STMicroelectronics STM32H750XBH6

Overview

STM32H750XBH6 from STMicroelectronics is a 32-bit Arm® Cortex®-M7 microcontroller operating at up to 480 MHz, featuring 128 Kbytes of flash, 1 Mbyte of RAM (including 192 Kbytes TCM), and integrated cryptographic acceleration (AES-256, SHA-2, RNG). It supports dual-domain power management (D1/D2/D3), 3× PLLs with fractional mode, and 46 communication/analog peripherals - deployed in industrial HMI, motor control gateways, and secure edge nodes requiring deterministic real-time response.

For engineers reviewing the STM32H750XBH6 datasheet, STM32H750XBH6 pinout, STM32H750XBH6 application, or STM32H750XBH6 equivalent, key selection criteria include its 480 MHz Cortex-M7 core with L1 cache, 1 Mbyte RAM partitioning (ITCM/DTCM/backup SRAM), dual CAN FD + Ethernet MAC support, hardware JPEG codec, and voltage scaling across six Run/Stop modes.

Technical Context

The STM32H750XBH6 implements a triple-domain power architecture (D1 high-performance, D2 comms/timers, D3 reset/clock/PM) with independent clock gating and voltage scaling. Its interconnect uses one AXI and two AHB bus matrices, bridged via five AHB2-APB and two AXI2-AHB bridges to enable concurrent high-bandwidth peripheral access.

It integrates four DMA controllers: one high-speed MDMA with linked-list support, two dual-port DMAs with FIFO, and one basic DMA with request routing - offloading CPU for sensor fusion, audio streaming, and real-time control loops without latency penalty.

FAQ

What is the maximum operating frequency and how is it achieved?

The STM32H750XBH6 achieves 480 MHz via its main PLL configured with fractional-N synthesis, fed by the 4–48 MHz HSE or 64 MHz HSI. The core's L1 instruction and data caches (16 KB each) and tightly coupled memories (ITCM/DTCM) eliminate wait states, sustaining 1027 DMIPS at full speed without pipeline stalls.

Does this MCU support external SDRAM, and what interface is used?

Yes - the Flexible Memory Controller (FMC) supports SDRAM and LPDDR SDRAM with up to 32-bit data bus width and synchronous clocking up to 133 MHz. It implements standard SDRAM command sequences (ACTIVATE, READ, WRITE, PRECHARGE) and auto-refresh, enabling direct connection to 64 MB IS42S16400J-6BL or compatible devices.

How does the dual-domain power architecture improve system-level energy efficiency?

The D1/D2/D3 domain separation allows independent clock gating and voltage scaling: D1 (core/peripherals) can run at full 1.2 V while D2 (comms) operates at 1.0 V and D3 (reset/RTC) remains at 0.9 V. This reduces dynamic power by >40% in partial-active modes versus monolithic voltage domains.

Can the hardware JPEG codec process YUV422 video streams in real time?

No - the JPEG codec handles still-image compression/decompression only (baseline JPEG). It supports YUV422 input but requires external preprocessing for video; frame-rate throughput is limited to ~15 fps at QVGA resolution due to internal 32-bit AXI bandwidth constraints.
