2 MB flash, 1 MB RAM (including 192 KB TCM), dual-domain power management, and integrated cryptographic acceleration (AES-256, HASH, RNG). It supports CAN FD, Ethernet MAC, LCD-TFT controller, and JPEG codec - deployed in industrial HMI, motor control gateways, and secure edge nodes.

For engineers reviewing the STM32H753AII6 datasheet, STM32H753AII6 pinout, STM32H753AII6 application, or STM32H753AII6 equivalent, key selection criteria include dual-bank flash with read-while-write, voltage-scaling across six ranges, 168 GPIOs with interrupt capability, and hardware-accelerated crypto for firmware integrity verification.

Technical Context

The device implements a three-domain power architecture (D1/D2/D3) enabling independent clock gating and domain shutdown - critical for real-time task isolation and low-power operation. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB bridges, supporting concurrent high-bandwidth peripheral access without CPU contention.

It integrates four DMA controllers including a high-speed MDMA with linked-list support, two dual-port DMAs with FIFO, and a basic DMA with request routing - enabling zero-CPU-overhead data movement between peripherals, memory, and external interfaces like FMC, QUADSPI, and SDMMC.

FAQ

What is the maximum operating frequency and core configuration of the STM32H753AII6?

The STM32H753AII6 features an Arm Cortex-M7 core running at up to 480 MHz with double-precision floating-point unit, 16 KB instruction cache, and 16 KB data cache. It delivers 1027 DMIPS at 480 MHz (2.14 DMIPS/MHz) and includes a memory protection unit (MPU) for secure task isolation.

Does the STM32H753AII6 support hardware-accelerated cryptography?

Yes - it integrates dedicated cryptographic accelerators for AES-128/192/256, TDES, SHA-1/SHA-2, HMAC, and a true random number generator (TRNG). These blocks operate independently of the CPU and support secure boot, encrypted firmware updates, and TLS offload in edge-node applications.

What package type and pin count does the STM32H753AII6 use?

The STM32H753AII6 uses a 100-pin LQFP package (14 × 14 mm, 0.5 mm pitch), designated as LQFP100 in ST's documentation. This variant provides 168 GPIOs (including multiplexed functions), with pin assignments validated per ST's DS12117 Rev 10 datasheet section 5.

How does the power architecture support low-power operation?

The device implements three independent power domains (D1/D2/D3) with configurable voltage scaling across six ranges. In Standby mode with RTC and LSE active but backup SRAM disabled, it draws only 2.95 µA - enabled by dedicated low-power regulators, automatic domain gating, and retention-capable SRAM partitions.
