STMicroelectronics STM32H753XIH6

Overview

STM32H753XIH6 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 CAN FD interfaces, hardware JPEG codec, and cryptographic acceleration (AES-256, SHA-2, RNG). It serves as a high-performance application processor in industrial HMI, motor control gateways, and secure edge nodes requiring real-time determinism and rich peripheral integration.

For engineers reviewing the STM32H753XIH6 datasheet, STM32H753XIH6 pinout, STM32H753XIH6 application, or STM32H753XIH6 equivalent, key selection criteria include its triple-domain power architecture (D1/D2/D3), 16-bit ADCs with 3.6 MSPS, HDMI-CEC and SPDIFRX support, and UFBGA169 package compatibility with high-density PCB layouts.

Technical Context

The STM32H753XIH6 implements a split-power-domain architecture with independent D1 (Cortex-M7 core + AXI bus), D2 (peripherals + AHB), and D3 (reset/clock/PMU) domains, enabling granular clock gating and voltage scaling across six configurable ranges. Its interconnect matrix comprises one AXI and two AHB bus matrices with five AHB2-APB and two AXI2-AHB bridges for deterministic low-latency peripheral access.

It integrates three PLLs - one system PLL with fractional-N capability for precise clock synthesis, plus two kernel PLLs supporting independent clock trees for USB/Ethernet, audio, and ADC subsystems - enabling simultaneous high-speed operation of multiple timing-critical peripherals without jitter coupling.

FAQ

What is the maximum operating frequency of the STM32H753XIH6's Cortex-M7 core?

The STM32H753XIH6 operates its Arm Cortex-M7 core at up to 480 MHz, achieving 1027 DMIPS and 2.14 DMIPS/MHz (Dhrystone 2.1). This frequency is sustained under full voltage scaling range 0 (VOS0) with proper thermal management and stable 1.2 V core supply derived from the internal LDO regulated by VCAP capacitors.

Does the STM32H753XIH6 support external SDRAM, and what interface is used?

Yes, the STM32H753XIH6 supports external SDRAM up to 256 MB via its Flexible Memory Controller (FMC), which provides a 32-bit data bus and programmable timing registers. It also supports LPDDR/DDR SDRAM in synchronous mode up to 100 MHz, with dedicated control signals including RAS/CAS, bank address, and row/column address multiplexing.

How many independent power domains does the STM32H753XIH6 feature, and what do they control?

The STM32H753XIH6 features three independent power domains: D1 manages the Cortex-M7 core, AXI bus, and high-performance peripherals; D2 controls communication interfaces (USB, Ethernet, CAN), timers, and DMA controllers; D3 handles reset, clock control, and power management logic - each domain supports independent clock gating and voltage scaling.

Can the STM32H753XIH6 execute cryptographic operations without CPU intervention?

Yes, the STM32H753XIH6 includes dedicated hardware accelerators for AES-128/192/256, TDES, HASH (MD5/SHA-1/SHA-2), HMAC, and true random number generation. These operate independently via DMA-triggered engines, allowing background encryption of large data blocks while the CPU executes application code or enters low-power modes.
